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 61 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?   A more detailed plan will be implemented if our IBT submittal is approved.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   None

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, CATAWBA-WATEREE Drought Management Advisory Group
CWWMG Water Loss Program
CWWMG Integrated Water Resources Plan Inter-basin Transfer Data

What major water supply reports or studies were used for planning?  Water and Wastewater Comprehensive Master Plan, completed in 2021.

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:
