Project Name: Filtration. (10 mgd) - Part 1 <br /> <br />Description: Filtration: includes infrastructure/support facilities for 30 mgd of fi~ters; <br /> instatl filter cells sufficient for only 10 mgd. <br /> <br />Justification: An estimated 30 mgd of filters is required by 2010 to meet dry season <br /> mass limits. Facility Plan proposes phasing filters in sooner to facilitate <br /> development of Level 3 and Level 4 reuse. Provides high quality <br /> secondary effluent and potential level 4 reuse water. Also, needed to <br /> assist with meeting wet season mass ~oad requirements during peak flow <br /> events (under all peak flow management alternatives). <br /> <br />Project Driver: Performance reliability to meet the dry weather NPDES total suspended <br /> solids ~imits of less than 10 mg/L, reuse development, and compliance <br /> with peak flow management. <br /> <br />Project Trigger: NPDES permit compliance for TSS: Dry weather maximum month flow in <br /> excess of 49 mgd. <br /> <br /> Also, initially to provide higher quality effluent so that reuse can be <br /> developed. <br /> <br />Type of Project 25% Capacity; 75% Performance <br /> <br />Estimated Project Cost $10,100,000 <br />(2004 Dollars): <br /> <br />Phasing: Budgeted for FY2008/09 <br /> <br /> Project Name: New Bankside Outfa~l <br /> <br /> Description: Bankside out[all to accommodate 117 mgd (277 mgd less 160 mgd which <br /> is the estimated capacity of the existing outfall system after secondary <br /> treatment modifications. <br /> <br /> Justification: New bankside outfall is required to pass the peak wet weather flow to the <br /> river. <br /> <br /> Project Driver: After secondary treatment modifications are made, a maximum peak flow <br /> of 160 mgd can pass through the existing outfa~ box without submerging <br /> the secondary cladfier weirs. <br /> <br /> Project Trigger: Peak wet weather flows in excess of 160 mgd. <br /> Type of Project t 00% Capacity <br /> Estimated Project Cost $1,500,000 <br /> (2004 Do~iars): <br /> Phasing: Budgeted for FY2009/10 <br /> <br /> <br />
