Vanir provided project and construction management services for the City of Lemoore’s Water Treatment Plants. Located in the Central Valley, the City of Lemoore has one of the most challenging water quality compositions in California — it contains elevated levels of arsenic, iron, ammonia, total organic carbon and color and has excessive levels of trihalomethanes when chlorinated. In order to meet state and federal standards, wellhead treatment plants were built at two of the City’s reservoir locations.
Vanir supported the design-build entity and the City in meeting all contract requirements while maintaining an aggressive project schedule. The team brought expertise in water treatment technology to facilitate design and operational considerations during the development of the GMP.
The City selected an innovative technology strategy for the water treatment process, involving the use of pre-ozonation followed by granular activated carbon, to create biological filtration units which are then followed by anion exchange units. The project resulted in many benefits to the City; not only are the treatment plants capable of delivering 10,500 gallons per minute of water-bottle quality drinking water straight out of the tap, but there are less operational expenses related to ongoing chemical costs, reduced issues at the source and minimized waste stream.
