Such connections shall be made with approved check valves positioned with direction of flow from low to high pressure, and a fire hydrant shall be installed on the high- pressure side of the check valve. The check valve shall be installed in a standard manhole. A four foot manhole shall be used for six and eight-inch valves and a five foot manhole for twelve-inch valves. Larger size check valves shall be housed in a vault, and the size of the vault shall be approved by the Public Works Director. 5) Mains twelve inches and larger in diameter which have a change in elevation of ten-feet or greater shall have an air release valve installed at the highest elevation of such change. Additional air release valves may be required by the Public Works Director on mains less than 12-inches based on elevation changes of fifteen-feet or greater. Town of Lillington Detailed Water Specifications Page 7 Town of Lillington Detailed Water Specifications Page 7 6) Any water service customer which has a water static pressure greater than eighty (80) psi is required by North Carolina State Building Code to install and maintain a pressure reducing valve. The pressure reducing valve will be installed on the building service line after the meter. Such a device must be installed before the Town of Lillington will allow the actual water connection. This installation is covered by the Plumbing Code and is not maintained by the Public Works Department. 7) Pressure reducing and/or sustaining stations shall be installed when directed by the Public Works Director to connect high and low pressure systems. The pressure reducing valve shall allow enough flow from the high side to maintain a specified pressure on the low side and will not reduce the high side below a certain amount. This type valve will be a pressure sustaining/ pressure reducing valve. 8) Valves over 4-feet in depth must have a valve stem extension to bring operating nut to a depth of no more than 4-feet. When valve extension kits are used, they shall be manufactured by the same company which manufactured the valve. 9) Insert valves are only to be installed on a case-by-case basis as approved by the Public Works Director. e. Meters All water services will be metered, and the meter will be located in the rights-of– way or in a 2 foot easement adjacent to the rights-of–way. Meters sizes shall be 5/8” x 3/4”, 1”, 1 ½”, 2”, 3, 4”, 6”, 8”, or 10” with no exceptions. Any single water service that is to be used for fire service will have a minimum pipe size of 6-inch in diameter, pressure class 350 ductile iron pipe. All single water services that are used for fire service will be required to have a Fire Service Meter with a by-pass meter. Meters will be the same size in diameter as the service. The only exceptions are a 10- inch Fire Service Meter with a by-pass on a 12-inch water service line and a 5/8” residential meter on a 3/4” water service line. 1) If one common meter is used, it should be located in the right-of-way. However, when a sidewalk is exists, the meter may be located in a 2-foot easement adjacent to the right-of-way. In no case shall meters be located inside of buildings. 2) The Town City will maintain all water connections within the street right-of-way at no charge to the property owner. Repairs on private property shall be the responsibility of the property owner or customer. Town of Lillington Detailed Water Specifications Page 8 Town of Lillington Detailed Water Specifications Page 8 3) The Town’s responsibility will end at the customers side of the meter. Any and all repairs beyond that point will be the responsibility of the contractor or home owner. 4) All home owners within the Town’s corporate limits and attached to the Town’s water system will be required to have cutoff (either gate valve or butterfly valve) installed within a cast iron or composite meter box for the water service on their side of the meter. Service lines outside of the Town’s meter box and will be maintained by the home owner. Meter or valve boxes subject to vehicular traffic shall be H-20 traffic rated. f. Water Backflow/Cross Connection 1) All existing and proposed water services, dedicated fire and irrigation lines and private distribution systems must be provided with an approved backflow prevention assembly based on a "schedule of compliance" as determined by the Public Works Director. For projects having any combination of these lines, suitable approved assemblies must be provided for containment of each level. Questions concerning the Town of Lillington Backflow/Cross-Connection Prevention Program should be directed to the Public Works Cross Connection Coordinator. 2) On service lines serving a facility that is in operation continuously, the lines must have parallel backflow prevention assemblies on a single service line or adequate protection on each supply line to that facility. On parallel installations each assembly must be the same type (two double check valve assemblies, two double detector check valve assemblies, two reduced pressure zone device assemblies, or two reduced pressure zone detector check assemblies). In some cases, these assemblies must be the same size as the service line. The rule to normally use in this situation is that the assembly must have the square of the diameters equal to the square of the supply service "tap". For example, an 8-inch service line would need at a minimum two 6-inch devices in parallel. 