Municipal Utilities Department 

The Municipal Utilities Department (MUD) is responsible for the operations of three water 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.

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

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

Work performed by MUD is in accordance with applicable regulations and responsible business practices. Monthly Operations and Maintenance Report (MOMR) is prepared that details department operations.
