Mobile System Removes Nitrates from Well Water
USFilter is providing emergency drinking water services for the removal of nitrate from a dormant well in the Rancho Cucamonga area in Southern California.
The Cucamonga Valley Water District (CVWD) retained USFilter to remove nitrate from a well site that needed to be brought back on line during a recent emergency water shortage in their district. The water district learned in late May that within a week their normal supply of water was to be interrupted due to emergency supply line work by the Metropolitan Water District of Southern California. This shutdown would have reduced the water supply to 43,000 connections by 60 percent. Working with USFilter, the District was able to bring a well sitepreviously shutdown due to high nitrate levelsback on line. The treatment system provided an additional 10 million gallons of water during the emergency water shortage.
Although CVWD received short notice of this outage, USFilter was able to respond with mobile units from its Los Angeles facility and provide an installation at the well site in Rancho Cucamonga. The water treatment system consisted of three on-site units each processing 400 gallons per minute (gpm) of water to remove nitrate.
The units contain an NSF-certified resin that removes the nitrate from the influent water entering the trailers. When the trailers near exhaustion, a fresh trailer was placed on line and the exhausted units were taken to the USFilter plant in Los Angeles for regeneration. This allowed for an uninterrupted supply of treated water for the District with no waste discharge issues at the site.
"The assistance USFilter provided was critical to ensure that we were able to meet the water supply needs of our customers for public health and safety. Their ability to quickly mobilize and implement the treatment system demonstrates their expertise in these types of situations and their commitment to customer service," stated Robert DeLoach, general manager/CEO of the Cucamonga Valley Water District.
Pete Sesing, vice president and general manager for USFilter said, "We were extremely pleased to be of assistance to the District and customers in the service area. This type of work is what we train and prepare to do since no one can predict when an emergency water crisis will hit. We have to be ready all the time."