3) The Public Works Department approved backflow prevention assemblies shall be installed above ground. Assemblies may be installed inside of buildings as long as there are no unprotected taps between the meter and the building. The minimum drain size in an above ground vault for double check assemblies and double detector check valves is 4 inches. An approved dual check valve must be installed at the meter service on single family residential service lines. OS&Y shut-off valves shall be used on all fire line backflow prevention assemblies (2 ½" or larger). All testable backflow prevention assemblies shall have approved test cock. 4) If the fire lines, private distribution systems or domestic service lines are connected to any "processed water" sources, or booster pump system, backflow protection shall be provided by using the USC approved Reduced Pressure zone assembly (RPZ) type assembly (fire lines require a reduced Town of Lillington Detailed Water Specifications Page 9 Town of Lillington Detailed Water Specifications Page 9 pressure detector assembly). "Processed water" is water where extra chemicals are added by the user on site to reduce freezing, pipe corrosion, etc. This RPZ assembly shall include the resilient wedge valves and test cocks, and the RPZ unit shall meet the requirements of AWWA standard C- 511. If the RPZ assembly is 2½" or larger, then it must be supplied with OS&Y shut-off valves. The unit shall be housed in an above ground vault, insulated above ground enclosure, or inside of a building. RPZ’s are required on all mall service connections due to change of use. No RPZ’s may be installed below ground. 5) If the backflow preventer is located on site for fire lines, then it shall be located outside the structure, which it is serving unless otherwise approved by the Public Works Department. If there are no unprotected taps between the street and building it can be located in the building. All internal or confinement assemblies (isolation assemblies) will have strainers upstream of the device with the exception of devices on fire lines. 6) No person shall fill special use tanks or tankers containing pesticides, fertilizers, or other toxic chemicals or their residues from a public water system except at a location equipped with an approved air gap (2 X diameter of supply pipe with a minimum gap of 1”) or an approved reduced pressure backflow preventer properly installed on the public water supply. No supplier of water shall permit the filling of such special use containers except at locations so equipped. 7) Backflow prevention assemblies shall be installed at a minimum height of 12 inches and a maximum height of 60 inches above the floor or ground. Assemblies shall also have a clear horizontal distance of 18 inches around the entire diameter of the device. 8) The backflow prevention assembly(s) must be readily accessible at all times. Readily accessible means that only a one-piece cover must be removed for an outside installation to test or perform maintenance on the assembly. 9) Defacing a backflow prevention assembly will not be allowed. Defacing would include anything that might obscure pertinent information on that assembly (i.e.) nameplate, serial number, etc. Any assembly that is missing a nametag or information stamped in the body will not be considered to be an acceptable assembly installation and must be replaced upon notification by the Town of Lillington (This applies to new assemblies only). 10) Backflow prevention assemblies must be installed, tested and maintained by persons that have completed the Cross Connection School. It is also required that all assemblies be tested* at the time of installation and annually thereafter. All assemblies must also have the rubber parts changed every five years. Town of Lillington Detailed Water Specifications Page 10 Town of Lillington Detailed Water Specifications Page 10 The list of approved test equipment follows: Mid-West Model 830, 844, & 845 Watts TK-DP, All assemblies Watts TK-99D Pro-Master RP Test kit * Test equipment shall be calibrated yearly. All assemblies ¾-inch – 2-inch must have a ball valve that is full port, have a blow-out proof stem, have resilient seats and a 400 psi WOG rating (water, oil or gas). All assemblies 2 ½-inch–10-inch must have fusion bonded, epoxy coated resilient wedge valve. All test cocks must be approved ball valves of the appropriate size. 11) All backflow prevention assemblies installed outside of buildings must be installed in an approved enclosure with the exception of residential lawn irrigation backflow prevention assemblies. All enclosures shall be insulated and shall meet the requirements of American Society of Sanitary Engineering (ASSE) Standard 1060. 12) Double check valves and double detector check valves may be installed horizontally or vertically (see approved list). Reduced pressure backflow prevention assemblies shall be installed only horizontally. 13) All fire sprinkler system backflow prevention assembly enclosures shall be equipped with a heater that is recommended by the enclosure manufacturer. 14) The Owner/Customer shall be responsible to provide adequate power for the operation of the aforementioned heater. g. Installation Restrictions for Design 1) All water mains, of proper size as determined by the Public Works Department, shall be installed complete, along all boundaries abutting existing public roadways, from property line to property line regardless of the land use, proposed lot arrangement of the subdivided property or the availability of connection to a main in service. Within all dead-end streets that may be extended, the water main must extend to the property line of the subdivision. 2) All water mains shall be installed with a minimum cover of 3-feet from the top of finished ground to pipe crown and shall be in accordance with all applicable NCDEQ Public Water Supply and Town of Lillington Standards. 3) When mains are to be installed to a dead end or mains are stubbed for future extension, the main shall end with at least one full 18-foot joint of pipe, or more when required.

