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 unavailable until we receive population data for 2024 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?   

Additional Information

Has this system participated in regional water supply or water use planning?  Yes, WSACC contracted Black & Veatch for an updated Master Plan that was finalized in July 2024. The final document included an evaluation of existing water supplies and adequacy of those supplies relative to projected future demands. WSACC member jurisdictions have provided projected demand data and other data requests by Black & Veatch for this effort, and member jurisdictions received documentation from the Master Plan as part of their water supply planning efforts moving forward.

What major water supply reports or studies were used for planning?  Master Plan

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:   WSACC member jurisdictions manage any concerns related to overall number and adequacy of water supply sources withdrawal, treatment, and distribution. See associated responses from WSACC member jurisdictions.
