Johnny G. Martinez Water Quality Improvement

Project Overview

The City of Tempe, Arizona, contracted PCL to perform needed upgrades to the Johnny G. Martinez Water Treatment Plant. In order to meet schedule and budget constraints, PCL worked with the City and the engineer to develop three GMPs for this project. Ultimately, the project included a multitude of upgrades to this 50 MGD facility.

The improvements included a new granular activated carbon (GAC) facility, a new GAC influent pump station, a new generator building, and a new solids-thickening tank. The project also included modifications and upgrades to the existing infrastructure, consisting of the secondary sedimentation and flocculation basins; chemical systems; solids-handling building; and numerous valve, pump and slide gate replacements. The existing plant control system was upgraded from a network of remote terminal units to a state-of-the-art programmable logic control system, allowing a higher degree of automation in the plant.