When two mains exist within the street right-of-way, the main which provides the best flow and pressure for that parcel shall be tapped. This determination shall be made by the Public Works Department. No service connections are to be made off of fire hydrant branches. 5) Two (2) 45o bends shall be utilized for 90o turns of the water mains or branches. 90o bends are not allowed in the water distribution system without prior approval from the Town of Lillington Public Works Director. 6) All meters must be installed one (1) foot inside of the right-of-way or in approved easements. Meters must be installed adjoining the property they are serving and located on the same street as property address. 7) In non-residential water distribution systems, water meters may be located in the rear of the building with prior approval by the Public Works Department. The meters will be installed such that the meter locations conform to the units in the building as viewed from the rear of the building. The meters must be installed in an elevated area behind permanent curb and gutter or protected by bollards so that vehicles cannot be located over the meters. Each individual meter must be labeled on the exterior with the address on a painted sign or painted on the pavement at the meter. Each meter setter must also have a permanent weatherproof tag wired on the angle valve by the plumber. The following is a chart with the recommended residential water service sizes: Full # Static water pressure Recommended Bathrooms service sizes 1 any ¾” 2-3 > 60 p.s.i. ¾” 2-3 < 60 p.s.i. 1” > 4 any 1” 8) When multi-family developments and non-residential land uses are using multiple adjacent meter installation, then the construction plans shall show the unit and meter numbering sequence for each building.

PIPE INSTALLATION a. All water pipe and appurtenances shall be installed in accordance with the requirements of AWWA C-600 for ductile iron pipes and AWWA C-605 for PVC pipe. b. Water pipe shall be laid to the line and grade shown on the plans with all valves and hydrants located as shown on the plans. c. Protection shall be afforded to all underground and surface structures using methods acceptable to the Public Works Director or Town’s Engineer. This protection shall be furnished by the contractor at the contractors' own expense. d. Deviation from line and grade may be made only on revised plans upon approval by Public Works Department and identified on “as-builts” when such deviations arise from grade or line conflicts with existing utilities, structures or other sources of conflict. e. Subsurface explorations shall be made by the contractor at the direction of the Public Works Director or Engineer where it is necessary to determine the location of existing pipes, valves or other underground structures. f. Depth of pipe cover, unless shown otherwise on the plans shall be three feet above top of pipe. Depth of cover shall be measured from the established street grade or the surface of the permanent improvement to the top of the barrel of the pipe. When water lines are installed along a roadway that could be widened in the future, they shall be installed at sufficient depth to maintain four feet of cover from crown of pipe to the subgrade of any future road improvements including potential vertical alignment changes. Additional depth may be required in areas where future road Town of Lillington Detailed Water Specifications Page 38 Town of Lillington Detailed Water Specifications Page 38 widenings may conflict with buried pipe. The water main shall be located horizontally so as not to conflict with future storm drainage systems. g. After the foundation has been properly graded, bedded when applicable, and the bell holes dug, the pipe and accessories shall be carefully lowered into the trench by approved methods. Under no circumstances shall the pipe or accessories be dropped or dumped into the trench. All damaged pipe and accessories shall be removed from the job. h. After each pipe has been brought to grade, aligned, and placed in final position, deposit and densify sufficient bedding material under the pipe haunches and on each side of the pipe to hold the pipe in proper position during subsequent pipe jointing, bedding, and backfilling operations. Bedding material shall be uniformly and simultaneously deposited on each side of the pipe to prevent lateral displacement. i. Any pipe showing evidence of oil, tar or grease shall be permanently marked and removed from the job. j. Laying of pipe and jointing of pipe shall be done according to manufacturer's recommendation with care being taken to provide uniform bearing for the pipe. Bell and spigot of pipe shall be cleaned and properly lubricated