Sallisaw Raw Water Intake Structure & Pump Station

Project Description

This project utilized innovative bridge construction techniques to design a new raw water intake structure and pump station on Brushy Creek Lake for the City of Sallisaw, Oklahoma. Its current capacity is 6.0 million gallons per day (MGD), and replaces an existing raw water intake structure and pump station that possessed both capacity limitations and structural deficiencies. The raw water intake structure incorporates three (3) inlet ports to allow the withdrawal of the highest quality water from the lake. Each inlet port has an intake screen to protect both the pumps and existing fisheries within the lake. The piping and valving were designed to facilitate the future replacement of pumps and increased capacities of up to 10.0 MGD, thus accommodating the 50-year design period. The project also included a Chemical Building that houses potassium permanganate chemical feed equipment to address seasonal taste and odor problems inherent to the water supply. Hawkins-Weir Engineers provided study, design, construction observation, and construction management services for the project.
