Big Cottonwood Water Treatment Facility
WTP Electrical & SCADA Upgrade
|
|
Located at the mouth of the Big Cottonwood Canyon, the Big Cottonwood WTP is one of three water treatment facilities providing treated water to Salt Lake City (SLC), Utah. The utility distributes water through about 1,300 miles of transmission and distribution pipe to over 90,500 connections. SKM has been providing on call services for the Big Cottonwood Water Treatment Plant since 2005.
The original treatment plant was constructed in 1957. In the 1980’s, the plant was renovated to treat 42 MGD (roughly 40 percent of the water treatment capacity for SLC) and a gas chlorine system was installed for disinfection. Due to increased concerns and risks associated with communication of the PLC system as stated by or client, “the old one was not reliable and required diligence”. In 2015 SKM was selected to perform a SCADA master plan for the facility and to design and integrate a complete SCADA upgrade. SKM recommended to include in the project a new electrical building adjacent to the filter building to remove as much electrical gear out of the filter building as possible. The facility was taken offline for only two weeks while all of the electrical and controls was transferred to the new building and the plant was brought back online seamlessly. |