where a mechanical joint of a "push on" type joint is employed. No chlorine powder or tablets shall be put in the lines during installation. k. Open ends of pipe shall be plugged with a standard plug or cap at all times when pipe laying is not in progress. Trench water shall not be permitted to enter pipe. l. Pipe cutting for inserting valves, fittings or closure pieces shall be done in a neat and workmanlike manner in accordance with the manufacturer's recommendations and without damage to the pipe. m. Bell ends will face the direction of laying unless otherwise directed by the Public Works Director or Engineer. For lines on an appreciable slope, the Public Works Director or Engineer may also require that bell ends face upgrade. n. Maximum horizontal deflections for ductile iron pipe shall not exceed the manufactures recommended maximum deflection for an eighteen foot joint of pipe. o. Separation Distances 1) All pipeline systems shall meet either the separation distances provided below, or the minimum separation distances as required by NCDEQ (15A NCAC 18C.906, 15A NCAC 02T.305 and Recommended Standards for Water Works – Ten State Standards) or any other County, State, or Federal agency, whichever is greater. Town of Lillington Detailed Water Specifications Page 39 Town of Lillington Detailed Water Specifications Page 39 2) All distances are measured from outside diameter to outside diameter. 3) If an engineer demonstrates it is impracticable to maintain the separation distances required by this Rule, taking into consideration feasibility, cost, and the factors set forth in this Paragraph, the deviation may be approved on a case-by-case basis, if supported by data and alternative construction criteria provided by the design engineer in accordance with 15A NCAC 18C .0906 (f) 4) When installing a water main, the horizontal separation between water and sewer shall be ten-feet. If this separation cannot be maintained due to existing conditions, the only variation allowed is the water main in a separate trench with three feet of separation, and the elevation of the water main at least 18- inches above the top of the sewer and both water and sewer must be Ductile Iron pipe for 10-feet in either direction on both pipes. 5) To allow for construction and repair, a minimum distance of 24-inches shall be maintained between the outside of the water main and the outside of other utilities if the difference in pipeline elevation is no greater than 24 inches. If the vertical difference between the parallel pipelines exceeds 24 inches, the horizontal separation distance shall be determined on a case-by-case basis by the Public Works Director. The critical factor is being able to excavate the deeper pipeline for repairs and not disturbing the shallower pipeline. 6) A water main that crosses a sewer shall be laid a minimum vertical distance of 18 inches from the outside of the water main and the outside of the sewer, either above or below the sewer, with preference to the water main located above the sewer. One full length of water pipe shall be located so that both joints will be as far from the sewer as possible.. The crossing of other underground pipe requires a minimum of twenty-four inches of vertical separation. Any changes in these clearances must be approved by the Public Works Director. All crossings within these vertical clearances shall be filled with #67 stone. All distances are measured from outside diameter to outside diameter. 7) Water system piping and stormwater system piping shall have a minimum vertical separation distance of 18 inches with a minimum cover of 36-inches measured from the crown of pipe to grade in road shoulders, or minimum cover of 30-inches measured from crown of pipe to sub-grade in streets. The preference is for the water main to be located above the stormwater system piping. Where a water main and a stormwater system piping cross and the vertical separation is less than 18 inches when the waterline crosses over the stormwater piping, the following measures are allowed: (i) If under pavement and there is 30-inches of cover to road surface with 6 to 12-inches of separation between pipes, use ductile iron pipe for the Commented [JM2]: 15A NCAC 18C.0906 Town of Lillington Detailed Water Specifications Page 40 Town of Lillington Detailed Water Specifications Page 40 water main with an excavatable flowable fill cradle that meets or exceeds NCDOT specifications at the stormwater pipe crossing. (ii) If cover is less than 30-inches to road surface and stormwater pipe is less than 24-inches in diameter the water line may be located under the stormwater piping. (iii) Water lines that cross and run beneath storm drainage pipes that are greater than or equal