Because a variety of <br />customer types are grouped into the commercial category, it is difficult to differentiate <br />water usage between the customer types. <br /> <br />These customer types could be divided into individual billing groups, enabling their <br />water usage to be more easily tracked. Table 7-2 proposes a new customer billing <br />method where customer types are individually identified. This would improve Erie's <br />ability to monitor water usage among customer types. These data could be useful in <br />developing future conservation measures/programs customized to specific <br />customer/billing groups. <br /> <br />Table 7-2 Billing Categories <br /> <br />Billing Period I Billing Types I Customer Types <br />Historical/Current Billing Residential Residential indoor and outdoor use <br />System Commercial Commercial indoor & outdoor use <br /> LiQht industrial indoor & outdoor use <br /> Parks irrigation <br /> HOA irrigation <br />New Billing System Residential Residential indoor and outdoor use <br /> Parks Parks irriQation <br /> Commercial Commercial indoor & outdoor use <br /> Light industrial indoor & outdoor use <br /> HOA irrigation HOA irrigation <br /> <br />7.2.5 DistributionfTreatment System Efficiency <br /> <br />Leak Repair <br /> <br />As discussed in Section 2.6, Erie is responsible for the maintenance and repairs of all <br />pipelines within its distribution system not on private property. Residents may report <br />water leaks by calling a hotline. This program has proven effective in addressing water <br />leaks within a reasonable period of time, reducing the amount of water that is wasted. <br /> <br />Leak Detection Program <br /> <br />As discussed in Section 2.6, Erie has historically implemented a leak detection <br />program in older/historic areas of town. This service was expanded to the more <br />modern Northridge and Melody subdivisions in 2006. This program has been useful <br />in detecting leaks and the repair of these leaks has reduced system losses. Erie plans <br />to continue to implement this program, focusing on certain areas of the distribution <br />system each year. <br /> <br />Use of Treated Reclaimed Water for Flushing/Cleaning of SWRF's System <br /> <br />The SWRF has historically used potable water for the flushing and cleaning of the <br />plant. In the future, Erie plans to use treated reclaimed water instead of potable water. <br />This will reduce the plant's potable water usage by approximately 17 AFY <br />(15,000 gallons per day [gpd]) and ultimately Erie's annual usage of first-use water. <br /> <br />DRAFT <br /> <br />7-6 <br /> <br />\\DENSVR1\PROJECTS\9228 - ERIE\CONSERVATION PLAN\REPORT\DRAFT PRIOR TO PUBLIC REVIEW\CONNIE FORMATTED\SECTION 7.DOC <br />
