Clean Water Services is a public utility committed to protecting water resources in the Tualatin River Watershed. Nearly 500,000 customers enjoy clean water and healthy rivers and streams through innovative wastewater and stormwater services, flood management projects, water quality and stream enhancement projects, fish habitat protection, and more. Our services are crucial to the region's public health, environmental protection, and economic vitality. Clean Water Services operates four wastewater treatment plants and 39 pump stations. We also work with our 12 member cities to build and maintain the public sanitary sewer and surface water management system.
Clean Water Services Design and Construction Standards describe the administrative and technical requirements for the design and construction of sanitary and surface water management systems that are built as part of residential or commercial development.
Clean Water Services and its partners completed the Low Impact Development Approaches Handbook to promote sustainable development practices for Tualatin River Watershed in 2009. Low Impact Development Approaches (LIDAs) can maximize a site's potential by reducing or incorporating the area needed for stormwater management and water quality treatment while protecting natural resources and habitat.
The goal of Oregon Department of Environmental Quality's Underground Injection Control Program is to protect groundwater resources primarily used for drinking water from contamination by unauthorized use of UIC systems (also referred to as injection systems). A UIC system is a device that places fluids below the ground. Most UIC systems in Oregon are shallow and widely used to dispose of stormwater, including rainfall runoff and snowmelt, from properties, streets and parking lots owned and operated by public or private entities.