to 24-inch diameter shall be installed as restrained joint pipe and enclosed in casing pipe extending a minimum of 5-feet from the outside walls of the storm drainage pipe. (iv) Water lines that cross and run beneath streams or creeks shall be installed as restrained joint pipe and enclosed in casing pipe extending a minimum of 5-feet from the edge of bank and with a minimum cover of 5-feet. (v) Other scenarios will be addressed on a case-by-case basis and may require steel casing pipe under stormwater piping. p. Railroad crossings shall be made following all precautionary construction measures required by the railroad officials. q. All water crossings under the state system roads shall be made in accordance with the requirements of the NC DOT as defined in their encroachment permits. r. Where conditions are, in the opinion of the Town of Lillington Inspector, unsuitable for laying pipe because of weather or trench conditions, the contractor shall be required to cease work until permission is given by the Town of Lillington Inspector for work to commence again providing such conditions have been corrected. 14.15. REACTION BLOCKING a. All fittings or components subject to hydrostatic thrust shall be securely anchored by the use of concrete thrust blocks poured in place, unless otherwise directed by the engineer. b. Material for reaction blocking shall be transit-mixed concrete. This concrete shall have a twenty-eight day compressive strength of 2500 psi. Any metal used to resist thrust which is not encased in concrete shall be “hot dipped” galvanized. 15.16. BACKFILLING PIPE a. Ductile iron pipe shall be backfilled with suitable native material. No rocks, boulders or stone four inches or larger shall be included in the backfill for at least two feet above the top of the pipe. Town of Lillington Detailed Water Specifications Page 41 Town of Lillington Detailed Water Specifications Page 41 b. All backfill shall be compacted in six-inch lifts measured from the pipe foundation upward. Backfill for roadway shall be compacted to at least 95% of maximum soil density in those areas where the supporting capacity of the soil is of prime consideration. Any tests shall be conducted at the direction of the Town of Lillington Inspector, and the cost of such tests will be borne by the contractor. The contractor shall then be required to submit satisfactory evidence that his ditch compaction meets the specifications. c. Deficiency of backfill material shall be supplied by the contractor where this deficiency results from any cause other than rejection of unsuitable backfill material (other than rock) by the Town of Lillington Inspector. In cases where the Town of Lillington Inspector directs, the contractor shall dispose of unsuitable backfill material and provide suitable backfill material. d. Where excavated material has been rendered unsuitable, either before or after excavation, by inclement weather or type of material, the contractor must correct the moisture or furnish replacement backfill material. e. Backfilling shall not be allowed, except with permission of the Town of Lillington Inspector. When a ditch is flooded or the weather is unsuitable, the contractor shall not backfill unless permission is given by the Town of Lillington Inspector. No backfilling with frozen material shall be allowed. f. 16.17. SETTING VALVES AND VALVE BOXES a. Valves shall be set at locations shown on the plans with care being taken to support the valve properly and to accurately position the valve box over the operating nut of the valve. Where pavement is existing, the box shall be adjusted to finished street grade and a concrete pad two-feet square and six inches thick shall be poured around the box two inches from the top of finished grade. When valves are located in street rights-of-way, but out of pavement, the boxes shall be adjusted to finished grade and a concrete pad two-feet square and six-inches thick shall be poured around the box one-half inch from the top. When valves are located outside of street rights-of-way, the boxes shall be at finish grade, and a concrete block two- feet square and six- inches thick shall be poured around the box at grade line. Valve locations out of street rights-of-way shall be marked with a concrete valve marker. The exposed portion shall be placed so that a valve-operating tool has free operation. b. When a tapping sleeve and valve are being used, the valve, sleeve and machine assembly shall be air tested to hold at 200150 psi for a five-minute duration in the presence of the inspector prior to drilling or tapping the main. All tap coupons shall be given to the Town of Lillington inspector. The valve shall be in the closed position during the testing.

