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.

There are two new 1.25MGD trains and two new wells for Skyco WTP in the 2025 and 2026 Budget years. The two trains are almost completed and are scheduled for start up in April 2025. One well is in the 2025 budget and the second well is in the 2026 budget. This should give Skyco two new addition wells within the next year and a half.

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 77 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 have been installed and are almost completed. They have a leak detection notification which should help stop leaks much sooner. This will greatly help in vacant vacation homes in the off season but will help in peak season as well.

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

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   Two additional wells are being added for the two additional trains at Skyco. Infrastructure is in place to add more trains at Skyco or NRO if needed.

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:
