The results of recent studies to determine the actual cost of providing water, sewer and recycled water service were presented to the City Council Tuesday, along with proposed rate changes that will be considered at a public hearing April 22.
If approved, Carlsbad’s rates would still be below the county average: A typical Carlsbad resident would see their monthly water rates go up about $36 over the next three years and sewer rates $26 over that same timeframe.
- 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.
- The need to replace aging infrastructure is the main reason for the increased sewer rates.

Changes are also proposed for how charges are broken out on water bills, with a new line item showing the cost of purchasing water, which is a passed through charged to local customers from the San Diego County Water Authority. Water rates would also be simplified under the proposed plan. Currently customers can pay up to three different rates, depending on how much water they use. The new rate structure has just two tiers to simplify bills.
Information about the proposed changes is being mailed to all customers impacted. The city’s website also has details about the proposed rates and how to protest or object to the changes.
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.
