County(s)% of Service Population
Rowan100 %
What was the year-round population served in 2024?   45,329
Has this system acquired another system since last report?   No

Population based on the number of service connections* (19,289) multiplied by 2.35.

*Population count decrease is attributed to removal of irrigation and other (non-water service) meters from the connection count. Several irrigation meters were found to be mislabeled as domestic while reviewing records for the lead service line inventory; those records have since been corrected. Other meters not included in service connection count are those used at flushing sites and those used to meter sewer-only accounts where a private well supplies drinking water.

The purpose of the above chart is to show a general indication of how the long-term per capita water demand changes over time. The per capita water demand may actually be different than indicated due to seasonal populations and the accuracy of data submitted. Water systems that have calculated long-term per capita water demand based on a methodology that produces different results may submit their information in the notes field.

Your long-term water demand is 51 gallons per capita per day. What demand management practices do you plan to implement to reduce the per capita water demand (i.e. conduct regular water audits, implement a plumbing retrofit program, employ practices such as rainwater harvesting or reclaimed water)? If these practices are covered elsewhere in your plan, indicate where the practices are discussed here.    No changes

Are there other demand management practices you will implement to reduce your future supply needs?   Salisbury has completed an Advanced Metering Infrastructure (AMI) project that has replaced all meters. This facilitates many demand management practices, including detailed water audits, customer side leak detection, targeted water use education and enhanced enforcement of conservation measures.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   None

How does the water system intend to implement the demand management and supply planning components above?   SRU has made customer portals available to view hourly use data for their personal water meter. This allows customers to see a detailed water-use report and can properly make decisions on how to reduce water-use. Technical support to help customers set up their account is available if needed. SRU also has a proactive water leak detection practice where we can investigate small leaks prior to them turning into major issues. This enables us to cut down on water loss, and repair costs of untimely large breaks.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, In 2016, Salisbury helped form the Yadkin - Pee Dee Water Management Group. The purpose of this group is to promote regional water supply planning.

Salisbury Completed a water system master plan as well as the creation of a new calibrated hydraulic model in calendar year 2022.

What major water supply reports or studies were used for planning?  TECHNICAL REPORT: HIGH ROCK DAM AND HIGH ROCK LAKE SEDIMENTATION FLOODING EFFECTS AS ESTIMATED USING HEC-RAS MODELING, City of Salisbury (Salisbury-Rowan Utilities), January, 2006 NUMERICAL SEDIMENTATION INVESTIGATION, YADKIN RIVER, NORTH CAROLINA, Mobile Boundary Hydraulics, February, 2007 HIGH ROCK DAM AND SEDIMENT DELTA FLOODING AND SEDIMENTATION EFFECTS (19272058) ON CITY OF SALISBURY CRITICAL INFRASTRUCTURE, Martin Doyle, February 2007 and FINAL ENVIRONMENTAL IMPACT STATEMENT FOR HYDROPOWER LICENSES YADKIN HYDROELECTRIC PROJECT FERC PROJECT NO. 2197073 YADKIN-PEE DEE RIVER HYDROELECTRIC PROJECT FERC PROJECT NO. 2206030 NORTH CAROLINA, Federal Energy Regulatory Commission, April 2008.
