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 43 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.    No Changes

Are there other demand management practices you will implement to reduce your future supply needs?   Improved and systematic flushing for targeting specific areas and reducing non-revenue water usage. Enhanced CIP to replace older water lines to effectively reduce water loss.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   Developing a new water intake from Neuse River and additional utility partnerships.

How does the water system intend to implement the demand management and supply planning components above?   Continued work with consultants to evaluate supply options and implement new water distribution model for more effective management of the system and flushing operations.

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, Yes, the Town of Clayton is a member of Triangle Water Supply Partnership and has been a part of regionalization studies.

What major water supply reports or studies were used for planning?  NC Hwy 401 Corridor Study and Updated regional forecasts through Triangle Water Supply Partnership

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:   Additional storage will be required and is planned to meet half average day demand requirements.
