SAWS Dos Rios Chlorine System Improvements
In January 2019, MGC was awarded the contract to renovate the existing sanitation and dechlorination systems at the Dos Rios WRC. This includes brand new instrumentation and controls, feed equipment, and piping. SAWS operators now have 2 new RIO cabinets (1 Chlorine & 1 SO2), a new, expanded 7-57 Controller from Emerson, as well as 9 new Evaporators, 10 Chlorinators, and 3 Sulfonators, and various ancillary components, including 18 new Cylinder Scales, 2 new Overhead Coiling Doors, 13 new Unit Heaters, and a cutting-edge CL2/SO2 Leak Alarm System. Also, MGC installed 30,000 feet of new PVC and steel piping, dozens of pressure instruments, analytical devices, diffusers, and chemical injectors, just to name a few.
C.C. Cragin Reservoir Water Supply
2020 AZ Water – Treatment Plant of the Year!
MGC delivered a 5.5 MGD water treatment plant to the Town of Payson. The plant is fed from the natural spring water at the CC Cragin Reservoir. Due to the elevation and topography, a hydroelectric generator was installed to eliminate high head pressure while providing electricity for plant use. The project included a concrete flocculation tank, an engineered metal building, a microfiltration system (4 filters – 86 modules), a CIP/backwash system, chlorine generation, water pumps, a process air system, distribution pumps, and a fully automated PLC/MCC line up. The project also included construction of a .5 MG post tension concrete water reservoir. Steel and iron were 100% domestically sourced and fabricated, adding focus on procurement.
