Project Description

Client: City of Houston

Location: Houston, Texas

The Northwest WWTP has an average day capacity of 18.0 mgd and serves the developed area of Houston surrounding the IH-610 and US-290 intersection. The original construction dates back to the 1960’s and most recent update was in the late 1980’s. A substantial rehabilitation was required to maintain the integrity of the facility. The $20,000,000 project was conducted with two design and construction packages.

Package I included evaluating the evaluation of the odor control system, rehabilitation and/or replacements of the scum removal system, rehabilitation and/or replacement of aeration basin slide gates, replacement of the clarifier drain valves, hydraulic evaluation of the clarifier performance, structural evaluation of the chemical building, maintenance building, administration building, and maintenance building foundations, and replacement of the waste sludge pump station. KIT conducted the clarifier drain valve replacement, clarifier hydraulic evaluation, clarifier condition assessment and building repairs.

Package II includes the replacement of the clarifier mechanisms, replacement return activated sludge pump stations, replacement of the coarse air diffusers in aeration basins 6 thru 10 and installation of a new non-potable water system network.
