Catch Basins

Storm Drains

The City of Beaverton has over 8,000 Storm drains. These act as inlets into the Storm conveyance system. Typically these include a grate where the water enters and a holding area in the bottom of the storm drain that allows water to pool-giving sediment, debris and other pollutants the chance to be caught before entering open water. All water that enters the storm drains in Beaverton will eventually drain into the Tualatin River. The wildlife that we see in and around the Tualatin watershed also lives in our Storm conveyance system. Your City crews work to ensure that water entering the system and traveling downstream is clean and safe for everyone to enjoy.

Every person can play an important role in preserving our water resources and assist with having clean water for everyone. This includes not doing any dumping of paint, chemicals, oils, or any other illicit discharge in the Storm conveyance system. Car wash soap is also discouraged. The only permitted discharges into the storm system are rainwater, groundwater, surface drainage, roof drainage and De-chlorinated water from yard fountains, ponds or pools. When in doubt, think of the catch basins as fish tanks. If you wouldn’t dump it into a fish tank, it shouldn’t go in a storm drain. Know that all of the water that enters the catch basins will go directly into a stream, creek, or river.
