Overall, there are 610 total customers with 420 in town and 190 outside of town. The in town customers breakout into 339 residential and 81 business/industrial and the out of town customers into 190 residential and 12 businesses. Although there are no accurate records available to identify the date of the start of the distribution system, it is generally believed to have begun in the 1930's. The town currently has approximately 91,400 lineal feet of distribution lines ranging from 1 % inch to 12 inch and made with various types of materials that were current during the time of various phases of development of the system. Sewer Svstem Most of the town's wastewater collection system was constructed in the 1940's and the wastewater treatment plant was constructed in 1986 with a permitted capacity of 0.280 million gallons per day (mgd). The collection lines were construction with vitrified clay pipes with replacements in 1988 and recently being built with PVC piping. The collection lines current has approximately 60,695 lineal feet (LF) of 8-inch pipes and there are two outfall lines: 2,910 LF of 10-inch outfall and 1,150 LF 12-inch outfall. The town's sewer system service area is shown on the Water and Sewer Service Areas Map, which includes the town as well as the areas outside of town. Overall, the town serves 505 customers with 393 customers in town and 112 customers outside of the town limits. The in town customers are divided into 318 residential and 75 businesses and the out of town customers are divided into 106 residential and 6 businesses. TOWN OF LITTLETON CAPITAL IMPROVEMENT PLAN The following is a summary of the conclusions and recommendations for both systems: Sewer System "The wastewater collection system for the Town of Littleton is in need of major renovation work to eliminate overflow and runoff of ray sewage to the surface waters, reduce infiltration and inflows, and reduce or eliminate emergency maintenance and repairs which are necessary at the present time to keep the system operational. The sewage treatment plant is generally providing good treatment. The effluent consistently meets or exceeds NPDES Permit limits. However, there is no emergency power. The greatest deficiencies are at the sewage pumping station. Pump station No. 3, West Littleton needs to be completely rebuilt or replaced. Pumps at this station sometimes run 24 hours per day. Overflows are likely during peak flow periods. Lesser upgrades are needed of the other 5 pump stations. These include provision of emergency power, auto dialers and miscellaneous other repairs. Alternate No. 4 includes pump station upgrades, emergence power installation and point repairs to gravity sewer system. Estimated cost of this alternate is $513,875.00." Water System "To correct deficiencies identified in this report, the following are recommended in priority order. 1. Constructed a six inch water main on Mosby Avenue forming a loop from North Main to Mulberry Street. Provide fire hydrants as needed. Estimated Cost $: 54,700.00 2. Employ a utility locating company to accurately locate all underground water lines and lost valves, determine which services are connected to old 1 Y2 inch diameter and smaller lines and which lines need to be abandoned. Use this data to prepare and accurate as -built water distribution map. Estimated Cost $: 50,240.00 3. Abandon all old 1 %inch diameter and smaller lines, reconnect services to newer, larger lines, raise buried valves to grade and make them operable, install new valves where needed and replace non operable fire hydrants. Estimated Cost $: 242,000000 4. Construct a new 8 inch diameter main from Bacon Road along Highway 158 to elevated tank as a back up supply line and to encourage development along Highway 158 as an economic boost to the Town. Estimated cost $: 18810006001, 12 TOWN OF LITTLETON CAPITAL IMPROVEMENT PLAN 2. Sanitary Sewer Collection System Evaluation A. Gravity Collection System The tOWn's collection (gravity and force mains) is approximately twelve miles in length. Most of the collection system is vitrified clay that was constructed in the 1940s. Listed below is the collection system: 60695 LF 8-inch 2910 LF 10-inch - outfall 1150 LF 12-inch — outfall A portion of the system was dug and replaced in 1988 EPA Project No. 3370589-02. That project addressed the following: 1150 LF of 12-inch outfall 2910 LF of 10-inch outfall 4000 LF of 8-inch main line (PVC) 4400 LF of pressure grouting B. CCTV Inspections In February 2003, the Town of Littleton employed JCB Environmental to clean and CCTV a portion of its sanitary sewer collection system. The total footage of 8-inch sanitary sewer line cleaned and CCTV was 1887 LF. This represents 0.0291 % of the town's total system. The total system consists of 64,775 LF. There were a total of nine line segments CCTV inspected. Only one line segment could be totally inspected. The other eight line segments were abandoned because of protruding taps, collapsed pipes, and severe root intrusion. Please review the attached CCTV inspection reports. Please note that the town allotted $3000 to clean and CCTV inspect a portion of its sanitary sewer system. The town expected to clean and CCTV more than the 1887 LF, but the severity of the problems significantly reduced the amount of line that could be reviewed. Several other areas of town need to be cleaned and CCTV inspected before a final action plan of rehabilitation can be determined. C. Major Problem Areas CCTV inspection revealed the major problem areas were Ferguson Street, Halifax Street, Spring Street and Mosby Street. The problem with Mosby Avenue was its manholes. 14 TOWN OF LITTLETON CAPITAL IMPROVEMENT PLAN The majority of the older brick manholes are in poor to fair condition. The type of rehabilitation for these manholes will be determined based on the type of rehabilitation of the sanitary sewer system line segments. A potential rehabilitation could be either a poly triplex liner, a cement coating or total replacement depending upon the condition of each manhole at the time of rehabilitation. Manhole construction type are as follows: approximately 53 precast; and approximately 140 brick. Dye Testing Dye testing has been performed in the sanitary sewer collection system and the local ditches. The dye testing was done to try to locate areas of inflow. The dye testing was done using fire hydrants as flush water and it was also done during periods of heavy rainfall. Testing results revealed several areas of inflow. These areas were mostly broken clean outs, storm water cross connections, and broken sanitary sewer lines. Please review the attached map, which details the dye testing areas and resulting problems. 3. Lift Station Evaluation The Town of Littleton has five sanitary sewer lift stations that it owns and operates. There are two additional privately owned lift stations that deliver wastewater to the town's WWTP. Please note that none of the lift stations have backup or emergency power. All three of the main lift stations — West Littleton, Enon, and Church Street were designed in 1957 and constructed shortly thereafter. These lift stations are still in their original condition. Only as needed maintenance has been done to each lift station. These lift stations have reached their useful life and need to be replaced. These lift stations have been a continued source of overflow violations. Because of the large amount of overflows at each lift station, it is extremely difficult to analyze the inflow and infiltration for the entire sanitary sewer collection system. Overflows have been documented many times at each lift station during and after times of heavy rainfall. The actual amount of discharge has not been determined because of the limited data collection equipment. The bypass/overflow for each station is estimated below. The lift stations and their condition are listed below: A. West Littleton Lift Station This lift station consists of a wet pit/dry pit system. The wet pit is for the influent; the dry pit is for the pumps. This lift station is almost totally deteriorated. This system was originally installed with an 8-inch bypass/overflow that allows the flow to be bypassed during times of heavy inflow and infiltration. Please review the attached plans, which details the original construction. An estimated bypass flow has been calculated based on the orifice size and head elevation in the manhole. This bypass flow eventually ends up in the Lake Gaston watershed. These bypass opening have been plugged, but the flow during heavy inflow and infiltration times now overflows at the manhole on the inlet side of the lift station. This overflow continues to the ditch that was described above. TOWN OF LITTLETON CAPITAL IMPROVEMENT PLAN There is no fence around this system. There is no warning system or telemetry. There is no emergency backup power or switchgear system. This system needs to be totally replaced and brought up to current NCDENR standards. D. Highway 158 Lift Station This system consists of a small submersible type pump system. This system receives flow from a few houses and operates well. This system does not have a bypass/overflow port. There is no fence around this system. There is no warning system or telemetry. This system needs to be brought up to the current NCDENR standards concerning the fence, alarm, telemetry, etc. E. McIver School Lift Station This system consists of a small submersible type pump system. This system receives flow from a few houses and a local school. This system operates well. This system does not have a bypass/overflow port. There is no fence around this system. There is no warning system or telemetry. This system needs to be brought up to the current NCDENR standards concerning the fence, alarm, telemetry, etc. 4. Inflow Evaluation The Town of Littleton does not currently monitor rainfall amounts. Therefore no local data is available to evaluate inflow. It is recommended