Assumes additional <br />basement floor space is not required. <br />JUSTIFICATION: Provides additional capacity for WAS thickening and potentially delays the construction of <br />additional digesters. <br />PROJECT DRIVER: Additional capacity to provide WAS thickening with one unit offline at WWMW upper limit <br />flow projections. Nitrification required by the NPDES permit and increasing wastewater <br />flows and loads generates more WAS solids. Provide ability to conduct recuperative <br />thickening so that need for additional digestion volume can potentially be deferred. <br />PROJECT TRIGGER: Exceeding solids and hydraulic loading rate design criteria. <br />TYPE OF PROJECT: 100% Capacity <br />ESTIMATED PROJECT COST $2,500,000 <br />(2004 Dollars): <br />INFLATED PROJECT COST $2,570,000 <br />(2005 Dollars): <br />PHASING: Budgeted for FY 2005/06 <br />Page 60 FY 04-OS BUDGET AND CIP <br />
