Page 6 <br /> includes high-density areas widely separated by open space or low density development.A number of <br /> decentralized, small-scale denitrifying treatment technologies are available to accommodate flows from small <br /> communities, neighborhoods, business districts,so on so forth. Compared to individual on-site denitrifying <br /> systems,the cost of STEP systems with cluster treatment plants can be significantly lower, along with space <br /> needs and on-site maintenance requirements and costs. <br /> This approach allows development of denitrifying systems in critical areas in small increments, <br /> involving smaller amounts of up-front capital costs. No other collection system or treatment system <br /> technology allows such an incremental approach without unbalanced costs to initial users. More detailed <br /> discussion, specific to each service area follows: <br /> Back Road Site Collection Area <br /> The Back Road service area is an established neighborhood of approximately 438 existing homes. There is no <br /> apparent commercial property. The service area is located adjacent to two small lakes with a topography that <br /> varies about 40'and with a general slope towards the lakes. Lots appear to be in the range of 1/4 acre and <br /> vegetation appears to be very established. An aerial of the area is show below: <br /> I Gent. <br /> 436311 0,2011 iutops PTechnologie% 2009GOOSIC <br /> ,. <br /> Treatment capacity does not exist at this time but could be provided in the northeast region of the service area. <br /> All wastewater would be conveyed uphill to reach the proposed treatment area. The longest pumping distance <br /> would be approximately one mile. <br /> We would anticpate that this area could easily be serviced with a STEP collection system. We would not require <br /> list stations as all STEP system would eaily pump directly to the point of treatment. Additionally, the STEP units <br /> could also pump to treatment located in the Heritage Park of Southport service area if it was advantageous to do <br /> SO. <br /> Heritage Park Site Collection Area <br /> The Heritage Park service area is an established area that includes a mix of residential, commercial, industrial <br /> and recreational property. It is located adjacent to a small lake with a topography that varies about 60' and with a <br /> general slope towards the lakes.An aerial of the area is show below: <br />
