2018-2022 Proposed Sewer Rate Increase

**Link to June 28th City Council Meeting Staff Report of Sewer Rate Increases: Click Here


The City is proposing to increase the current base rate which appears on your annual property tax bill as “SSF SEWER CHARGE”, in FY 2017-18 by 15% for all user groups. The City is proposing to raise the commercial and residential sewer service rates over the next five (5) years to pay for increased operating costs and large Capital Improvement Program (CIP) projects. The subsequent proposed annual increases are as follows: 10% in 2018-19, 5% in 2019-20, 5% in 2020-21, and 5% in 2021-22.

Since the last sewer rate plan was approved, staff focused the Capital Improvement Program to fund:

  • A web-based monitoring system to remotely monitor operations;
  • The purchase and installation of additional efficient turbo blowers, which provides energy cost savings; and
  • Point repairs and installation of new liners in existing sewer mains to prevent root intrusion and reduce sewage leakage into the ground.

In the next five-year CIP, staff forecasts approximately $77 million worth of capital improvement projects that will:

  • Provide the replacement of two digesters and retrofit a third which allows the plant to achieve an approximate operational cost savings of $150,000 annually;
  • Complete projects critical to maintaining the City’s National Pollutant Discharge Elimination System (NPDES) permit; and
  • Upgrade and increase reliability during utility power outages though the design and construction of automatic switchgear and cogeneration controls.

In order to complete the proposed capital projects, the City must increase its current rates. The City’s rates are currently low compared with other San Mateo County cities and will continue to be lower than most, even with the proposed rate adjustment for next year. With a proposed 15% increase next year, residents will see an increase of approximately $7 per month in fiscal year 2017-18.

A PUBLIC INFORMATION MEETING is scheduled for May 16, 2017, at 7:00 PM at the Magnolia Recreation Center, Multi-Use Room, 601 Grand Ave. So San Francisco. City staff and project engineers will be available to answer any questions regarding the proposed sewer increases. As this in an informational meeting, the City Council will not be presiding over this meeting and the City will not take any action on the rate increase at this meeting.

The proposed rates will be recommended to the South San Francisco City Council for adoption following a PUBLIC HEARING at the City Council meeting scheduled for June 28, 2017, at 7:00 PM (Municipal Services Building, 33 Arroyo Drive, So. San Francisco). Your written protests must be delivered to the City Clerk by the close of the public hearing in order to be considered.

Any property owner, who receives sewer service from the City or the tenant responsible for payment of the sewer service, may file a written protest against the proposed rate increase with the City Clerk. The protest must include: (1) the property owner name and address, (2) the assessor’s parcel number (APN), and (3) signature of the person submitting the protest. No more than one protest per parcel may be submitted. The written protest may be:
  • Hand delivered or mailed to the City (City Clerk's Office, 400 Grand Avenue, So San Francisco, CA 94080); 
  • Received by mail no later than 4:00 pm on June 28, 2017 (see address above); or 
  • Delivered in person no later than the closing of the public hearing. 
*A majority protest exists if there are valid written protests submitted for a majority of the properties subject to the proposed rate increase by the end of hearing. A majority protest will result in the rate increase not being imposed.
