We would not require <br /> lift stations as all STEP system would eaily pump directly to the point of treatment. <br /> Funding/Concept Plan/Critical Areas <br /> The Sewer Commission and Planning Department have developed a concept plan demonstrating a potential <br /> approach to providing denitrifying wastewater treatment in critical areas of Mashpee. Ongoing studies of <br /> nitrogen impacts and loads may result in wastewater treatment facilities throughout Mashpee. However, <br /> priorities are established for funding, based primarily on studies and consultant work. The Town of Mashpee's <br /> intent is to address critical areas in small increments, involving smaller amounts of up-front capital costs. <br /> Technology Description <br /> Orenco Effluent Sewer <br /> The collection system is an Orenco Effluent Sewer, a technology that has been optimized for more than 25 <br /> years. With an Orenco Effluent Sewer, raw sewage flows from the building to a watertight underground tank, <br /> where primary treatment occurs via settling and natural biological processes. Solids remain in the tank, <br /> decreasing in volume,which reduces biosolids treatment costs at secondary treatment facilities. Filtered liquid <br /> effluent is then discharged (by high-head pump or gravity)through small-diameter service laterals to small- <br /> diameter collection lines. These service and collection lines are shallowly buried and follow the contour of the <br />
