Do you support the Chico sewer rate increase despite the large monthly hike?
The Chico City Council approved a sewer rate increase in June that raises monthly payments by more than 160% over five years. City officials say years of stagnant rates left the city needing to catch up on rising infrastructure costs.
Why it matters
State regulations requiring a 10-acre holding pond are among the biggest drivers of the increase, which affects Chico residents and property owners directly. Pushback from the business community and property owners has continued.
Monthly sewer payments are set to rise more than 160% over five years, with a required 10-acre pond estimated near $30 million and a nitrate removal upgrade above $9 million. Many facility components were built 27 years ago, and the final allocation of these costs remains under public review.
The players
Chico City Council
The elected governing body of Chico, California, responsible for approving municipal utility rates and budgets for city services.
City of Chico
The municipal government of Chico, California, which operates the Chico Water Pollution Control Plant and oversees sewer service for residents and businesses.
The details
The increase is tied to new state regulations requiring the city to build a pond to hold non-compliant water so it is not discharged in violation of the NPDES permit. The rate hike could also fund expansion of departments at the Chico Water Pollution Control Plant, including the administration building that houses the water quality lab.
Timeline
June: Chico City Council approves the sewer rate increase.
Nov. 17: Council is scheduled to continue public hearings on sewer rates.
Over the next five years: Monthly sewer payments rise more than 160%.
Market Landscape
The increase reflects a broader pattern in which wastewater utilities must fund costly compliance upgrades under NPDES discharge permits after years of deferred rate adjustments. Chico's situation follows the same trajectory as other California cities facing stricter state discharge standards and aging treatment plants.
Monthly sewer bills in Chico are set to rise more than 160% over five years, directly increasing household and business utility costs. Property owners who wish to formally oppose the increase would need more than 10,000 valid protest submissions to trigger a majority protest.
The takeaway
Residents and property owners who want to weigh in should follow the Nov. 17 public hearings on sewer rates before the next round of charges takes effect.
