 Wastewater Treatment Plants Renewal and Replacement

CLIENT: City of Houston, Texas

CONTRACT TYPE: Sub-Contract to CDM, Inc.

PROJECT DESCRIPTION: Hydraulic Evaluation of three existing Wastewater Treatment Plants.

YEAR COMPLETED: 2001

CONSTRUCTION COST: N/A (Study).

SCOPE OF WORK: KGI was responsible for performing detailed hydraulic evaluation of three existing wastewater treatment plants - Keegans Bayou, Upper Brays and Greenridge. The plants were flooding during peak flow periods. The purpose of the study was to identify hydraulic bottlenecks, evaluate alternatives and propose improvements to alleviate hydraulic bottlenecks to carry a minimum 2-hour peak flow without flooding. A hydraulic model was developed to simulate the effect of various flow rates on the water surface elevation through the plants. Most of the proposed improvements were implemented by the Client.

The study also identified the effect of water levels on the Aeration System and the Blowers.
