In 2026, BCPU will begin purchasing additional raw water from LCFWSA, and increasing finished water output volume based on need.

PCU will purchase 5 MGD of raw water from BCPU in 2027.

The county is pursuing potable reuse and support for modeling of the CFR basin for the opportunity to address and expand the safe yield in the lower Cape Fear River Basin at Lock and Dam #1

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 84 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.    NA

Are there other demand management practices you will implement to reduce your future supply needs?   N/A

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   Groundwater and surface water sources are being considered in the southwest portion of the County.

How does the water system intend to implement the demand management and supply planning components above?   The County would contract with a firm specializing in water supply development, funding assistance, and permitting.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, We work with the Lower Cape Fear Water and Sewer Authority to develop a raw water allocation for Brunswick County.

What major water supply reports or studies were used for planning?  An engineering firm was used to develop recommendations.

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:   The Northwest WTP is nearing completion of an expansion and modification to treat for PFAS removal and meet growing water needs of our community.
