ABOUT THIS PROJECT
Dredging included both maintenance and deepening work in Basins 1-4 and removal of silts from sediment traps in Basins 1 & 6. The work also involved the Rehabilitation of the Oakley Confined Sediment Basin by raising the existing berm by 10 feet, which required over 769,000 CY of earthwork.
Dredge material was excavated and pumped through 9 to 10 miles of discharge pipeline, placed to the Oakley Confined Sediment Basin.
To save the city money, improve efficiency and better manage environmental concerns, the entire dredge and booster pump stations were electric.
This project will increase the water storage capacity for the City of Decatur by 30 percent, while also meeting future demands and improving tourism with greater recreational opportunities.
