GUM' <br />County ARo►nWy <br />Phone (414) 542 -02 <br />In response to your request I am providing additional information <br />concerning our request for a supplemental water supply from <br />aVASA • <br />Effective this summer, Chatham County will have a total daily <br />supply availability of 8650000 gallons, 500,000 aeen <br />vf( wells in <br />the water plant and the remaining 365,000 gpd from <br />the North Chatham area. Our current average day demand is <br />294,975 gallons, while the peak day event is 480,410 gallons. <br />In addition to the supply and demand conditions, Chatham County <br />expects to have a 1.1 million gallon storage tank operational by <br />the fall of 1992. The overflow elevation on this tank will be <br />+ -740.0 once completely filled. The size of this tank provides <br />over three days storage, based upon normal demand. The North <br />Chatham, system has a factor of safety of 1.8 between the peak day <br />event and supply availability. However, based upon an additional <br />900+ vacant lots in the North Chatham system already permitted <br />for public water supply, the State water Supply section has taken <br />a more restrictive posture. Based upon their interpretation Of <br />the 400 gpd /350 gpd per dwelling and vacant lot rule, Chatham <br />County currently needs over 900,000 gpd supply availability. <br />If a mid-term supply agreement can be achieved, it is Chatham <br />County's desire to.have a water plant near Lake Jordan <br />
