What is this system's off-stream raw water supply storage capacity?   0 Million gallons
Are surface water sources monitored?   ,
Are you required to maintain minimum flows downstream of its intake or dam?   Yes
Does this system anticipate transferring surface water between river basins?   Yes

Based on minimum releases and historical flows, the combined availability from Breadley Creek and the North Fork Mills River has been estimated by McGill Associates to be 5.5 mgd. A downstream minimum release of 8 cfs (5.2 mgd) is required from the Bradley Creek reservoir. A downstream minimum release of 8 cfs (5.2 mgd) is required from the North Fork Mills River reservoir. Mills River withdrawals of 12.0 mgd are always permitted, but when downstream discharges are 30 cfs (19.4 mgd) or higher, withdrawals up to 24 mgd are allowed. See the McGill Associates to DWR leter dated August 21, 1995 for more details.

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 91 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?  Water distribution system study, Hendersonvill NC August 1998, by Finkbeiner, Pettis & Strout, Inc.

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:   The West Ewart resevoir will be put into service in 2003. Renovation of the current WTP is scheduled to begin in 2004 and will be competed in 2006. The design capacity of the renovated WTP is 18 mgd.