that a rainfall gages be installed at convenient locations within the collection system. The town `s ORC should read and record rainfall on a daily basis for future use in evaluation of inflow and infiltration. In the absence of local data, rainfall records were obtained from the National Weather Service Climatic Data Center for the nearest stations to the Town of Littleton. The nearest stations were outside of Warrenton, N.C. (Arcola Station) and Roanoke Rapids Station. It is difficult to estimate the amount of inflow in the system for two reasons. One —the overflows stated above in the lift station section do not allow a significant amount of inflow from these areas to enter the WWTP where measurements can be made. Two the inflow chart at the WWTP is only calibrated to 280,000 gpd. There are no strip charts or data recording to capture the actual maximum or minimum flows. The readings from the daily log are taken at 8:00 AM and are not truly average, maximum or minimum readings. There have been several occasions where the flow has reached the limits of the chart recorder. The chart recorder is only calibrated for 280,000 gpd. The actual flow peaks at these times cannot be determined. Several of these peak inflow events have been included with this report. The associated rainfall data has also been included. This information has been included to demonstrate the severity of the inflow problem. Please note that a 1-inch rainfall event will create a flow at the WWTP in excess of 280,000 gpd. TOWN OF LITTLETON 3. Lining CAPITAL IMPROVEMENT PLAN As also stated above, lining might be a viable alternative to some of the sanitary collection system. Recommendations will be made based upon the CCTV inspections. Estimated cost: $5,893,717, 4. Pipe Bursting Using pipe bursting as an alternative will also depend upon the CCTV inspections. 5. Replacement of Three Lift Stations Replacement of three lift stations is the recommended alternative at this time. Estimated cost: $2,066,494. 6. Expand and Upgrade Wastewater Treatment Plant Expansion or upgrade of the WWTP is not recommended at this time. The current permitted flow rate is adequate for most flow conditions. As discussed above, once the three pump stations are rebuilt and all the inflow and infiltration gets transported to the WWTP, then the system will be evaluated again for possible expansion. Sewer System Recommended Needs Sanitary Sewer System —Action Plan The following projects will be funded by a loan from the Southeastern Rural Community Assistance Project (SERCAP). The town will borrow approximately $200,000 from SERCAP and apply for a $400,000 supplemental grant from the NC Rural Economic Development Center: A. Immediate Needs 1. Replace three lift stations. West Littleton, Enon and the Church Street lift stations need to be replaced to stop the overflows. 2. Repair known inflow problems. Use the smoke test study and the dye testing study to repair the known areas of inflow. Repair of these areas can significantly reduce the amount of inflow to the sanitary sewer collection system. 3. CCTV -inspect critical areas of collection system, approximately 17,000 LF of 8-inch VCP main trunk lines. Initial CCTV inspection revealed major problems with the collection system. A broader area needs to be CCTV inspected to determine the severity of the system. Once the problem 20 TOWN OF LITTLETON CAPITAL IMPROVEMENT PLAN The distribution system consists of the following types and sizes of waterlines: 12 inch Asbestos Cement (ACP) 520OLF 8 inch Asbestos Cement 17800 LF 8 inch Cast Iron 1600 LF 6 inch Asbestos Cement 25600 LF 6 inch Cast Iron 9800 LF 6 inch PVC 7000 LF 2 inch PVC 4400 LF 1 1/2 inch Galvanized 20400 LF The 12 inch ACP is used to feed an out of town customer (nursery). The 8-inch and 6- inch lines are mainly for fire flow and water distribution. The smaller lines are mostly used to supply potable water to residents. In many cases, the larger lines parallel the smaller lines. This is shown on the Water Distribution System Master As -Built Plan in the Preliminary Engineering Report by Mack Gay Associates dated Nov. 18, 2003. 2. Distribution System Evaluation In general, the water distribution and fire demand is adequate for the system. There are some areas that need to be looped to increase flow. As discussed above, careful consideration should be given to the replacement of the ACP lines. 3. System Maintenance Evaluation A considerable amount of the town's maintenance budget is spent on repairing existing deteriorated waterlines. Most of the repairs are made to the smaller diameter lines. As discussed above, the smaller lines need to be abandoned. 