Rock Rapids Municipal Utilities' Wastewater Department oversees the operation of the Wastewater Treatment Plant. Sewer charges are based upon actual water usage.  

Treatment of raw sewage is regulated by the Iowa Department of Natural Resources. We are continually upgrading our system to meet these requirements. In the slide show above, wastewater is shown flowing under the ultraviolet light during the treatment process.

Be sure everything you are putting into the sewer system is flushable. Check out this flyer for more information.
