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 48 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.    We have reached out to engineering firms for proposals on looking at ways to maintain water quality. This will help with the demand and need to flush lines. We are looking at a program to upgrade our meter system to all AMI meters. This would allow us the ability to monitor on a more frequent basis.

Are there other demand management practices you will implement to reduce your future supply needs?   Look at upgrading our meters to better identify any spots that many need more attention.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   The county has bought property close to the lake for a future surface treatment plant.

How does the water system intend to implement the demand management and supply planning components above?   Utilize engineering firms to help create a plan along with any permitting needs. We would use other government agencies and engineering firms to identify grants and other means for funding. The county does have an account for savings to help fund a future treatment plant.

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:
