The Catawba System is direct read and billed monthly system, therefore there are no max day readings. There is not a master meter to measure total flow for this system, so readings are taken from individual meter readings of customers.

Regarding the difference between avg. monthly flow (0.0668 MGD) and that entered for permit NC0025542 (0.3937 MGD) - only a portion of the plant flows are from this distribution system. Total plant flows are made up of multiple distribution systems. The average daily discharge for permit NC0025542 (0.3937 MGD) is calculated from all collection systems contributing to that facility. There are not flow totalizer meters on the constituent systems. Currently in design phase to expand Hickory Catawba WWTP (NC0025542) to 3.0 MGD.

Wastewater discharge may not match due to contributing systems not having master meters. Contributory flows taken from individual water meter reading therefore potential or actual I&I is unaccounted for.

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 41 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?   

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:
