Sanitary Sewer

Whether you're flushing the toilet, washing clothes, having a shower, or washing the dishes, we send a significant amount of water down the drains in our households each day.

The District's sanitary sewer system is a complex network that transports and treats wastewater before it is released back into the environment.

Unflushables

Everything you put down the drain or toilet must go somewhere.

Preventing problems in your pipes

The water and other materials that go down the pipes are processed and then released back into the environment. Sinks and toilets are not intended to be disposal systems for garbage or chemicals.
