Coyner Spring Water Treatment Facility

The City’s primary drinking water source, Coyner Spring, was determined to be groundwater under the influence of surface water. First, we developed a plan for emergency usage of the spring by pre-chlorinating the spring box in order to obtain adequate CT. We assisted with equipment selection and prepared a Request for Proposals for solicitation of microfiltration or ultrafiltration membrane treatment equipment, and participated in the review of those proposals. After selection of equipment, we began design of a 6.0 MGD water treatment facility for the City. The work included upgrades to the source water pumps, a new 11,000 square foot building for water treatment and operations, layout of the membrane treatment pumps, filter skids, and chemical cleaning equipment, chlorination and fluoridation equipment, a 1.0 million gallon clearwell, finished water pumps, and a SCADA base station. Draper Aden Associates was the prime engineer for this project and performed surveying, site planning, process, and structural engineering, and coordinated with building subconsultants for architecture, HVAC, plumbing, and electrical design.
