ICPRB and Washington Metro Water Management

Wastewater and water supply planning and management in the Washington, D.C., metropolitan area is fragmented among local, state, and Federal governments and agencies. The writers review the background and current status with the purpose of showing the positive role that can be played by the Interstate Commission on the Potomac River basin (ICPRB). The paper details several examples of technical assistance and coordination provided by ICPRB: (1)The Sewer Expansion Simulation (SES), an interactive computer program developed by ICPRB to guide users in the preparation of alternatives for satisfying needs for sewage conveyance and treatment capacity; (2)studies of the use of raw and finished water interconnections among the major water supply systems to meet peak summer demands; and (3)the use of risk analysis during a 1977 drought to guide in the operation of the reservoir source for one of the major water supply systems in the metropolitan area.
