HOUSTON — Lockwood, Andrews & Newnam Inc. (LAN) announced that the city of Houston selected the firm to provide professional engineering services related to the diversion of wastewater flows from the Chelford City Wastewater Treatment Plant to the Upper Braes Wastewater Plant, according to a press release.

The project is part of Houston’s ongoing program to improve the wastewater infrastructure by consolidating its wastewater lift station facilities, stated the release.

The city has a contract with Chelford City to treat the sewer flow from a network of collection systems consisting of gravity sewers and lift stations serving the west side area, continued the release.

Flow diversion to the Upper Braes Waste Water Treatment Plant will require a 54- to 60-inch sewer tunnel, deep gravity collection lines and new or modified lift stations and force mains to be installed, reported the release.

LAN will evaluate several flow diversion alternatives by gravity sewers, pumping stations or combinations as part of the project, noted the release.

“With the new collection system, the city will have a reliable infrastructure to serve its residents for the foreseeable future,” said Stephen A. Gilbreath, P.E., LAN senior associate and team leader.
