Understand my sewer bill

The sewer service charge was established by the City Council in 1962 to pay for the operation and maintenance of the sewer collection system and sewage treatment. All residents connected to the City’s sewer system pay the service charge.

The City provides sewer service to about 50,000 residential and commercial customers. Monthly sewer rates charged to system users (customers) are the primary source of revenue to operate and maintain the sewer system and are used for this purpose. Sewer rate revenue provides funding for operation and maintenance of City-owned sewer collection and conveyance facilities, capital projects, debt service, administration, as well as costs related to prudent long-term operation and financial management of the utility system, such as maintaining adequate reserves and planning for contingencies. Since the City does not operate its own wastewater treatment facilities, sewer rate revenue is also used to pay for wastewater treatment provided by the City of San Diego Metropolitan Wastewater Authority (Metro).

On May 31, 2026, we sent you a letter providing notice that your sewer rate would increase by 9.96% beginning July 1, 2026 (please see Attachment A). We are now writing to inform you that there has been a reduction to the rate increase described in that letter. The reduction is due to recent changes to an agreement between the City of Chula Vista and the City of San Diego relating to Metropolitan (Metro) Wastewater treatment costs, which were previously calculated to increase by 9.96% next year. We recently received a revised estimate from Metro, reducing
the estimated treatment cost increase to 6.95%. Because of this adjustment in treatment costs, the pass-through for Chula Vista customers will be
6.95%, effective July 1, 2026.

For example:
• A customer currently paying $55 per month will
pay about $59 per month.
• On a bi-monthly bill, a current charge of $110 will
increase to about $118.
This updated sewer rate will be reflected on all customer billing beginning invoices for the month of July 2026. A memo detailing the change (PDF) was mailed to residents in May.

For more information, call (619) 476-5380 or email wastewater@chulavistaca.gov.

The Master Fee Schedule 12-200 for the monthly sewer service charges will be adjusted as follows starting July 1, 2026. 

*HCF – Hundred Cubic Feet.
(1) Rates include Sewer Service Charge, Sewer Facilities Replacement Fee but not the Storm Drain Fee.
(2) Sewer Rate Case approved 4/26/22 with rate increases July 1 starting in 2022 through 2025.
(3) On 4/26/22, the City Council approved the passthrough process for wholesale treatment costs pursuant to California Government Code 53756, per Resolution 2022-
093. This resulted in an increase in the sewer rates starting July 1, 2023. Each year Metro treatment costs will be evaluated and actual costs (increases or decreases) will be applied July 1, in addition to the approved rate increases in (2).

Single-family Residential Rates

Fixed Service Charge. The single-family rate has a fixed fee.  

Volume Charge. The variable charge is based on the average winter (PDF) potable water usage and multiplied by the volume charge in the Master Fee Schedule. Water consumption is reviewed between November 1st  and April 30th when most customers turn off their sprinklers and irrigation is at its yearly low.  The winter average is the average of the two lowest consecutive months of potable water used during this period and multiplied by a rate of return to the sewer to account for water not going into the sewer. This amount is multiplied by the volume charge and the same monthly amount is charged from July 1st to June 30th.

Storm Drain Fee. The storm drain fee is a flat fee for all single family residential rates.

Example Calculation for a Single Family Home with winter average monthly water consumption of 7 HCF (hundred cubic feet):

$19.06 (fixed charge) + (90% x 7 HCF x $5.59/HCF) (volume charge) + $0.70 (storm drain fee)

Multi-Family Residential Rates

Fixed Service Charge. Multi-Family Residential fixed fees are based on the water meter size with larger water meters going to larger complexes having higher charges. That annual amount is found in Chapter 12 of the Master Fee Schedule.

Volume Charge. The variable charge is based on the amount of potable water usage each month and multiplied by rate of return to the sewer as detailed in Chapter 12 of the Master Fee Schedule. 

Storm Drain Fee.  Multi-Family Residential fixed fees are based on the amount of potable water usage.

Commercial and Industrial Rates

Fixed Service Charge. Commercial and Industrial fixed fees are based on the water meter size.  Larger water meters have higher charges which can be found in Chapter 12 of the Master Fee Schedule. 

Volume Charge.  The variable charge is based on the amount of potable water usage and strength of sewage each month and multiplied by rate of return to the sewer as detailed in Chapter 12 of the Master Fee Schedule. 

Strength Determination:

There are three classes of sewer strength which is dependent on the level of Biological Oxygen Demand (BOD) and Total Suspended Solids (SS) in the sewage and are evaluated on a case by case basis. Sewage with higher BOD and SS levels requires more treatment and therefore has higher rates.  Descriptions of strength categories are further explained in Section 2 of the PBS&J Report (PDF).

1. High Strength (Typical Average BOD >400 mg/L and SS >400 mg/L) 
2. Medium Strength (Typical Average Values: BOD 200 to 400 mg/L and SS 200 to 400 mg/L)
3. Low Strength (Typical Average Values: BOD < 200 mg/L and SS < 200 mg/L)

Storm Drain Fee.  Commercial and Industrial storm drain fees are based on the amount of potable water usage.

Frequently Asked Questions

How do I calculate my bill?

The sewer bill depends on your water usage and the type of customer you are (single family, commercial, etc.). Details are provided in "Understand my sewer bill".

Why is my bill higher at my new home than my previous home in Chula Vista?

For single family residences, new sewer usages and rates go into effect July 1 of each year and remain the same for the year.  Please see "Understand my sewer bill" if you are not a single family residence. 

My neighbor has more people living at his house so why is his bill lower than mine?

Sewer bills for single family residences are based partially on water usage in the winter.  If your bill is much higher, you may want to investigate a potential leak by contacting a plumber or your water supplier or consider implementing water conservation measures. 

Why is my bill higher at my new home than my previous home in Chula Vista?

 New sewer accounts for single family homes are set up with a default water usage until a winter water usage is established, please see our sewer policies for more information.  If you have an established water usage, you may be using more water, please consider implementing water conservation measures. 

Why does my sewer bill keep going up each month?

For single family residences, new sewer usages and rates go into effect July 1 of each year and remain the same for the year.  Please see "Understand my sewer bill" if you are not a singled family residence.
