PROJECT OVERVIEW

The City of Houston was responsible for constructing 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-inch water line at Beltway 8 and IH-45. This 108-inch 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. 99E-1 is the second to final alignment prior to connecting to the NHCRWA’s 84-inch line and contains a major crossing of the Union Pacific Railroad and the Hardy Toll Road.

SERVICE DETAILS

Our team worked as the Engineer of Record for approximately 5,900 Linear Feet of 108-inch Water Line to connecting between two other NETL alignments, requiring extensive coordination between other consulting engineers and the City of Houston.

Our team prepared the construction drawings, technical specifications, and contract documents, which included the 108-inch water line design. The design included three HCFCD channels, two roadways, and a Hardy Toll Road/UPRR tunnel crossing designs. The design also included extensive utility relocation and property owner coordination. Finally, pavement removal and replacement and utility relocation design were required at multiple facilities along the alignment, including FedEx and Frito Lay.