Flush the main (all flush water shall be de-chlorinated using methods acceptable to Formatted: Font: 13 pt Formatted: Space Before: 0 pt Town of Lillington Detailed Water Specifications Page 46 Town of Lillington Detailed Water Specifications Page 46 the Town of Lillington Public Works Department); g. Sample for the bacteriological tests; (contractor’s expense) and h. Water mains shall be placed into service within 48 hours of meeting bacteriological analysis requirements and after receipt of the Engineers Certification. If no activity is anticipated on a water main for the first 30 days after it is placed into service, the contractor shall notify the Town of Lillington Public Works Department at 893- 3607. 27.28. PIGGING a. All new mains with gate valves must be pigged with a polyethylene "pig", 5#/cubic foot density at the conclusion of installation. b. The Contractor shall clean all new water mains installed in this project by using a flexible polyurethane swab (“pig”). The pig shall be of 5lb/cf density polyurethane of the proper size for the water mains being cleaned. The pig shall be inserted into the first section of pipe and shall remain there until construction of that line segment is completed. Cleaning shall be accomplished by propelling the pig down the water main by system pressure to the exit point as determined by the Contractor this process shall be observed by the project inspector. After the pig exits the pipe, flushing shall be performed until the water is completely clear and the turbidity level is less than 1.0 NTU. c. Cleaning of water mains with diameters larger than 12 inches or water mains that utilize butterfly valves shall be performed in the same manner excepting that the Contractor will be required to pig the main from valve to valve or in a manner acceptable to the Engineer and the Owner. 28.29. HYDROSTATIC TESTS a. All main installations including private distribution and fire lines to the buildings shall be pressure tested between each main line valve. b. The Contractor shall test in accordance with AWWA C600-99 (DIP) or AWWA C- 605 (PVC), but with a maximum allowable leakage of 0.096 gallons per inch diameter of pipe in accordance with paragraph 28.f. below. All visible leaks shall be repaired regardless of the amount of leakage. c. A section of line that is to be hydrostatically tested shall be slowly filled with water at a rate which will allow complete evacuation of air from the line. Once the line is full, it shall be blown off at a minimum of 2.5 FPS to flush and remove any debris. Hand pumps shall not be used for the pressure testing of water mains. Taps used for Formatted: Font: 12 pt Formatted: List Paragraph, Indent: Left: 0", First line: 0",Space Before: 0 pt, Tab stops: Not at 1.1" Town of Lillington Detailed Water Specifications Page 47 Town of Lillington Detailed Water Specifications Page 47 testing purposes shall be removed after testing and repaired using a stainless steel full circle repair clamp. d. The line shall be tested to a pressure of 200 psi as measured at the highest elevation of the line for a duration of 2 hours. The pressure gauge used in the hydrostatic test shall be calibrated in increments of 10 psi or less. The pressure gauge shall be liquid-filled and indexed for an operating range of 300-psi or less with a minimum dial size of 3-1/2 inches. At the end of the test period, the leakage shall be measured with an accurate water meter. e. All visible leaks are to be repaired regardless of the amount of leakage. The construction inspector inspector may require pressure tests to be performed in smaller segments to determine if there is a problem with a particular section of waterline. No chlorine dosage will be allowed in line during testing. f. For the maximum allowable leakage rates use the following equation: 𝐿𝐿=𝑆𝑆 ∗ 𝐷𝐷 ∗ √𝑃𝑃148,000 L = allowable leakage (gallons per hour) S = length of pipe tested (feet) D = nominal diameter of pipe segment tested (inches) P = test pressure (pounds per square inch) g. Failure of the water main to comply with the above acceptable leakage rate, shall require the contractor to replace any defective materials to insure a watertight installation. If it is deemed that the existing blowoff valve is the cause of failure, the party responsible for the water main extension shall also be responsible for adding a valve at that location and abandoning the existing valve. After any inadequacies have been corrected, the leakage rate will again be tested. This test shall be repeated until that portion of main is brought to compliance with the permissible leakage rate. h. Prerequisite conditions for inspection prior to testing shall be as follows: 1) Hydrants shall be properly located, operable, plumb and at correct elevation. 2) Valves shall be properly located, operable and at correct elevation. Valve boxes or manholes shall be centered over operating nuts, and the top of the box or manhole shall be at proper elevation. 29.30. CHLORINATION a.

