When rain events occur, the turbidity, organics and alkalinity of the water in Lake Houston can change drastically, making it challenging for the city of Houston to treat.
To address these challenges, the City of Houston, in association with four regional water authorities decided to expand its Northeast Water Purification Plant (NEWPP) from 80 million gallons per day (mgd) to 400 million, dramatically increasing its ability to support steady residential and commercial growth, while reducing dependency on groundwater.
As part of the expansion, the Houston Waterworks Team – a joint venture between CDM Smith and Jacobs Engineering – is designing and constructing a new raw water facility, including intake, pumping and conveyance to withdraw raw water from Lake Houston and deliver it about 1.5 miles away to the expanded NEWPP.
Features of the project include the design, construction and commissioning of an intake pump station; twin 108-inch transmission mains; pre- and post-treatment chemical addition; flocculation and sedimentation basins; ozone treatment; filtration; finished water storage tanks; and a high-service pumping station.
Balfour Beatty was selected to perform part of the NEWPP Early Work Package 6.
