84″ Water Transmission Line (Project 25D), IH-45 to the West of Sharmon Rd
Client: North Harris County Regional Water Authority (NHCRWA) Location: Houston, TX
A+ Services designed approx 9,300 LF of 84” water transmission line along easements and CenterPoint Corridor, from Plaza Verde Dr to 2,300 LF west of Sharmon Rd. The project was a part of NHCRWA’s (Authority) 2025 water supply system plan, a multi-year project which will carry water from the City’s Northeast Water Purification Plant (NEWPP) to a new SH 249 Regional Pump Station and Storage Facility. The project faced several key challenges: (1) multiple tunnel crossings of BW8, CPE high voltage transmission lines/towers, and gas/petroleum pipelines (2) crossing of the active Woodgate fault, (3) multiple private properties and recent developments impact. During the initial project phase, A+ Services conducted a Route Study to assess the feasibility of various alignments. As a result, A+ Services obtained approval from the Authority with a recommended final alignment which shortens BW 8 tunnel crossing from 2,000 LF long at a skewed angle to 500 LF long at an optimal perpendicular angle while minimizing impact to private properties and avoids impact to the recent developments.
