Segment 3-A1 Update

The Surface Water Supply Project is currently advertising the Segment 3-A1 Construction Project. Work of Contract is construction of approximately 14,000 linear feet of 42-inch diameter waterline with all necessary valves and appurtenances, along a CenterPoint Energy powerline corridor from south of Clay Road to the connection to Segment C located north of Tanner Road. The proposed water line installation will consist of primarily open cut construction; however, trenchless methods are required at crossings of HCFCD facilities, City of Houston (COH) roads, CenterPoint Energy Overhead Power Towers, and crossing of private/public utilities. Additionally, the Work requires installation of air valves, butterfly valves, pre-cast concrete manholes, and cathodic protection facilities, and removal and replacement of existing fencing and pavement surfaces (concrete, asphalt, and gravel).

Sealed Bids, addressed to West Harris County Regional Water Authority, will only be received electronically using the “E-Bidding” function on the CivcastUSA website ( until 2:00 PM, Local Time, March 18, 2021 for “Construction of Segment 3, Contract S3-A1 for the West Harris County Regional Water Authority (WHCRWA), Harris County, Texas.” More information is available at

Design for the proposed Surface Water Supply Project, including over 55 miles of water line and two large pump stations began in Spring 2016. As of December 2020, design for the entire Surface Water Supply Project is nearing completion, with design of some segments progressing more quickly than other segments along the alignment.

Construction of the project is anticipated to take place from 2020 to 2025 and will be completed in segments. In other words, the waterline will be built one piece at a time. Construction schedules are NOT set, and your area will only be impacted for part of the construction phase. Your safety, ease of access, and well-marked detour information will be our priority throughout the life of the project.

Construction of Segment 3A-4 began in late 2019, and additional construction along Segment C will begin in early 2021. The project is anticipated to be complete in 2025, with delivery of surface water to WHCRWA and NFBWA residents through this water line at that time.
