Division D is located on the Joint Base Anacostia Bolling (JBAB) military facility. The project includes a Diversion Chamber constructed around the Potomac Outfall Sewer; Overflow Structure which is to convey flow to the Potomac River; and an Odor Control Facility. The diversion chamber will divert flow to a tunnel shaft through the tunnel to the Blue Plains Advanced Wastewater Treatment Plant. The Overflow Structure will allow controlled overflow from the tunnel to the Potomac River while providing solids and floatable control with a combination of fixed screens and weirs. The two structures are reinforced concrete with landscaping and aesthetic treatments to meet JBAB requirements including a new seawall, ornamental fencing and pavers for a Potomac River overlook.
L. S. Caldwell & Associates, Inc. (LSC) has responsibility for the development, implementation, and monitoring of the Fair Share Objective initiatives for the District of Columbia Water and Sewer Authority’s (DC Water) Clean Rivers Project. This $2.6 billion program is the result of a Consent Decree signed by the District of Columbia, the Environmental Protection Agency, the Department of Justice. DC Water was required to clean up the Anacostia and Potomac Rivers by 2025. Seven discrete portions of the work, called Divisions, are underway; totaling approximately $819,368,566.00. Twelve Divisions are anticipated.
In addition to compliance program development, LSC’s role includes:
- Introduction of an online reporting system that tracks usage of minority-owned and women-owned businesses on the projects, as well as online collection of employment data on behalf of DC Water.
- Outreach to protected class businesses is also fundamental to its mission, as is ensuring compliance with Davis Bacon Act requirements.
- Implementation of DC Water Works Interim Employment Program during development of the Permanent Employment Program.
