Sewer Service Charges

Making sense of your bill

An annual Sewer Service Charge (SSC) is placed on your Santa Barbara County property tax statement. The charge appears on the tax statement as a line item listed as CARP SAN DIST SVC CHG. The SSC is not a property tax and is not related to the assessed value of your property. It represents a charge for a service provided, similar to your phone, gas or electric bill. It is included on your property tax statement to save the administrative cost of generating and mailing our own invoices.

All residential customers pay a flat annual charge for sewer service.  Customers in low-pressure sewer service areas pay an annual surcharge to cover proportionally higher costs.  Non-residential customers are charged a variable rate based on the average volume and strength of wastewater discharged annually.
