Municipal Utilities Department 

The Municipal Utilities Department (MUD) is responsible for the operations of three utilities important to everyday life: water, wastewater, and stormwater. You might not think about your clean drinking water source or where the water goes when you flush a toilet — but we do, every day.


At MUD, we are committed to protecting the environment and providing:

  • Stormwater system that decreases the risk of street flooding
  • Disposal of carefully treated wastewater
  • Education on water conservation and pollution prevention
  • Environmental stewardship
  • Projects to improve the quality of our waterways, lakes, and the Delta
  • Safe drinking water
  • Quality customer service

Work performed by MUD adheres to applicable regulations and responsible business practices.