BACTERIOLOGICAL SAMPLING a. Free residual chlorine after twenty-four hours shall be at least 10 ppm, or the Public Works Department or Engineer will require the lines be re-chlorinated. b. Mains will be flushed with a blow-off assembly of sufficient size to effectively clean the main. Flushing of lines may proceed after twenty-four hours, provided the free residual chlorine analysis is satisfactory. Flushing shall be continued until chlorine returns to normal level. In times of water shortages or distribution main problems, the flushing operation may be delayed. The Public Works Department shall determine when flushing is allowable. The contractor shall advise the inspector prior to the chlorination and flushing so that the inspector can advise the Public Works Department of the construction location, size and length of mains. All tests will be done in the presence of an inspector. Flushing will be for short duration. Sufficient precautions must be taken to the satisfaction of the inspector to ensure that the impact of the water is absorbed and the water is conveyed without erosion or property drainage. All flush water shall be de-chlorinated using methods acceptable to the Town of Lillington Public Works Department. c. After flushing is completed, the Public Works Department (or their designee) shall collect bacteriological analysis samples for each section of pipe between main line valves. Sample point locations shall be determined by a representative of the engineer or owner. d. A custody seal shall be placed on each set of bacteriological bottles. A chain of custody form must be completed for sample set(s) collected and must be delivered along with the sample(s). In accordance with 15A NCAC 18C.1001, a state approved laboratory will perform the bacteriological analysis. e. Samples will be accepted between 8:00 AM and 12 NOON and 1PM and 3:30 PM Monday through Thursday, excluding holidays. Special arrangements may be made for samples to be accepted outside of this time frame by calling the laboratory in advance. f. In the event that two successive bacteriologic tests fail, that section of the main shall be re-chlorinated by the contractor and new tests performed prior to moving to the Formatted: Indent: Left: 0.61", No bullets or numbering Town of Lillington Detailed Water Specifications Page 50 Town of Lillington Detailed Water Specifications Page 50 next section of main. 31.32.

ITEM SUMMARY Monthly reports covering administrative and department activities, financial summaries and public utility usage information RECOMMENDED ACTION Receive information and direct staff, if applicable. AGENDA ITEM #3 CAPITAL PROJECTS UPDATE SCIF Grants Downtown Facilities Stewart, Inc. is continuing to work on the construction drawings for Downtown. Staff has received cost estimates from Duke Energy for relocation of utilities. The Town has entered into a contract with Duke Energy including a non-refundable deposit of $90K. This will provide the Town with the actual cost for construction for underground utilities. Staff are continuing to work closely with Ducke Energy and Pike to work through construction plans. McAdams is working on the final adjustments to the stormwater infrastructure. Once completed Stewart will incorporate them into the Downtown construction plans. The surveyor has completed the additional requested survey work for Duke Engergy. Duke Energy has submitted preliminary plans for underground utilities. Pike Engineering is working to coordinate underground utilities and conduit for pedestrian and roadway lighting. Pike Engineering is doing both the roadway lighting and the parking lot lighting. Stormwater Resiliency Funds Staff was notified that the State allocated $3.5 million for Stormwater infrastructure improvements and stream restoration, to provide more efficient stormwater management and flood resiliency. Project components will include stormwater management, replacing undersized culverts, and stabilizing streambanks to improve flood resiliency. Staff has received all of the funding to begin the project. Projects: 1. Downtown Stormwater Improvements • Design construction documents have been submitted to the Town and are currently under review. • Consultants are coordinating with the railroad RJ Corman to put in an additional crossing. 2. Duncan Street • Duncan Street is complete • As-builts and CCTV will also be completed at project close out 3. Railroad Crossing • Began Final Design and construction documents. McAdams will provide preliminary plan set to the Town for review before submitting to RJ Corman. • Ongoing coordination with RJ Corman (Railroad) for encroachment documentation and permitting for working within their R/W. Working with RJ Corman is difficult and communication is excessively slow. 4. 