The contract with Kill Devil Hills and Nags head are much greater than the current demand. It is written in the contract with both Nags Head and Kill Devil Hills that if the facility has exceeded 90% for two consecutive days and the towns have exceeded their allocations, they must pay to add additional treatment trains. Based on the Kill Devil Hills and Nags head LWSP's, their demand will remain less than half of the contract amount through 2060.

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 72 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.     New automated meters are being added with leak detection and notification. This should help stop leaks much sooner to save water at vacant vacation homes, especially in the offseason but during peak season as well.

Are there other demand management practices you will implement to reduce your future supply needs?    New automated meters are being added with leak detection and notification.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   Additional wells and two trains for the Skyco plant are being added. Infrastructure is in place to expand with RO trains as well.

How does the water system intend to implement the demand management and supply planning components above?    No changes

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?  

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:
