DC WASA Hosts Industry Outreach Meeting on Combined Sewer Overflow Long Term Control Plan Tunnel Program

October 05, 2009

As part of its Combined Sewer Overflow Long Term Control Plan (LTCP), DC WASA will hold an Industry Outreach Meeting on Friday, October 30, 2009, at the Blue Plains Advanced Wastewater Treatment Plant to present project goals, the procurement process, and contract terms and conditions for the Blue Plains Tunnel design-build project.

In 2002, DC WASA prepared a Long Term Control Plan (LTCP) for the District’s combined sewer system to reduce Combined Sewer Overflows (CSOs) and comply with the Clean Water Act. The LTCP provides for the control of CSOs to the Anacostia and Potomac Rivers and Rock Creek in Washington, D.C. Following EPA approval of the LTCP, the United States, the District of Columbia, and DC WASA entered into a Consent Decree to implement the LTCP, which includes a series of underground storage and conveyance tunnels. The total project cost is projected to be $2.2 billion.

These tunnels will be approximately 23 feet in diameter and approximately 100 feet underground. By the year 2025, the fully constructed CSO program will reduce combined sewer overflows to local waterways by 96% overall, and by 98% in the Anacostia River alone.

The Blue Plains Tunnel will be the first of four major tunnel sections to be constructed. The tunnel will begin at DC WASAs Blue Plains Advanced Wastewater Treatment Plant, run north along the Potomac and Anacostia Rivers, cross under the Anacostia River at Poplar Point, and end at DC WASAs Main Sewage Pumping Station.

At 23,600 feet, the Blue Plains Tunnel is the largest of the contracts with an estimated construction value of $250 to $300 million.

In addition to presenting procurement and contract-related information, the meeting will be an opportunity for attendees to ask questions about the project. Following the Q&A, there will be time for networking with other firms in attendance.

The meeting will be held on Friday, October 30, 2009, from 10:00 am to 12:00 noon at DC WASA’s Central Operations Facility (on the Blue Plains Advanced Wastewater Treatment Plant site), 4th Floor, Room 409, 5000 Overlook Avenue SW, Washington, D.C. 20032.

To make reservations, call Ms. Melva Massey at (202) 787-2363 or send an email to mmassey@dcwasa.com. Reservations should be made no later than Wednesday, October 28, 2009. Space will be limited; therefore, firms attending are limited to attendance of two (2) persons. Reservations will be given preference should space become limited.

Persons attending will need to obtain a visitor’s pass at the security building located at the plant’s entrance. Please allow 30 to 45 minutes to complete this process. The Central Operations Facility (COF) building is located immediately to the right of the entrance gate. Parking will be available in designated areas around the building. For more information on the overall program, please reference the link below.

DC Water will be doing construction as part of a sanitary sewer rehabilitation project on Clara Barton Parkway in Maryland from Sept 8 - Oct 10, 2025, which may cause delays inbound near the I-495 Beltway interchange. One lane will be closed in the work zone to reline an 800-foot section of the sewer line, known as the Potomac Inteceptor. Access to the inner and outer loops of the Beltway will remain available. Additional lane closure may be necessary intermittently through Oct 31, 2025.
