Project Description

The North Gilbert Water Treatment Plant (NWTP) was constructed in the late 90’s for an initial capacity of 15 MGD and expanded in 2002 to a maximum month flow of 45 MGD. NWTP receives its source water from SRP via the Eastern Canal. SRP manages several dams and reservoirs on the Salt and Verde rivers and several dams east of Phoenix. The water is conveyed to Gilbert through a series of canals, including the Eastern Canal. The facility is operational year-round except when the SRP conducts periodic canal dries up to perform construction and maintenance in and around the canals. The NWTP site also includes one groundwater well, that is used to blend the NWTP surface water just prior to the finished water reservoirs to manage arsenic and nitrate concentrations. Groundwater can also be blended at the front of the plant.
The project is to design a new Water Treatment Plant (WTP) in Gilbert, Arizona. The new facility will need to initially treat 45 million of gallons per day (MGD) in of water in 2021 and be able to treat 70MGD by 2050.
