This project, completed in early 2024, consisted of the construction of a large-diameter water transmission line to connect the Northeast Water Purification Plant (NEWPP) on the western shore of Lake Houston to existing northside City water lines as well as to the North Harris County Regional Water Authority’s (NHCRWA) 84" water line at Beltway 8 and IH-45. This 108" water line, known as the Northeast Transmission Line (NETL), provides shared surface water capacity for the City of Houston and the NHCRWA. 99E-1 is one of fourteen segments that comprise the entire NETL alignment and was constructed within easements adjacent to and under several Harris County Flood Control Channels. This project was the second to final alignment prior to connecting to the NHCRWA’s 84" line and contained a major crossing of the Union Pacific Railroad and the Hardy Toll Road.
Five Companies completed approximately 5,910 LF of 108” water line by a combination of open-cut and tunneling methods and 22 LF of 66” water line by open-cut methods, as well as removal and replacement of pavement, existing utilities, and drainage infrastructure. The project also included connections to other NETL projects, including two proposed 108” water line projects and a proposed 66” water line project.
