How much water was used for system processes (backwash, line cleaning, flushing, etc.)?   0.0120 MGD

We are unmetered so we estimate the use based on 100 gpd residential connection and 150 gpd commercial connection. (commercial connection is seasonal)

The high amount of unaccounted water is resulting from our aging distribution system. The water system was built when Fontana Dam was constructed in the 1940's. The only customer we have besides the 25 residential customers is Fontana Village Resort. It wasn't until 2011 that the town was formed. The resort owned the system until then. It is such a small system there aren't any funds available to redo the distribution system which is what is needed. We received a grant in late 2023 and are still in the process of approving an engineering firm. We are hopeful we can make some significant improvements with the monies received.

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 100 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?  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:
