Working for Our Customers


About Us

Regional San owns and operates the regional wastewater conveyance system and the Sacramento Regional Wastewater Treatment Plant  located near Elk Grove, California. We serve a population of about 1.4 million in the region.

Our Mission

Regional San protects public health and the environment by conveying, treating, and recovering resources from wastewater responsibly and cost-effectively.


Monthly Rates for Residents

Regional San customers pay a monthly rate for wastewater conveyance and treatment services. Instead of receiving a separate bill, our monthly charge appears on customers’ sewer collection utility bill.


Age-Restricted Residential Development Customer Category

Regional San has a rate and fee category for developments with 21 or more units that are restricted to residents aged 55 years and older. This applies to single-family, multi-family, condos, apartments, and mobile home developments that meet the age restrictions and the required minimum number of age-restricted units. The age-restricted monthly rate is 60 percent of the regular single-family monthly rate. The new rate category became effective July 1, 2016.


Impact Fees

In order to buy into Regional San’s wastewater conveyance and treatment system, builders, developers, and industries pay impact fees to connect. The amount of fees required depends on a number of factors, including location of parcel, use of parcel, and characteristics of  wastewater being discharged. In addition, there are various programs or options available that can affect when and how payments are made for fees. See the Regional San Consolidated Ordinance for detailed information.


Rate Assistance Program

Regional San offers eligible low-income customers a savings of $90 to $150 per year on the conveyance and treatment portion of their sewer bill, depending on the type of dwelling.

To qualify for the rebate, your name must appear on the sewer bill, you must meet certain income criteria, and you must live at the address for which the rebate is being requested. Only one rebate per customer.


Tour the Treatment Plant

Have you ever wondered what happens to the water you use after it goes down the drain?

To find out, join us on a fascinating and educational tour of Sacramento’s regional wastewater treatment plant. Regional San conducts FREE group tours on specific dates (mornings and afternoons) each year. You’ll also learn how the EchoWater Project will help us meet new environmental regulations.

Reservations are required, as space is limited, with preference given to Regional San customers.


Water Efficient Toilet Rebate Program

Did you know that toilets account for more than a quarter of all indoor water use?

Regional San is committed to protecting the environment and educating the public on important water quality issues.

In an effort to help maximize the availability of the region’s precious water supplies, we have entered into an agreement with the Regional Water Authority to provide rebates for replacing high water consumption fixtures with more water efficient fixtures. Water customers may be eligible to receive a rebate up to $175 for installation of a High Efficiency Toilet.
