PWC performs unidirectional flushing of all our mains through our hydrants on a five-year cycle. PWC coordinates with the area Fire Departments to inspect and repair hydrants annually.

All valves are inspected and operated during the unidirectional flushing program. All valves 16” or larger are exercised on an annual basis.

PWC utilizes various points of mechanical and electronic leak detection devices throughout the system to pinpoint any suspected leakage. Distribution staff utilize field spectrophotometers to determine whether leaks result from leaks or groundwater sources.

We also utilize the following incentive programs to encourage water conservation from our customers:
• Energy Star Clothes Washer - $30 per replacement
• Energy Star Dishwasher - $30 per replacement
• High-Efficiency Toilet – ¼ of the monthly charge or $75 per unit
• Rain Sensor – up to $50 per installed unit

PWC utilizes the following rate structures:

• “Flat or Fixed” rate is used as a temporary rate
• “Increasing Block” is utilized for residential and irrigation customers
• “Uniform” is used for non-residential, non-residential irrigation, large water customers, and hydrant connections

PWC does have an interconnection with Harnett County via the Town of Spring Lake at Ft. Bragg systems. However, this interconnection has little value in meeting the daily requirements of PWC in case of an emergency. There are no other systems near either the pumping or line capacity to supply PWC’s customer base with water, even on an emergency basis.

The system annual service population is the number of metered residential connections multiplied by the “persons per household” (pph) figures derived from the current US Census Bureau “Quick Facts” data for the City of Fayetteville and Cumberland County. The "pph" figures have trended downward in recent years; the 2025 service population is slightly lower than the previous year, despite new customers being added.

Totals for residential and commercial include irrigation usage.

Brettonwood Hills: no more than 864,000 per month
Fort Liberty: no more than 8 MGD (PWC began supplying 50% of all Ft Liberty water in 2010)
Hoke County: no more than 42,000,000 per month
Kelly Hills: no more than 486,000 per month
Spring Lake: 13,000,000 per month*
Stedman: no less than 1,035,000 and no more than 5,000,000 per month

NOTE: PWC is working with the Town of Stedman to determine the source(s) of discrepancy between PWC’s 2025 water supply sales to Stedman, reported as 0.0670 MGD, versus Stedman’s 2025 water supply purchase from PWC, reported in their 2025 LWSP Update (Provisional) as 0.1023 MGD.

PWC has reported its Cape Fear River available raw water supply as 85.8 MGD (i.e., 42.9 MGD allocated to each of our two intakes). This value is based on a USGS study titled “Low-Flow Characteristics and Discharge Profiles for Selected Streams in the Cape Fear River Basin, North Carolina”, through 1998, in which the historical 7Q10 flow in the Cape Fear River at Fayetteville was estimated as 625 CFS or 404 MGD. Therefore, 80.8 MGD represents 20% of this 7Q10 value. Combined with the additional 5 MGD available from Glenville Lake, PWC has an estimated available Cape Fear River supply of 85.8 MGD. During Round 4 of the Jordan Lake water supply allocation process, DWR instruction to applicants with run-of-river sources was that available supply is assumed to be 20% of the 7Q10 flow as determined using the base-case scenario of the appropriate river basin hydrologic model. At Lock & Dam #3, the basin model (for the 2045 Baseline scenario) showed 7Q10 of 236 MGD, and 20% of that 7Q10 is 47.2 MGD. PWC requested a Jordan Lake allocation since its projected future demands are well over the calculated 47.2 MGD. However, the State did not grant this request and indicated in its Round 4 decision documentation that an approach using PWC net withdrawals (i.e., factoring in wastewater return flows) to compare against 20% of 7Q10 would mean far more available Cape Fear River supply for PWC.

According to Appendix B “Water Availability Behind Lock and Dam #3” of DWR’s December 2016 Cape Fear River Surface Water Supply Evaluation, Fayetteville PWC may be able to withdraw 174.5 MGD from behind Lock & Dam # 3, on an average day basis, without reducing the model-generated 7Q10 flow by more than 20 percent. Because this estimate is based on net withdrawals it depends on Fayetteville’s ability to maintain a similar ratio of wastewater discharges to water withdrawals in the future. On April 4, 2017, the EMC, in its final decision inserted this same Appendix B into DWR’s Round 4 Jordan Lake Water Supply Allocation Recommendations.

Minimum flow of 4 CFS must be maintained downstream of the Glenville Lake dam.

Little Cross Creek feeds four impoundments, which have a total capacity of 250 Million Gallons. This was considered by NCPWS as off-line storage when the P.O. Hoffer WTF was granted an uprating.

PWC has completed the design for a 16 MGD treatment capacity expansion at the PO Hoffer Water Treatment Plant (from 32 MGD to 48 MGD). The projected date for beginning construction is the year 2027 unless system demand dictates beginning sooner.

The design for the Rockfish Creek WRF Phase 3 Expansion project (from 21 MGD to 28 MGD) is complete, with construction tentatively scheduled for FY28. PWC has on record an Environmental Assessment (EA) to expand the current rated capacity of 21 MGD to the new permitted 28 MGD for future planning purposes.

Fayetteville PWC owns the Cliffdale West wastewater system, i.e., gravity lines and lift stations, but does not monitor the individual flow. Fayetteville accounts for the flow from Cliffdale West in their total discharge.

The wastewater discharge from NORCRESS includes the combined flow from collections systems for the Town of Wade, the Town of Falcon and the Town of Godwin.

Sales projections for PWCs three major bulk water customers are provided in the above table. The estimated figures represent the relative increase in sales over the respective 10-year reporting periods and are based on total demand data taken from those systems most recent available LWSP Update and the current trending for percentage of total system demand provided by PWC as follows:

(1) Fort Bragg MB (50%)
(2) Hoke County Regional Water System (32%)
(3) Town of Stedman (100%)
