휴스턴시가 Chelford시 폐수처리 플랜트에서 Braes 상류 폐수처리 플랜트까지의 시설에서 발생한 폐수유량 전환을 위한 전문 설계서비스를 제공하는 데에 Lockwood, Andrews & Newnam(LAN)사를 선정했다.

이번 프로젝트는 휴스턴시가 진행하고 있는 폐수 리프트스테이션 시설 통합을 통해 폐수 인프라를 향상시키는 프로그램의 일환이다.

 

 

 

The City of Houston has selected Lockwood, Andrews & Newnam, Inc. (LAN), a planning, engineering and program management firm, to provide professional engineering services for the diversion of wastewater flows from the Chelford City Wastewater Treatment Plant to the Upper Braes Wastewater Treatment Plant.

 

The project is part of the City of Houston's ongoing program to improve wastewater infrastructure by consolidating its wastewater lift station facilities. Currently, a network of collection systems consisting of gravity sewers and lift stations serves the west side area, sending flows to Chelford City. The City of Houston has a contract with Chelford City to treat this sewer flow.

 

Flow diversion to the Upper Braes Waste Water Treatment Plant will require the installation of a 54- to 60-inch sewer tunnel, deep gravity collection lines, and new or modified lift stations and force mains. As part of the project, LAN will evaluate several flow diversion alternatives by gravity sewers or pumping stations or its combination.

 

In addition, alternatives for sewer line routing and lift station location will be evaluated. Finally, a lifecycle cost analysis will be performed to determine the most economical option for the City. Design of the $15-million project is expected to be completed in November 2016 with construction anticipated to be completed in November 2018.
