Site/Civil Occoquan Dam Facilities Upgrade > Projects > Occoquan Dam Facilities Upgrade KEY CHALLENGES & PROJECT DETAILS Decommissioned and removed three electrical hydropower generation turbines for the Occoquan Dam Reservoir Facility. Rebuilt the Powerhouse with a Water Control Tower which accommodates two new Motor Control Centers and distributes power throughout the facility. The new 84-ft. tall Water Control Tower controls debris from the reservoir, alleviates flooding, and enables the Authority to withdraw additional water during droughts. Installed three steel bulkheads on the front of the dam to serve as a temporary barrier between 70-ft. high wall of water and Corman crews. Designed three 12-ft. wide dam intake covers up to 22-ft. high to resist up to 90-ft. depths of water pressure. PROJECT DETAILS: Project Owner: Fairfax Water Location: Occoquan, VA Close
