Valley City water is sourced from wells in the Valley City aquifer and the Sheyenne River.
The Valley City Water Treatment Plant was originally built in 1972 as a Grade 4 Lime softening plant. This process was called conventional treatment, which included chemical with a simple sand filter and chlorine disinfection as the last stages of the process. It was built mainly to soften and disinfect water from the Valley City Aquifer and the Sheyenne River.
Recently the Valley City Water Treatment Plans was retrofitted with an addition built on to the existing plant. It consists of a combination of ultrafiltration (low pressure) and nanofiltration (high pressure , or loose R.O.) to treat the existing ground and surface waters. This was mainly constructed to accommodate the sulfate issues of the up stream flows of Devils Lake. This new process treats the water mainly through filtration, in comparison to the previous chemical treatment of lime.
Water quality reports are issued annually.
