Coming together over twenty years ago, SSJID and the cities allied themselves in an attempt to balance the agricultural and urban needs concurrently. The planning, environmental, and engineering phases of the project took place between 1997 and early 2003. Gaining public support and involvement was a key aspect, with efforts beginning in 1998 and continuing throughout the final pipeline and facility construction. The Water Treatment Plant and pipeline construction phases extended from July 23, 2003 to mid-2005. The first water deliveries took place in June 2005. In July 2005, the South County Water Supply Program celebrated its momentous achievement in dedicating the plant to the late SSJID Board Director Nick C. DeGroot. Currently delivering to Manteca, Tracy, and Lathrop, the Water Treatment Plant is expected to connect to Escalon during Phase II of the project, set to take place in a few years.
The state-of-the-art Nick C. DeGroot Water Treatment Plant operates under the Zenon 1000 Submerged Membrane System. The multi-barrier treatment approach removes most of the particles and further protects public health during a disinfection process. The water comes from SSJID’s Woodward Reservoir and is clarified through a dissolved air floatation process. It then moves into the membrane filtration system. The California Department of Health Services granted this process the highest rating for removal of giardia and cryptosporidium.
The Water Treatment Plant can process approximately 40 million gallons per day (MGD). In addition to the 37 miles of transmission pipe, which are capable of holding 14 MGD, there are four pump stations and three large storage tanks along the pipeline. The pump stations deliver water from the pipeline to the city water lines, while the storage tanks are capable of holding one million gallons of water. During Phase II of the project, one pump station and two additional tanks will be added.
The South County Water Supply Program provides water to over 155,000 residents. The Nick C. DeGroot Water Treatment Plant is fully staffed with highly qualified individuals. Together, they are committed to successfully meeting the area’s domestic water needs.
