Sewer Service Charge

Sewer Service Charge (SSC)


The Sewer Service Charge (SSC) is applied to metered water use to obtain money for constructing and maintaining sewers and sewage treatment plants, and for treating sewage which is discharged into the sewer system. The officially adopted ordinances, rules, and regulations will rule in case of any conflicts. Refer to Los Angeles Municipal Code (LAMC) Section 64.41, as modified or to the actual LAMC code citing.

This fee is on your Department of Water and Power (DWP) bill, if you are currently billed for the service. The charge is based on metered water use and generates funds for constructing and maintaining wastewater facilities such as sewers and sewage treatment plants, and for treating the sewage that is discharged into the sewer system.

The current SSC rate is​ $4.80 per 748 gallons or one HCF (hundred cubic feet) of sewage volume​.

For this fiscal year, the DWCF is 0.98 and the Rainy Season Review Period (RSRP) was from October 17, 2016 to April 8, 2017.

The low income surcharge (LIS) is 0.00572 of your SSC amount.

For commercial customers, the default percentage discharge is 93%.


Residential Sewer Service Charge (SSC)


Your residential Sewer Service Charge (SSC) is based on the amount of water you use. The residential SSC is calculated this way because most of that water eventually goes down the drain and into the sewer system.

Winter Water Use (WWU)


To calculate the residential SSC a methodology called the Winter Water Use (WWU) is used.

The WWU contains a number of mathematical concepts which are used to bring your SSC charges more in line with your actual use of the waste water system.

1. On July 1 of each year we calculate your average daily winter water use (WWU). We take the billing period of the previous winter that had the lowest daily water consumption and divide that consumption by the number of days within that billing period. This daily average is shown in hundreds of cubic feet per day or HCF/day (1 HCF = 748 gallons).

WWU = HCF Per Day / Days in Winter Lowest Daily Water Consumption Billing Period

2. To account for winter irrigation, we usually reduce the WWU by using a Dry Winter Compensation Factor (DWCF) in the calculation. This year’s DWCF is 0.98. 

3. When we apply the DWCF we get your Average Daily Sewage Volume (ADSV). Once we’ve determined your ADSV, for billing purposes we say that your sewage flow remains the same from July 1 to June 30.

ADSV = DWCF x WWU

4. Now we are able to calculate your bi-monthly SSC. We multiply your ADSV by the SSC Rate (currently, $4.80 per HCF) and the number of days in the current billing period.

Sewer Service Charge = ADSV x SSC Rate x Days in Current Billing Period


In September of each year you receive a Sewer Service Charge information pamphlet. We suggest that you keep it handy. It contains helpful information such as how to lower your water bill, how you may qualify for a refund, how to protect your sewer, wastewater system and much more.

Sub-meter Customers


If you have a water sub-meter, the water you use and discharge into the sewer system will be measured and billed as follows:
SSC = SSC rate x Volume of Domestic Water Used for the Billing Period (in HCF)
Water sub-meters may often be beneficial for properties that cannot significantly reduce irrigation (for example, large lots).

Pursuant to Los Angeles Municipal Code (LAMC) Section 64.41.03(g)(3) (A)(ii), after installation of a sub-meter, subsequent billings will be calculated based on actual internal water consumption.

Before you install a water sub-meter, please call (800) 773-2489 or (213) 473-4181 to request a residential or commercial water sub-meter information package.
