East Water Purification Plant Expansion to 350 mgd

CLIENT: City of Houston, Texas

CONTRACT TYPE: Sub-Contract to J.F. Thompson, Inc.

PROJECT DESCRIPTION: Pipe Stress Analysis for the Plants 1 and 2 High Service Pump Station expansion to 191,000 gpm (275 mgd) at the East Water Purification Plant (EWPP) to achieve a firm reliable capacity of 350 mgd.

YEAR COMPLETED: 2000

CONSTRUCTION COST: N/A - Study

SCOPE OF WORK: KGI was responsible for performing the pipe stress analysis to evaluate the effect of thermal forces, weight and pressure, restraints, effect of support, anchor and terminal movements on the existing and proposed piping systems. The study was performed to ensure the piping system is adequately supported and anchored for the proposed design conditions.

The Caesar computer program marketed by COADE Engineering Software was used to perform the pipe stress analysis. The study recommendations included type of pipe supports to be used, locations of proposed pipe supports and expected loadings, locations of restraints and expansion joints and expected loads to the pump nozzles. In addition, the study identified the type of temporary pipe supports that could be used during construction to handle the expected loads from the piping system at different construction phases.
