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 55 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? The City is partnering with an engineering consultant to perform a comprehensive Source Water Supply Study to evaluate the capacity, reliabiity, resilience, regulatory feasibility, and long-term sustainability of the City's existing water supply assets and to identify and assess potential supplemental or alternative water sources capable of meeting current and projected demands.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs? See previous note.

How does the water system intend to implement the demand management and supply planning components above? See previous note.

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: The City is partnering with an engineering consultant to perform a comprehensive Source Water Supply Study to evaluate the capacity, reliabiity, resilience, regulatory feasibility, and long-term sustainability of the City's existing water supply assets and to identify and assess potential supplemental or alternative water sources capable of meeting current and projected demands.
