Document Description
Metropolitan's Jensen Plant has a total of 20 granular tri-media filters. Despite receiving routine maintenance, the existing steel surface wash header pipes and appurtenances at Filters Nos. 1-20 have deteriorated through continual use over their 30 years of operation. Metropolitan proposes to conduct backwash system upgrades, which include replacement of the corroded 15-inch diameter surface wash header pipes and conversion of Jensen Filters Nos. 1-20 to fixed nozzle surface wash systems. This project will make Filters Nos. 1-20 consistent with all other filters at Metropolitan's treatment plants.
