The RiverRenew Wastewater Project modernizes Alexandria’s aging combined sewer system and addresses a longstanding environmental challenge for the historic city. By creating new infrastructure to manage wastewater and stormwater during wet weather, the project will help protect Alexandria’s waterways and reduce the release of untreated sewage into the Potomac River and surrounding waters. BILCO supported this initiative by providing customized floor doors that give maintenance personnel access to critical mechanical and ventilation equipment throughout the system. Designed for the demanding conditions of the project, the doors make access safer and easier while helping protect the equipment below.
"The hatches are required to withstand AASHTO HL-93 truck wheel loading, a common industry standard. Despite the large size of some of the hatches, they are relatively lightweight and easy to open and close. The hatches also include integrated drainage components that divert surface water away from the spaces below, helping to protect equipment. Anything that makes access easier and safer is appreciated by our staff.”
