Cracked Wall Replaced in a Single Day at Alabama WTP.

A 50-year-old baffle wall showing a significant crack forced a water treatment plant permitted for 3.3 million gallons per day in Moulton, Ala. to stop production while crews worked to replace the wall. Total production days lost: 1.

Garver prepared a design to replace the failing wall with a new fiberglass-reinforced plastic (FRP) wall utilizing FRP panels. Garver scheduled with a local contractor for the installation and, together, they were able to minimize the facility’s down-time, which the owner utilized to remove accumulated sludge from the treatment plant.

Sludge removal


Construction activities began on a Sunday morning to replace the failing wall, and the contractor was ready to install the new FRP panels by early afternoon after demolition and removal of the existing wall. All construction was finished late Sunday evening, enabling the owner to activate the WTP in less than 24 hours from initially stopping the facility’s production.

“This project successfully replaced a failing wall and returned to normal plant production in less than one day, saving the owner extended purchase water expenses, while also allowing the owner to remove sludge accumulation and improve the overall plant efficiency," said Garver Project Leader Michael Malires, PE.

“Upon completion of this project an amended invoice was received, which saved the Water Dept. $15,300.00,” said George Brackin, chairman of the Moulton Water Works Board. “Never before have we been the recipient of a reduced price after all contracts were finalized.  The contractor was secured by Garver for us and our Board continues to have complete confidence in Garver to keep our best interest first at all times.”
