City of Pearland –
FM 521Water Plant
Expansion & Rehabilitation

Pape-Dawson provided planning and design for improvements at the City’s FM 521 water plant, a critical facility serving northwest Pearland. The project was completed in two phases at the City’s request.

Phase I added a new 3.0 MG prestressed concrete ground storage tank (GST), yard piping, grading, drainage channel improvements, tie-ins, demolition of an existing 15,000-gallon hydropneumatics tank, and the addition of mixers for the new tank as well as two existing tanks. Special coordination was required to optimize the GST size with limited plant site access to provide the maximum water storage capacity possible per the City’s request (the two existing welded steel tanks are 1.7 MG each).

Phase II required special phasing to bring GST No. 3 online and maintain service while replacing the motor control center (MCC) and generator, adding five VFDs, and replacing three booster pumps. Programming upgrades and fiber optic installation-related improvements were also included. The project also involved coordinating with ongoing water master planning efforts and surface water plant construction to provide coordinated improvement recommendations.
