City of Houston 108-Inch Diameter Waterline – Houston, TX

Client: City of Houston


Segment Number: 99E-1


Construction Cost: $32.5 Million


Services: Preparation of Plans, Specifications, Contract Documents, Final Design, Construction Phase Services


Location: Houston, Texas


Anticipated Completion Date: Spring 2019 (Design), 2021 (Construction)

In 2016, Jones|Carter was selected by the City of Houston to design approximately 6,000 linear feet of 108-inch diameter water transmission line adjacent to the Harris County Flood Control channels located immediately south of Beltway 8 from Willis Street to Imperial Valley Drive.
Spurred by population growth, regional water demands, and the conversion from ground water to surface water, the City of Houston implemented expansions for the Northeast Transmission Water Line (NETL) and the Northeast Water Purification Plant (NEWPP) as part of the City’s Surface Water Transmission Program (SWTP).
The NETL is a 16.5-mile, multi-year expansion that will convey surface water from the NEWPP to the North Harris County Regional Water Authority’s (NHCRWA) meter station. The expansion of both the NEWPP and the NETL are essential to meet the projected 2040 water demand for the region as well as to aid in the conversion to surface water.
The J|C team is currently designing the 1+ mile segment accompanied with construction drawings, technical specifications, and contract documents for the NETL Project. J|C is striving towards the 90% milestone to complete design by the Spring of 2019. The design team was tasked with an accelerated schedule to help ensure corresponding projects are not impacted.
Construction of the transmission line will be performed by a combination of open cut and tunneling construction methods. Critical to the project’s success was the coordination of six major tunnel crossings, including Hardy Toll Road, the Union Pacific Railroad, and several Harris County Flood Control District Channels. For these, the design team coordinated with Harris County Flood Control, Harris County Toll Road Authority, and the Union Pacific Railroad to meet the milestone deadlines.
The project also includes roadway repair and replacement as needed for construction. The project will be constructed entirely in dedicated easements with exception to roadway and drainage channel crossings.
