Body
BACKGROUND
The City of Dallas owns and operates two wastewater treatment plants with a combined treatment capacity of 280 million gallons per day. Central Wastewater Treatment Plant ("CWWTP") is the larger of the two plants, located just south of downtown Dallas. The non-potable water system at CWWTP utilizes treated wastewater for various plant water demands, thereby conserving potable water. Non-potable water is used for filter backwashing, equipment cooling, and mechanical seal water. The current non-potable system consists of a main pump station, storage tank, booster pump station, pipelines, and appurtenances. These facilities have been constructed over the years as CWWTP has grown and treatment needs have changed.
On January 12, 2022, the City Council authorized a professional engineering services contract with Lockwood, Andrews & Newnamman, Inc., to provide engineering services required for investigation, preliminary design, development of construction plans and specifications, bid phase services, construction administration and start-up associated with the non-potable water system improvements at the Central Wastewater Treatment Plant.
