Since the system relies only on purchase water for supply, no process water is used. Reuse water is used at the WWTP for process water. The Town tracks all water for town use, such as town irrigation water, facilities, parks, and flushing water. Flushing water was estimated at 0.001 MGD based on prior year's submittals.

The Town's Finance Department has been re-evaluating all account use types, resulting in a decrease in Commercial use in 2024.

The Town’s contract with Harnett County is for a maximum day use of 10 MG. However, the LWSP form does not property represent this as a max day
value, but shows it as an average day value of 10 MGD within its calculations, thus overstating the available supply. During the Jordan Lake Allocation
process, we worked with the State to develop a representative average day value for this contract. We chose to use a max month value of
approximately 6.7 MGD, which is represented throughout the LWSP.

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 49 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?   The Town currently enforces a Water Conservation and Water Shortage Response ordinance. The Town also has installed a water reuse system to offset potable water demands. Lastly, the Town has an active leak detection program.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   The Town participates in regional water supply planning efforts, including the Jordan Lake Partnership, Wake County Water Partnership, and Triangle Water Partnership. Also, the Town maintains relationships with regional water suppliers such as Harnett County and the City of Sanford.

How does the water system intend to implement the demand management and supply planning components above?   For demand management, the Town continues to promote the use of its reclaimed water system, growing connections to the system. For water supply planning, the Town performs routine planning for water supply to identify the timeframe of future needs and required funding for such needs.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, The Town continues to participate in regional water supply planning, primarily through the Jordan Lake Partnership and the Triangle Water Supply Partnership.

What major water supply reports or studies were used for planning?  Major water supply efforts and studies used in planning include the Jordan Lake Water Supply Allocation studies, the Triangle Water Supply Partnership Regional Water Supply Plan and Interconnection Model, and the Regional Water and Wastewater Infrastructure Concept Plan (NCDEQ).

Please describe any other needs or issues regarding your water supply sources, any water system deficiencies or needed improvements (storage, treatment, etc.) or your ability to meet present and future water needs. Include both quantity and quality considerations, as well as financial, technical, managerial, permitting, and compliance issues:   There are no additional needs at this time, beyond those listed in this form.
