Facility <br /> Plan proposes phasing filters in sooner to facilitate development of Level 3 and Level 4 <br /> reuse. Provides high quality secondary effluent and potential level 4 reuse water. Also, <br /> needed to assist with meeting wet season mass load requirements during peak flow events <br /> (under all peak flow management alternatives). <br /> PROJECT DRIVER: Performance reliability. to meet the dry weather NPDES total suspended solids limits of less <br /> than 10 mg/L, reuse development, and compliance with peak flow management. <br /> PROJECT TRIGGER: NPDES permit compliance for TSS: Dry weather maximum month flow in excess of 49 mgd. <br /> Also, initially to provide higher quality effluent so that reuse can be developed. <br /> <br /> Ii <br /> TYPE OF PROJECT: 25% Capacity; 75% Performance <br /> ESTIMATED PROJECT COST $10,100,000 <br /> (FY 2004-05 Dollars): <br /> INFLATED PROJECT COST $12,076,000 <br /> (Inflated Dollars -Multi-year): <br /> PHASING: Budgeted for FY 2008/09 <br /> i <br /> Page 74 FY OS-06 BUDGET AND C:[P <br /> <br />
