As stated by Dare Co Regional, in the event that the system is producing ninety percent of its capacity on two consecutive days in the previous twelve months or if a purchase system exceeds their allocated amount of water on two consecutive days in the previous twelve month period, Dare Co Regional shall immediately begin work to expand the production system, in not less than one million gallon per day increments.

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 95 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?   

Demand projections (2010-2030) based on peak usage for summer months of June, July, and August (8.409 mgd) and the seasonal population provided. As stated by Dare Co Regional, in the event that the system is producing ninety percent of its capacity on two consecutive days in the previous twelve months or if a purchase system exceeds their allocated amount of water on two consecutive days in the previous twelve month period, Dare Co Regional shall immediately begin work to expand the production system, in not less than one million gallon per day increments.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes

What major water supply reports or studies were used for planning?  Additional historical materials were included with the submission of the LWSP and is available in the files.

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:   NRO has applied for a permit from the State to expand production capacity from 3MGD to 5 MGD.
Skyco completed it's anion exchange improvements in 2002 and has a 3MG reserve in the Capital Improvement Plan for 2004-05.
