Demand v/s Percent of Supply

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 55 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.    CFPUA continues to conduct annual water loss audits and investigate system optimization strategies.

Are there other demand management practices you will implement to reduce your future supply needs?   CFPUA's Water System Master Plan update is in the final stages via our engineering department and seeks to guide how we will address future needs as identified to meet customer demand projections.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   Optimization of existing groundwater emergency wells in key system support areas. Master planning for both upgrading and adding production wells to provide additional capacity to the Richardson WTP and overall integrated system. Extensive interconnects allow the integrated system to be supported by all supply sources in a more reliable and resilient manner. The Lower Cap Fear Water and Sewer Authority as well as purchase partners (Brunswick, Pender, CFPUA, commercial) are investing resources into redundancy and resiliency along the length of the common raw water transmission mains which are underway this calendar year (2026).

How does the water system intend to implement the demand management and supply planning components above?   Funding and design of additional sources will be through CFPUA's Capital Improvements Plan as required to meet anticipated demands. The demand-to -supply ratio in the Lower Cape Fear Water and Sewer Authority (LCFWASA) - Kings Bluff Local Water Supply Plan (LWSP) is currently above 80% because available raw water supply is full allocated to the existing customers and partners (i.e. Brunswick County, CFPUA, and Pender County). Based on a 7Q10 calculation, the Lock & Dam No. 1 safe yield total is 106 MGD. LCFWASA safe yield is 96 MGD with CFPUA allocated safe yield of 10 MGD. Even so, the currently projected demands of all partners - when totaled - remains below the 80% of available raw water supply for the foreseeable future (i.e. 2050). Furthermore, all the partners have agreed not to exceed the demands currently projected in their LWSP, without notice to NCDWR, even though these amounts may remain less than what LCFWASA - Kings Bluff is obligated to sell them. However, should projected water demands of the partners increase to such amounts where the demand-to-supply ratio in the LCFWASA Kings Bluff LWSP exceeds 80%, a long-term water supply plan to address future demands would be necessary, per statutory requirements, before NCDWR could approve the LWSP.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, Yes, in 2020, CFPUA, LCFWASA, Brunswick, and Pender Counties implemented a Raw Water Supply Emergency Management Plan to have a unified protocol for water shortage response planning and reporting during droughts, water emergencies, and other potential raw water supply challenges.

What major water supply reports or studies were used for planning?  Each partner utilized their existing water shortage and emergency response plans to create a unified plan.

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:
