WASTEWATER RATE AND CAPACITY CHARGE STUDY

1. INTRODUCTION

The City of San Carlos is seeking Proposals for a Wastewater Rate and Capacity Charge Study.

2. BACKGROUND

San Carlos, incorporated in 1925 as a General Law city, encompasses 5.6 square miles and is

located exactly halfway between San Francisco and San Jose. The City is governed by a five-

member City Council with members selecting a Mayor for a one-year term and has an appointed

City Manager. There has been a great emphasis on public participation in local government and

the citizenry is quite active. Other information regarding the City of San Carlos can be found on the

City’s website – www.cityofsancarlos.org.

The City provides wastewater collection services for its residential population, estimated at around

30,700 people as per 2020 census data, as well as its commercial businesses. The City’s sanitary

sewer system includes approximately 100 miles of gravity sewer mains, ranging from four inches in

diameter to 36 inches, about one mile of pressure mains, and four sewage pump stations.

All sewage collected through the City’s sanitary sewer system is conveyed to the San Carlos Pump

Station located at Monte Vista Drive and Skyway Road. The San Carlos Pump Station is owned

and operated by Silicon Valley Clean Water (“SVCW”), a Joint Powers Authority (JPA) serving the

communities of Belmont, San Carlos, Redwood City, and the West Bay Sanitary District. Sewage

from the San Carlos Pump Station is then pumped to the treatment plant located in Redwood

Shores. Previously, to help fund an expansion of the treatment plant to increase treatment

capacity, each member agency was required to collect and transfer its own connection fee to

SVCW. However, if member agencies build developments in accordance with their respective

general plans (including San Carlos), most will exceed their allocated capacity rights negotiated

with the treatment plant expansion. Further discussions are needed to determine how the

treatment plant will meet projected demand.

In 2016, the City completed a wastewater capacity charge study that updated sewer capacity

charge designed to equitably recover the costs of City sewer system infrastructure and assets

benefiting new development.

In 2019, the City completed a wastewater rate study that updated sewer rates for a four-year

period, and another was completed in 2024 for the next three years.

In 2025, the City completed an update to its Sewer Collection System Master Plan to

comprehensively evaluate the sanitary sewer system capacity and develop a phased capacity

assurance capital improvements plan under existing, near-term, and buildout scenarios,

incorporating current system characterization and projected growth, to guide the City in meeting

sewer service demands presently and into the future. The sewer model of the City’s collection

system developed as part of the 2013 Master Plan was also updated to address minor data gaps

and include all the pipes in the Northeast Area Specific Plan (NEASP) and Downtown Specific Plan

(DTSP) area.

Finally, the City’s Capital Improvement Program (CIP) has a wastewater fund that earmarks $10

million to $12 million annually to support its sewer and wastewater projects, with a majority of the

funding dedicated to the Annual Sewer System Rehabilitation Program.
