The City updated its Water Distribution system master plan in 2024. A part of the plan update included population projections to planning year 2050. Population estimates for the water service area were based on projections developed by the French Broad River Metropolitan Planning Organization for traffic analysis zones (TAZs) as well as city staff knowledge for predicted growth. For purposes of this local water supply plan, the City extrapolated to planning year 2070.

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 36 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.    Hendersonville has a city sponsored rain barrel program to reduce drinking water usage for irrigation and other non-potable purposes. Hendersonville plans to continue this program.

The city promotes water conservation through a robust outreach and education program.

Additionally the City offers several rebates for efficient toilets, washing machines, dishwashers, customer side shut off valves, and smart irrigation controllers.

The City has an AMI system and utilizes Aquahawk services for its customers to find and identify private side leaks as well as set consumption goals.

Are there other demand management practices you will implement to reduce your future supply needs?   The City utilizes a residential increasing block rate structure for residential customers and plans to continue this practice.

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?  The City updated it's water system distributions system master plan and water treatment master plan in 2024. Generally the plans project future demands and identifies capital improvements to eliminate low pressures, remedy deficient fire flows, and supply future water demands.

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:
