INFORMATION MEETING NOTICE
FOR
PROFESSIONAL ENGINEERING SERVICES PROVIDERS
MARCH 20, 2008
9:00a.m. to noon, Room 409
5000 Overlook Avenue, SW
Washington, DC 20032
GENERAL
The District of Columbia Water and Sewer Authority will require a variety of professional
engineering services for its Long Term Control Plan (LTCP) implementation and will hold an
information meeting for firms interested in being considered to provide these services. The
Authority will present its organization, program and schedule, and entertain questions and
comments at the meeting and for a short period following the meeting.
The Authority will be moving into the detailed design and construction phases of its LTCP for
the District’s combined sewer system. The LTCP comprises a system of deep tunnels, diversion
structures and sewers and ancillary facilities to control combined sewer overflows (CSOs) to the
Anacostia and Potomac Rivers and Rock Creek.
The Authority anticipates that agreements for these services will be subject to a Fair Share
Objective for Minority and Women Business Enterprises (MBE and WBE) participation. The
program requirements are defined in the USEPA’s “Guidance for Utilization of Small, Minority
and Women’s Business Enterprises in Procurements Under Assistance Agreements – 6010, 1997
Page 1 of 13
Edition”. The MBE and WBE participation will be 28 percent and 4 percent, respectively as a
minimum.
PROJECT BACKGROUND
The Authority is implementing its LTCP to control CSOs to the Anacostia and Potomac Rivers
and Rock Creek. The schedule for implementation of the LTCP is included in a Consent Decree
between the United States, the District of Columbia and the Authority.
Recently, the United States Environmental Protection Agency (EPA) added an effluent limit for
total nitrogen (TN limit) to the NPDES permit for the Authority’s advanced wastewater
treatment plant at Blue Plains. As part of its plan to meet the new TN limit, the Authority is in
the process of modifying the LTCP and the Consent Decree to accommodate wet weather
treatment requirements associated with meeting that limit. The facilities that make up the
modified LTCP, as proposed by the Authority, are shown on Figure 1 (attached).
As shown on Figure 1, the LTCP comprises a tunnels system designed to capture, convey and
store combined sewer flows.
The LTCP includes a tunnels system for each receiving water (Anacostia River, Rock Creek and
the Potomac River) together with appurtenant facilities that include drop shafts and overflow
structures, diversion structures and sewers, pumping stations, selected sewer separation and
outfall consolidation projects, a wet weather treatment facility at Blue Plains and District-wide
retrofits for Low Impact Development (LIDR). The tunnels system for the Anacostia River is
the largest of the three systems and extends from Blue Plains, along the Anacostia River and into
the Northeast Boundary Area. The principal function of the Northeast Boundary Area tunnels is
to convey storm flows out of the Northeast Boundary Area to control chronic surface flooding.
However, these tunnels also provide part of the total CSO storage capacity of the tunnels system.
The overall tunnels system is being designed to operate as a passive or gravity system. Flows are
diverted into and out of the tunnels system by gravity without the use of control gates or electromechanical devices. Weirs and orifices are used to control flow rates and water levels. Flap or
tide control type gates are used to control reverse flows and to prevent river waters from entering
the system.
The Consent Decree was effective March 23, 2005, and the schedule requires implementation of
the LTCP over a 20 year timeframe. Activities in the schedule include facility planning, design,
construction and placing facilities in operation.
Principal milestones included in the Consent Decree are summarized as follows:

ANACOSTIA RIVER PROJECTS
The Authority is in the process of completing the Facility Plan for the Anacostia River projects.
Most elements of the tunnels system for these projects have been established as part of facility
planning. A public participation program was conducted as a part of the modification process for
the LTCP and Consent Decree.
The current tunnels system alignment is shown on Figure 2 (attached). As shown on Figure 2,
this system comprises four principal tunnels as follows:

The Blue Plains Tunnel (BPT), which extends from the Authority’s advanced wastewater
treatment plant at Blue Plains, along the Potomac and Anacostia Rivers, crossing under
the Anacostia River and terminating at the Authority’s Main Pumping Station. Existing
combined sewers that convey dry weather flow to the pumping station will be diverted
into the BPT. Additionally, there will be a structure on Bolling AFB to allow overflows
from the tunnel to be discharged to the Potomac River,

The Anacostia River Tunnel (ART), which extends from a junction shaft on the BPT at
Poplar Point, along and under the Anacostia River to a two-shaft complex just south of
RFK Stadium. Shafts on the tunnel will be used to connect diversions from existing
combined sewers to the tunnel and there will be overflow structures at the two-shaft
complex adjacent to RFK Stadium,

The Northeast Boundary Tunnel (NEBT), which will extend north from the end of the
ART and swing around into Mt. Olivet Road, down New York Avenue and turn to pass
under the railroad yards on the westerly side of New York Avenue. A drop shaft at Mt.
Olivet and West Virginia Avenues will collect flow from the combined sewer system in
that area, and;

The Northeast Boundary Area Branch Tunnels, which comprise a system of three tunnels
to collect flow from the combined sewer system in that area to provide sewer capacity for
flood relief.
Contract divisions have been established in the facility plan for the Anacostia River Projects as
shown on Figure 3 (attached) and a profile of these tunnels is shown on Figure 4 (attached).
Based on the facility plan findings, the Authority does not anticipate considering major changes
to the designs developed in the facility plan for the Anacostia River projects tunnel system.
The next steps for the Anacostia River projects will be to advance the planning and designs
already established and prepare contract documents for construction of the various contract
divisions.
The Authority anticipates following the general implementation approach of the Anacostia River
projects for the Rock Creek and Potomac River projects.

ENGINEERING SERVICES REQUIRED
The Authority expects to provide staff dedicated to implementation of the design and
construction phases of the LTCP project.
Authority staff will administer program consultants, individual design and construction manager
consultants and construction contracts along the lines of the organization shown on Figure 5
(attached).
As shown on Figure 5, engineering design and construction management services for the various
projects in the program will be provided to the Authority through a team of Program Consultants.
The Authority plans to engage the Program Consultants as the first step in the engineering
services procurement process. Thereafter and in parallel with the Program Consultants
procurement process, the procurement process for design consultants will proceed. Procurement
of services for construction management will occur at the appropriate time in the project cycle.
The Authority will enter into professional services agreements with each consultant selected.
However, the Authority will utilize the Program Consultants in the administration, guidance and
monitoring of design and construction manager consultants. Overall, the Program Consultants
will have the responsibility to develop and implement the Authority’s objectives to obtain
unified and coordinated designs, criteria, policies, procedures, guidance, instructions and
technical and quality review of design and construction manager consultants and construction
contractors. Roles and responsibilities for the principal activities to be performed by the
Program Consultants are summarized in Table 1 (attached).
Firms may submit for any individual procurement as an:

Individual firm,

Joint venture or;

A project team of prime(s) and subconsultants.
However, firms submitting, under the above combinations, for services as Program Consultants
must submit as either the Program Manager or the General Consultant for Tunnels and
Geotechnical Engineering. Firms included in a submission for Program Manager, with the
exception of MBE/WBE firms, may not be included in the submission for Tunnels and
Geotechnical Consultant; and vice-versa.
Firms may submit for any or all individual procurements as design and construction manager
consultants as they occur. However, firms serving as or a part of the Program Consultants
organization may not submit for individual design and construction manager procurements.