13th Street Reservoir • McAdams is recommending upsizing the northernmost culvert crossing on S 13th Street to dual RCBC box culverts to eliminate roadway overtopping for the 10 and 25-Year design storms. Although this recommendation is a slight deviation from the 15’W x 6’H RCBC, which is listed as the preferred design alternative (#2) in the previous Town of Lillington Stormwater Assessment, it will better maintain existing stream geometry and lend to more feasible construction and procurement of materials. • Staff has reviewed and provided comments on 60% CD set • Working towards obtaining 401/404 permitting • Easement acquisition will be necessary for completion of the project. ***During Hurricane Debby Golden Leaf Application Stormwater Harnett Street Project Description: The proposed storm drainage improvements would include removal and replacement of existing storm drainage pipe, ranging from 15” RCP to 30” RCP, and removal and replacement of storm drainage structures, including catch basins, drop-inlets, storm drainage manholes, and storm drainage headwalls. The proposed storm drainage infrastructure will effectively capture storm runoff, convey stormwater efficiently inside public right-of-way, and increase the level of service of the storm drainage system. In addition, private storm drainage infrastructure would be relocated to the Town Right-of-Way to allow for easier access for future maintenance and inspections. The probable cost of this project is $1.3 million, the Town has agreed to contribute $250,000 to the project. The Golden Leaf Grant Agreement was approved in June. A project ordinance confirming the Town’s financial contribution is slated for approval on the consent agenda for the August Regular Meeting. North Carolina Emergency Management Transportation Infrastructure Resiliency Grant The Town was awarded a grant from the North Carolina Emergency Management Transportation Infrastructure Resiliency Program for $790,000. Staff issued a Notice of Award to Narron Contracting, Inc. and the project is currently under construction. Construction is now complete and staff met with the North Carolina Department of Emergency Management July 25th for a final site visit to close out the project. As-builts and CCTV will also be completed at project close out with the contractor. There are also some areas that staff has requested estimates from the contractor to construct some additional stormwater infrastructure on the section of Duncan Street that was only supposed to be paved. The project came in under budget when completed and the non-expended funds will cover most of these expenses for the additional work requested. Fire Station #3 The Town staff has received their third schematic layout of the Fire Station and are continuing to work closely with Bobbitt. Below is the layout of the interior of the fire station. Staff is meeting with Bobbitt August 15th to discuss the proposed interior finishes for the station. The station will be ready to bid and finance in the coming months. ARPA S.L. 2022-74 Appropriated Projects All documentation was submitted to the State to fund the Hwy 210 sewer line expansion and Southern Regional Sanitary Sewer/Poorhouse Creek installation of new sanitary sewer interceptor and regional pump station. The total allocation was $9,250,000. Staff has received the offer and acceptance letter from the Department of Water Infrastructure. a. Hwy 210 Sewer line Project Temple Grading signed the NTP August 14, 2023. Construction has begun and is on-going. The contractor is continuing to install the 8-inch force main along NC Hwy 210 North and is nearing completion. The pump station site clearing has been completed and the contractor is expected to begin installing the pump station wet well this month. Pump station construction is scheduled to be complete by the end of July. The installation of the gravity sewer will start in August. The contractor has presented two change orders to the Town; changer order 1 for the additional contract time (89 calendar day increase) due to the Crested Iris design change to connect to the HRW collection system and outside agency concurrence, change order 2 is for the cost to complete the work at Crested Iris Drive to make the HRW sewer connection as demonstrated on the latest design drawings ($156,801.56 and 30 calendar day increase to contract time). The change orders have been approved by the state and the Town of Lillington. b. Poorhouse Creek Meyers Engineering will be submitting to DWI for a sewer permit in the coming weeks. Contract documents have been reviewed by staff and comments have been addressed. Easement acquisition has begun. The project will go out for bid in late August or early September. DWI has approved the project and construction plans. LASII Grant Staff submitted the LASII grant application October 2, 2023 requesting $500,000 to develop and implement a new stormwater utility to provide a predictable, equitable and ongoing funding source for its stormwater program. The activities that the Town seeks to accomplish with the funding that the utility will provide include: • Increasing the flood resiliency of the transportation system in and through the Town; • Funding stormwater Capital Improvement Projects (CIPs) to address stormwater quantity and quality issues; • Handling critical maintenance needs and operations; and • Meeting planning and implementation needs. The scoping document was approved by DWI, the grant agreement and the acceptance of funding resolution is slated for approval on the consent agenda.
