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 53 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.    Johnston County has an active reclaimed water system. The County will continue to pursue opportunities to expand reclaimed water use. In addition the County will perform regular water audits and develop a leak detection program.

Are there other demand management practices you will implement to reduce your future supply needs?   The County has year-round mandatory water alternating day watering policy to reduce peak demands.

The County is in the final stages of preparing a revision to our drought management plan.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   We are considering additional connections with neighboring systems for regional solutions and increase resiliency.

How does the water system intend to implement the demand management and supply planning components above?   The County will continue to participate in the Triangle Water Supply Partnership and actively work with neighboring systems to meet regional water supply. We will actively pursue opportunities to expand the use of reclaimed water to supplant potable water uses.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, Johnston County is a member of the Triangle Water Supply Partnership. Together with the other members of the partnership we are working with DWR on a long term water supply plan for the triangle that encompasses both the Neuse and Cape Fear Rivers.

What major water supply reports or studies were used for planning?  Johnston County works with Hazen and Sawyer to prepared a long term water supply 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:   Our new long term water supply plan included using one quarry as storage initially and a second quarry with future expansions. The two quarries combined will provide over 3 billion gallons of storage.
