Water Conservation
It's always important to save water in our dry climate, and Carlsbad has long been a leader in water conservation, desalination and recycled water. If you're looking for more ways to save, these resources can help you get started.

Questions and answers
The Carlsbad Municipal Water District is currently at a stage one “drought alert” level, which calls for voluntary cutbacks in water use. To see which water district serves you, refer to this map. View a complete list of water rules.
Carlsbad is served by three water districts, and rules differ according to the needs of each district. All districts work together to coordinate wherever possible to make it easy for the public to know the rules.
The Carlsbad Municipal Water District is a subsidiary district of the City of Carlsbad, delivering water to about 85% of the city. The southern part of the city is served by the Olivenhain Municipal Water District and the eastern area is served by Vallecitos Water District. Find your water district.
Water planners forecast growth based on state and regional projections, including the amount of housing the city is required to provide. This information is included in long term water resource planning. These plans consider projected water savings from strict new conservation measures required of all new development, ongoing conservation efforts and the continued expansion of water recycling.
Recycled water can be used for landscape irrigation and certain industrial processes. Carlsbad recently doubled the capacity of its recycled water plant, which provides added water reliability for businesses.
Under the Carlsbad Municipal Water District’s rules, if a Drought Response Level 5 is declared, no new water meters would be approved, which would limit new building in the city.
The desalination provides about 17 percent of Carlsbad’s water supply, but conservation still needs to be a way of life in our dry climate. Our region is better prepared than most to withstand a prolonged drought because we have invested in many different water sources.
Water rates can go up when less water is used. This is because water rates are set according to the actual cost to provide water service, and some of these costs are fixed, meaning they are the same regardless of how much water is used.
The water district conducts “cost of service” studies to determine the cost to provide water service, and rates are set based on that. Other factors influencing water rates are infrastructure needs and the cost to buy imported water, which is the biggest expense in your water bill.
The Carlsbad Municipal Water District Board votes on any potential rate increases at public meetings. All customers will be notified by mail before rate hearings with meeting details and instructions for providing public comment.
The water district has the power to impose fines of up to $500 per day, but awareness and education are the first steps.
To report water waste in the CMWD service area, call 442-339-2722 or email water@carlsbadca.gov. Report any observed over-watering, sprinkler overspray or other violations with as much detail as possible, including street address and time of day.
Many parks, street medians and homeowners’ association landscaped areas are irrigated with recycled water, a drought proof supply that is not subject to current water use restrictions.
Did you receive a courtesy notice on your door? This is to make you aware of something a staff member witnessed on your property and provide conservation tips.
The City of Carlsbad is doing its part to help save our precious water resources. For example:
Parks
- Recycled water is used at half of all of the city’s community parks, including the five largest.
- The city uses dozens of “smart controllers” and water efficient irrigation systems and is continuing to upgrade its other irrigation controllers/systems.
- The city has seven artificial turf athletic fields and one artificial turf event area at its parks.
Fixtures
- About three-fourths of city facilities have low flow toilets. The city has plans to replace 44 more with low flow models and 106 with dual flush valves.
- Waterless urinals have been installed in restrooms where increased maintenance is not an issue. The city plans to replace 35 additional urinals with waterless models.
- Most city facilities have water saving faucets.
Landscaping
- The city has a water efficient landscape ordinance that establishes requirements for planning, design, installation and maintenance of water efficient landscapes in new construction.
- Drought tolerant plants are used routinely in new landscaping.
- Natural mulch is being used routinely in landscaped planters to retain moisture in the soil.
- Hundreds of broadcast spray irrigation heads have been replaced with more water efficient stream rotor spray irrigation heads.
- Designated decorative grass that is not irrigated with recycled water is being replaced with drought tolerant landscaping.
Recycled water
- Carlsbad currently has the third largest production of recycled water in the region and recently doubled the recycling plant’s capacity.
- The city has approximately 95 miles of recycled water distribution pipeline. This distribution system supplies more than 700 points of connection, including golf courses, hotels and manufacturing businesses.
- Recycled water is also supplied to many Carlsbad parks, facilities, median planters, shopping areas, freeway landscaping and common areas of homeowners’ associations.
Utilities rate increases
On Tuesday, rate changes were approved for water, sewer and recycled water based on results of recent studies to determine the actual cost of providing these services. Keep reading for additional information on what’s changing, why increases are needed and what we’re doing to reduce operating costs.
First, here’s a look at how much a typical single-family home’s bill could increase in the next three years.
Although rates are increasing, Carlsbad’s rates will still remain among the lowest in the region.
Average monthly residential water bill:
Why increases are needed
The main driver of the water rate increase is the increasing cost of purchasing water from the region’s water wholesaler, the San Diego County Water Authority.
About one-third of the cost to provide service is specific to Carlsbad Municipal Water District.
- These costs include things like infrastructure maintenance, repair and replacement and ensuring water quality meets all federal and state standards.
- From 2021 to 2023, construction costs increased 18%, which makes infrastructure repairs and replacement more expensive.
The main reasons sewer rate increases are needed include:
- Rising costs to replace aging infrastructure
- An increase in the costs for wastewater treatment infrastructure at the Encina Wastewater Authority, where Carlsbad’s wastewater is delivered and treated.
Reducing costs
Before we put forward rate increases for consideration, we looked closely at how we can reduce our costs while still providing reliable water service. Here are a few ways we've reduced costs recently:
- Eliminated two CMWD staff positions
- Reducing our planned spending on capital projects
- Focusing on proactive maintenance before costly emergency repairs or replacements are needed (which can cost up to four times as much as planned maintenance)
- Explored new technologies for things like pipeline repair and infrastructure inspections, which can be more cost effective than previous options.
A note on desalination
We’ve received some questions about the Claude “Bud” Lewis Carlsbad Desalination Plant and how that impacts our water rates. The short answer is that although we are proud to have the desalination plant in Carlsbad, it doesn’t equate to lower water bills for our residents. Here’s why:
- While the plant is located in Carlsbad, the city does not own or operate the facility. The Water Authority purchases water at pre-defined prices from Channelside Water Resources, a private company that operates the plant.
- The desalination process is complex and requires a lot of energy, making it expensive. While it provides a critical drought-proof water supply, the water from the desalination plant is actually our region’s most expensive source of water.
- After the water is treated, it is blended with water imported from the Colorado River and Northern California, and distributed. About 17% of Carlsbad Municipal Water District’s water comes from the desalination plant.
Three water and wastewater districts serve the City of Carlsbad. You can view water and wastewater district maps to find out which district provides service to your property.