4. Fire Flow Data In general, fire flow is adequate throughout the town. There are several fire hydrants that need to be added for the proposed waterlines. There are also several fire hydrants that need to be replaced. A previous Preliminary Engineering Report addressed the fire flows. The fire flow data was confirmed. This information is included in the Preliminary Engineering Report compiled by Mack Gay Associates dated Nov. 18, 2003. TOWN OF LITTLETON CAPITAL IMPROVEMENT PLAN Water Svstem Recommended Needs Water Distribution System —Action Plan Applications will be made to the North Carolina Construction Grants and Loans State Revolving Fund Program and USDA Rural Community Funds to A. Immediate Needs 1. Remove and replace the existing 6-inch and 8-inch asbestos cement pipe (ACP). This ACP was installed in approximately 1973. There are some studies, which show serious health concerns associated with ACP. 2. Abandon the 1'/z and 2 inch diameter lines as repairs are made to these smaller lines. Set up a schedule to abandon the remaining smaller lines on astreet-by-street basis. Service connections should be reconnected only to existing PVC and cast iron waterlines. It is not recommended that services connections be made to the existing ACP waterlines. 3. Install two-way flow meters at the existing Halifax County water main connections. The town is currently reselling water back to the county. These connections are located at the intersection of Ferguson Street and NC Highway 4, and near the intersection of SR 1001 and SR 1300. These connections can be used as a backup water supply if there is a major break in the existing 8- inch line supplying the 300,000-storage tank. This supply would be adequate for drinking water but would not be adequate for fire protection. 4. Construct a 6-inch waterline along Mosby Avenue between North Main Street and Mulberry Street. This will increase the pressure for the Medical Center. 5. Construct an 8-inch backup water supply line to the 300,000-gallon storage tank. This line would along NC Highway 158 from the existing booster pump station B. One to Five Year Plan Applications will be made to the North Carolina Construction Grants and Loans State Revolving Fund Program and USDA Rural Community Funds to: 1.

Upon arrival at a spilUSSO, the dispatched system staff will perform the following: ➢ Determine the cause of the spill/SSO (collection line blockage, lift station malfunction, line break, etc.). ➢ Report findings to Supervisor and identify or request additional personnel and equipment to minimize the effects of the spill/SSO. ➢ Should it be determined the cause of the spill/SSO is not the responsibility of the system, dispatched personnel will; o Take appropriate action to protect public health, property (public and private), and surface water bod5 es from immediate danger. 2. Containment of a spill/SSO will be of utmost priority and will include, but are not limited to, the following measures: ➢ Determine the immediate destination of the spill/SSO (storm drain, water body, ditch, etc.) ➢ Identify and request the necessary personnel and equipment to contain and minimize the effects of the spill/SSO ➢ Take the appropriate, immediate action to contain the spill/SSO 3. Additional measures may be necessary to contain a prolonged spilUSSO. These measures will be determined and implemented by the Supervisor. 4. Clean up of a spilUSSO will be prompt and thorough. The necessary measures will be taken to eliminate any identifiable evidence of the spill/SSO. ➢ If possible, photos will be taken before and after clean up. Photos will be filed with the spill/SSO report ➢ The affected area will be cleaned of any sewage and debris. All materials collected will be properly disposed of ➢ The area will be secured to prevent public contact, until the affected area has been thoroughly cleaned ➢ The spill/SSO site should be disinfected and deodorized, if appropriate ➢ If spill/SSO has affected a surface water body, the NC DWR Raleigh Regional Office will be contacted for specific instructions. D. Overflow Reporting A written report to the NC DWR Raleigh Regional Office is required within five days. The Supervisor will complete the required reports and submit them to the NC DWR Raleigh Regional Office. Additional reporting requirements to the public may be required based upon volume discharged. For accurate reporting purposes, system personnel should gather the following information: Determine if the spill/SSO has affected any surface water bodies Estimate the start time of the of the spill/SSO: o Date/time reported and confirmed by system personnel o Visual observations Estimate the stop time of the spill/SSO: o Date/time the blockage or equipment malfunction has been corrected o Date/time system personnel arrived onsite, if spilUSSO stopped before system personnel arrived ➢ Visual Observations o Estimate the flow rate of the spilUSSO o Estimate the volume of the spill/SSO o Take photos for documentation o Assess damage to public and private property (System personnel will not enter private property to assess damage, unless authorized by the Supervisor) E. Customer Satisfaction To ensure good public relations and customer satisfaction, the appropriate system personnel will follow up with the reporting party.
