Metropolitan Wastewater Management Commission Capital Improvement Program <br /> <br />TERTIARY FILTRATION - PHASE 1 <br />Description: <br /> The phased work program will install infrastructure/support facilities for 30 mgd of filters <br />for tertiary filtration of secondary treated effluent. The first phase/project only installs <br />filter system technology sufficient for 10 mgd of treatment. Future phases/projects will <br />install the remaining filter technology. Some of the project funding will support the <br />treatment plant landscape upgrades. <br />Justification: <br /> Up to 10 mgd of filtration is required by 2010 to meet dry season mass limits, with the <br />need for filtration increasing to up to 30 mgd by the end of the planning period (2025). <br />The 2004 MWMC Facilities Plan proposes phasing filters on an as-needed basis. <br />Filtration provides high quality secondary effluent and potential level 4 reuse water. <br />Also, filtration is needed to assist with meeting wet season mass load requirements <br />during peak flow events. <br />Status: <br />As of December 17, 2009, the design was at the 90% development level and project <br />team continues to work on establishing a filter equipment price agreement that will be <br />assigned to a construction contractor. <br />Project Driver: <br />Performance reliability to meet the dry weather NPDES total suspended solids limits of <br />less than 10 mg/L, reuse development, and compliance with effluent limits during peak <br />flow conditions. <br />Project Trigger: <br />NPDES permit compliance for TSS: Dry weather maximum month flow in excess of 49 <br />mgd. Also, initially to provide higher quality effluent so that reuse can be developed. <br />Improvement <br /> SDC Eligibility: <br />42% <br />Estimated Project Cost <br />: $14,685,000 (Note: Part of the project money will support the treatment plant <br /> landscape upgrades. Also, MWMC has received a state revolving fund (SRF) loan <br /> for the tertiary filtration project) <br />Expected Cash Flow: <br />FY 07-08 = $236,186; FY 08-09 = $554,241; FY 09-10 = $6,200,000; <br />FY 10-11 = $7,694,573 (construction, landscape, administration, etc.) <br />Prior2009-10 <br />Expenditure/Category:YearsEst.
