ProblemsCrew cleaning storm drain after a storm

Reporting Problem

To report an emergency, please call our Emergency Service Center. This Hotline is available 24-hours a day, 7 days a week. For non-emergencies, please Contact Us.

What An Emergency?

  1. Raw sewage backing up onto your property or into gutter.
  2. Street flooded due to clogged storm drains.
  3. Water pipe broken and water running into the street.
  4. Paint, oil, swimming pool water, or other types of hazardous waste being dumped or washed into gutter or storm drain.
  5. Maintenance-hole cover missing or not sitting correctly on opening.

Sewer Problems

If your sewer system clogs or backs up, problem may not be in sewer line at your home or business.

  • Contact Us before you call a plumber.
  • MUD will come out to determine location of the problem and clear any clogs beyond the owner's connection point. This could save costly and unnecessary plumbing repairs. 

We have crews on duty 16 hours a day, 365 days a year, who will respond promptly. Our service trucks are equipped to open clogged lines. If repairs to City lines are needed, we have construction crews available to handle the problem.

Clogged Storm Drains

Clogged storm drains can cause street flooding and traffic hazards.

  • Please keep storm drains clear of debris.
  • Sweep and dispose of leaves and garden debris from gutter and sidewalks; don’t let it clog drains. 
  • If the drains get clogged during a storm and your street and gutter begin to flood, Contact Us. We will send a crew to clear the storm drain as quickly as possible.

Water Leak Problems

If you see water leaking into the gutter or street, it may be an indication of a broken pipe.

  • First, check the nearest address to see if your water provider is the City of Stockton. 
    • If it is, please Contact Us, so we can send a service crew to assess the situation. 
  • If it is not, please contact your provider. 

Even a small leak can be a sign of a larger problem and water is too precious a resource to waste.  Helping avoid waste can save money for everyone.

Illegal Dumping or Cleaning

Please call emergency number as soon as possible if you see someone...

  • washing out construction or painting equipment,
  • dumping oil,
  • emptying their swimming pool, or
  • in any way allowing any hazardous waste into the gutter or storm drains, 

Water that goes into the gutter flows through the storm drain and into the Delta without being treated.  We need to stop the hazardous waste before it gets into the Delta.  Each call is treated confidentiality.  Illegal dumping is a serious matter.

Missing or Improperly Set Maintenance Hole Covers

If you see a missing maintenance hole cover, or one sitting incorrectly, please call Contact Us as soon as possible. Your call could prevent serious injury and unnecessary property damage.

Water Waste

Water is a precious and vital resource for us all and should never be wasted. Report water waste by calling our Water Conservation Hotline


All contact numbers can be found on Contact Us.
