Assessing the state's existing water and sewer systems.

HB 1690 requires Washington's Department of Ecology and Department of Health to jointly conduct a comprehensive assessment of the state's water and sewer systems by June 2027. The assessment will identify critical infrastructure gaps, analyze upgrade costs, and evaluate funding options to address issues like aging systems, septic maintenance challenges, and water quality concerns affecting public health. It directly impacts local governments, water utilities, and residents in communities facing infrastructure limitations, particularly in urban growth areas and small towns. The bill mandates gathering data from cities, counties, health boards, and utilities to inform recommendations for protecting environmental resources and supporting economic development. This assessment aims to provide a data-driven foundation for future investments in water and sewer infrastructure.
