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 altematives). <br /> <br />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 /> <br />NPDE8 permit compliance for T88: 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 />25% Capacity; 75% Performance <br /> <br />$10,100,000 <br /> <br />$14,685,000 <br /> <br />Programmed for FY 2008f09 <br /> <br />Page 76 <br /> <br />FY 06-07 BUDGET AND CIP <br />
