About the Utilities Department 

Carlsbad Municipal Water District provides reliable water and wastewater services for pennies a day, while protecting the natural environment and meeting or exceeding strict water quality requirements. 

Carlsbad Municipal Water District provides water service to most of the City of Carlsbad, but some parts of the city are served by other districts for water and for wastewater. View the maps below to find your provider. For properties in the southern portion of the city, contact the Olivenhain Municipal Water District, Leucadia Wastewater District or Vallecitos Water District (water and sewer) for utility service sign-ups, disconnects, installations and payment arrangements.

Water utility scam alert

The San Diego County Water Authority is warning community members about scams involving people posing as water agency “workers” to gain access to homes. These scams pop up from time to time, so it’s important to stay vigilant.

Carlsbad Municipal Water District employees will routinely take water samples for testing, but employees very rarely need to enter homes. Here are a few things to look out for if you’re approached by someone saying they are a CMWD employee:

  • CMWD employees will always be in uniform, wear a clearly marked ID badge and travel in a vehicle clearly marked with the city seal.
  • CMWD employees will always state the purpose of their visit and carry a business card with contact information.
  • Scammers might try to sell you on a specific commercial product. CMWD employees won’t endorse or attempt to sell any product.
  • We won’t call or visit your home to ask for payment information of any kind, including credit card numbers.

No reports of this activity have been received in Carlsbad yet, however, if you encounter someone who you think may be trying to scam you, call the 24/7 police non-emergency line at 442-339-2197. If you feel you are in danger, always call 9-1-1 immediately.

The Police Department’s website has more information about how to prevent crime around your home.
