for Little Falls Water Treatment Plant by Satish Shah, Bureau of Engineering North
The Passaic Valley Water Commission (PVWC) received SFY 2002 funding for the largest amount ever awarded under the New Jersey Environmental Infrastructure Financing Program-$65.8 million. The proposed project will upgrade PVWC's Little Falls water plant to meet the existing and future demands of its customers and the future Safe Drinking Water Standards treatment requirements. The PVWC's transmission and distribution system consists of 14 pumping stations, 3 finished water reservoirs, 6 water storage tanks, and over 500 miles of conveyance piping ranging from 4 to 60-inches in diameter. The commission owns and operates the drinking water distribution systems of Paterson, Passaic, Clifton, Prospect Park, and Lodi. The PVWC Little Falls plant provides potable drinking water directly and indirectly to approximately 750,000 residents in 41 municipalities. Although the PVWC is in compliance with current drinking water regulations, the plant's existing treatment processes will not be adequate to comply with the Stage I Disinfectants and Disinfection Byproducts and the Interim Enhanced Surface Water Treatment rules. The PVWC will be subject to these federal limitations on January 1, 2004. The proposed project will include the replacement of existing raw water pumps, removal and replacement of the existing flocculation/sedimentation process with a new ballasted flocculation process, construction of new ozone treatment system, upgrading and retrofitting of the existing gravity filters to convert to biologically active GAC filters, installation of filter-to-waste piping for the filtration system, rehabilitation and replacement of existing chemical storage and feed systems, construction of backwash equalization facilities, upgrading the existing filter backwash system, construction of new plate settler/thickener units, and upgrades to the existing laboratory, instrumentation, controls and electrical systems.
