The Grimes Brief

Guide · Water

Water and sewer in Grimes: the city runs it, here is how to connect.

Unlike some suburbs that buy water wholesale, Grimes runs its own water utility, from the wells to your tap. Here is what that means for setting up and paying.

The short version

The City of Grimes provides both water and sewer. It draws from its own wells and runs two treatment plants. To start service, contact City Hall at 515-986-3036; bills are paid through the city's online system.

The utility
