J-124 Digester Gas Facilities Rehabilitation Mar-2017 Victoria Pilko The project will modify,rehabilitate,and repair digester gas handling facilities at both Plant 1 and Plant $53.400.000 2.Facilities affected include low pressure gas vents on all oigesters,new gas compressors and Start of Consultant pryers and a low pressure gas flare system to replace the existing high pressure system with a low pressure system.Sections of the gas Dieing need modification to manage condensation and corrosion. The work may include replacement of the existing gas compressor buildings at both plants,but at Plant 1,a temporary gas compressor facility may be needed to allow reuse of the existing gas compressor building. outreacheffort 5-67 Bay Bridge Pump Station and Forcemain May-2017 Adam Naxarolf This project will replace and potentially relocate the existing Bay Bridge Pump Station.The Bay Bridge $26,500,000 Replacement force mains from the pump station to the west side of Upper Newport Bay will also be replaced and the size increased. 7-65 Gisler-Red Hill Interceptor Jan-2018 Wendy Smith This project will rehabilitate the Gisler Redhill Interceptor from a diversion manhole near the Main $9,600,000 Rehabilitation Street Pump Station to the College Avenue Pump Staton.The protect is expected to line or repair 38 manholes antl roximate 15 000 feet of VCP sewer in Costa Mesa. 1-101 Rain and Bristol Street Sewer Extension Jan-2018 Wendy Smith This project will replace 2,360 linear feet of 21-inch City of Santa Ana sewer with a 24inch Sanitation $7,800,000 Districts sewer line and a parallel 8-inch City of Santa Ana sewer line to allow for redirecting all house lateral connections-The sewer line is located along Myrtle Street.between Rain and Bristol Streets in the City of Santa Ana-The project also includes rehabilitating 910 feet of 18-nch VCP,7,075 feel of 21- inch VCP,and 2,570 feet of 24-inch VCP pipe and associated manholes in Bristol Street and Ram Street. • Jan 2020 P2-128 Digester Process Upgrades at Plant 2 Aug-2017 Jeff Mohr This project is the largest of a set of related projects to replace the mesophilic anaerobic digesters at $260,000,000 Plant 2 with new digesters in a temperature-phased anaerobic digester(TPAD)configuration-This project will include six new themophilic digesters,batch tanks,coding facilities,and associated sludge pumping,digester mixing,power distribution,and controls.Replacement and demolition of existing i i esters will be includetl in a se rate ect.
