WTP High Service Pump & Header Improvements

Project Description

The high service pump header at Maumelle’s water treatment plant is a bottleneck where a failure could inhibit the Utility’s ability to provide water to their customers. By the Spring of 2015, corrosion of that header had reached an advanced state. The Maumelle Water Management Utility had legitimate concern that failure along that pipeline was imminent. This project consisted of multiple improvements to the high service pump room at the Maumelle Water Management Water Treatment Plant (WTP). The project consisted of the removal and replacement of existing piping, valves and appurtenances, connections to existing piping, pump room demolition, and the installation of a new high service pump and clearwell access. The project also included the construction of a new equipment access door to the high service pump room and extension of the existing monorail hoist beam. Construction scheduling and completion within the Client’s allowable downtime were critical components to the overall success of the project as one half of the WTP’s capacity was required to be taken offline during construction. Hawkins-Weir Engineers provided construction management and periodic inspection to ensure successful completion of the project within the Client’s scheduled downtime.
