Wastewater Rate Changes

On August 9, 2021, the Palo Alto City Council held a Public Hearing regarding wastewater collection rates.

The Palo Alto City Council approved an increase to wastewater utility rates by 3% on average to pay for rising wastewater infrastructure costs.  Costs are increasing to replace and maintain pipes that transport wastewater (sewage) as well as facilities that treat wastewater. The Regional Water Quality Control Plant (RWQCP) is the wastewater treatment plant owned and operated by the City of Palo Alto that serves Palo Alto and several surrounding communities. Rehabilitation and replacement of plant equipment at the RWQCP that has been in use for over 40 years is necessary to ensure the city can provide wastewater treatment operation safely and in compliance with regulatory requirements for the discharge of treated wastewater 24 hours a day. Wastewater rates are also being updated to maintain cost-based rates and for this reason customers in each customer class will experience different rate impacts. Learn more about wastewater rate changes in Staff Report 12378. The City has mailed a notice letter(PDF, 222KB) regarding wastewater rate changes to all Palo Alto customers on June 16, 2021.

Utility Resources Supply Information

The mission of the City of Palo Alto Utilities (CPAU) is to provide safe, reliable, environmentally friendly and cost-effective utility services. Read more below about these services.  


Effective January 2013, Palo Alto achieved an "all green" carbon neutral electric supply portfolio. Palo Alto gets its electricity from several sources. The exact numbers from each source vary annually.


 The City uses a "market-based" purchase strategy(PDF, 402KB). This means that gas rates change every month based on market prices.  The City of Palo Alto adopted a carbon neutral gas portfolio in 2017. Click here to learn more


Palo Alto is fortunate to get its water from the Hetch-Hetchy system, one of the most pristine, high-quality sources in the country. Like all Californians, we face the risk of not having enough water to meet ever-growing needs in some years; a challenge that is not going away. Recurring drought cycles are a permanent feature of water supply in this state. Learn more about our water supply through our Urban Water Management Plan and Water Resources websites.


Infrastructure Projects


CPAU is always performing ongoing maintenance on its equipment. Several infrastructure projects to replace aging lower voltage lines are ongoing. The new, higher voltage lines will better serve Palo Alto's growing electric needs. 


CPAU leads the industry with an aggressive capital improvement and maintenance program, continuing our work to upgrade, replace and improve the gas distribution infrastructure to reliability and safety. 


Palo Alto's water supplier, the San Francisco Public Utilities Commission (SFPUC) is in the process of completing the Water System Improvement Program (WSIP), a $4.8 billion dollar infrastructure improvement program to seismically retrofit the facilities that transport water to the Bay Area. Debt service costs to fund WSIP infrastructure upgrades will continue to increase over the next few years and will be paid off over approximately 30 years. Parts of the SFPUC’s system not included in the WSIP will also need rehabilitation after the WSIP is completed.

  • CPAU continues a proactive program to upgrade its own water distribution pipelines as well. The City is undergoing a multi-year project to rehabilitate, replace and install new reservoirs and wells. These efforts will bolster our local emergency water supply system. 
  • Both the SFPUC and CPAU projects are investments in the long-term viability of our superior water supply. 


CPAU continues to maintain and replace sewer lines that are reaching the end of useful life. Since July 2011, the City has engaged in an industry-leading program to search for and identify any gas line crossbores into sewer pipes. This program will help ensure customer safety when dealing with blocked sewer lines. One of the main drivers for the increase in the Wastewater Collection Utility’s costs (and therefore rates) over the next several years is the cost for wastewater treatment as the City makes several upgrades to the Regional Water Quality Control Plant. Future projects include secondary treatment upgrades as well as replacement of the headworks facility.
