Prepared by the Border International Water Quality Standards Committee within the Standards Development Council of the Environmental and Water Resources Institute of ASCE

Comprehensive Transboundary Water Quality Management Agreement with Guidelines for Development of a Management Plan, Standards, and Criteria, ANSI/ASCE/EWRI 33-23, serves as a comprehensive framework designed to assist riparian governments in effectively managing shared water resources. This agreement offers practical guidance for national and state governments, as well as other stakeholders involved in establishing water quality standards for sustainable management of transboundary water resources.

Drawing inspiration from the successful Delaware River Basin Compact, which has been instrumental in resolving interstate conflicts related to shared water resources, this standard covers a wide array of topics essential to water resources planning, including administration, water quality and allocation, financing, and dispute resolution. Emphasizing the importance of data sharing and cost apportionment among parties, the standard is adaptable for use by all parties sharing a common watercourse. In addition, it provides clear definitions of key terms, delineates roles and processes, and includes appendixes offering guidance on developing water management plans, as well as water quality standards and criteria.

ASCE 33-23 is an invaluable reference for environmental engineers, infrastructure engineers, and professionals engaged in water governance, sustainability, geopolitics, and other disciplines with a vested interest in addressing the complexities of transboundary waters. It offers comprehensive insights and practical solutions for effective water resource management across borders.
