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 48 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.    System will conduct regular water audits.

Are there other demand management practices you will implement to reduce your future supply needs?   System will conduct regular water audits.

What supplies other than the ones listed in future supplies are being considered to meet your future supply needs?   System will explore increase in purchase contract if necessary.

How does the water system intend to implement the demand management and supply planning components above?   System will utilize expertise of utility partners in City of Hickory.

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:   Catawba County has been working with Freese & Nichols on a water system needs analysis for this exact purpose. The county intends to add additional storage to be triggered by future development and will be adding this component to the Capital Plan. They are also planning to increase their purchase contract with Hickory to increase their purchase allocation.
