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.

Save water with new virtual program

Carlsbad has long been a leader in water conservation, recycled water and desalination, and now a new program is available for those who want to find ways to save even more water. Metropolitan Water District of Southern California is offering a free virtual home survey, where an auditor will meet with residents and share key information and training, including:

  • Recommendations for reducing water waste
  • A review of indoor devices to check for leaks, damage or inefficiencies
  • Evaluation of the home’s water meter to check for leaks
  • Irrigation controller training and zone/station information
  • Identification of irrigation problems
  • Review of issues that contribute to higher water use, such as valve malfunctions, high or low pressure, sprinkler misalignment, poor draining, breaks and leaks, and runoff
  • Rebate information

Surveys are scheduled on a first-come, first-served basis, and funding is limited. To request a survey, complete an online application.
