Assumes additional <br />basement floor space is not required. <br />JUSTIFICATION: Provides additional ~paci~ for WAS thickening and potentially delays ~e ~nstmction of <br />additional digestem. <br />PROJECT DRNER: AddEional ~paci~ to provide WAS thickening with one unit offiine at ~MW upper limit <br />flow pmje~ions. Nitration required by the NPDES pete and increasing wastewater <br />flows and loads generates mom WAS solids. Provide abili~ to ~nduct recupe~tive <br />thickening so that need for additional digestion volume ~n potentially be defe~ed. <br /> <br />PROJECT TRIGGER: Exceeding solids and hydraulic loading rate design criteria. <br />TYPE OF PROJECT: 100% Capacity <br /> <br />ESTIMATED PROJECT COST $2,500,000 <br />(2004 Dollars): <br /> <br />INFLATED PROJECT COST $2,570,000 <br />(2005 Dollars): <br /> <br /> PHASING: Budgeted for FY 2005/06 <br /> <br /> Page 65 <br /> <br /> <br />
