Walnut Cove is currently looking to establish an emergency contract with Stokes Co WAu and will be constructing a new well. These options still leave Walnut Cove with the need for additional supply by 2030 when the system reaches >80% Demand as Percent of Supply. As of this time, a specific plan to address the demand exceedance has not been submitted.

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 69 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.    

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

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   

How does the water system intend to implement the demand management and supply planning components above?   

Walnut Cove is currently looking to establish an emergency contract with Stokes Co WAu and will be constructing a new well. These options still leave Walnut Cove with the need for additional supply by 2030 when the system reaches >80% Demand as Percent of Supply. As of this time, a specific plan to address the demand exceedance has not been submitted.

Additional Information

Has this system participated in regional water supply or water use planning?  No

What major water supply reports or studies were used for planning?  Town of Walnut Cove Water System Master Plan, 1999

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:   1. Need SCADA system to monitor wells and elevated storage tanks.
2. Need to elimiate the use of potable water at WWTP to operate chlorinators and sulphonaors.
3. Need to replace all of the AC pipe in the system.
4. Need to install a pressure reducing valve at connection to Stokes Co. Water Authority to prevent our elevated tanks from overflowing.
5. Need to replace approximately 25 fire hydrants in system.
6. Need to replace approximately 100 non-operating valves in the system.
