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. |

Central Weber Sewer Improvement District WWTP System Integration | 2004-2019
SKM has been the Systems Integrator for Central Weber for the past 10 years. Over those years we have upgraded their antiquated PLC’s, upgraded HMI software performed a 60MGD plant expansion and we upgraded their solids handling/dewatering controls. SKM successfully tied the SCADA system to their CMMS software. The SCADA system was setup with a redundant ring style network and we are utilizing Ignition for launching HMI clients over secure WiFi connections to tablets. Central Weber Sewer Improvement District WWTP Expansion | 2007-2012 In 2007 SKM joined with MWH and performed instrumentation and controls engineering for a new activated sludge plant that was constructed adjacent to the existing plant. SKM provided construction management services for the project and is also acting as systems integrator. SKM will provide 19 PLC panels and network cabinets. As the systems integrator, SKM programmed the PLCs and the HMIs throughout the plant and seamlessly integrated the new plant with the existing plant. Along with the process control SKM was also contracted to do the HVAC controls for the new plant expansion. The project included 14 air handling units in eight buildings. Allen-Bradley ControlLogix were used in each building. Several buildings utilized AB Flex remote IO drops for air handling units. Operators were able to use Allen-Bradley OITs at each building to completely control the HVAC system. The HVAC system was also put on their overall SCADA system using the GE iFix platform. |
