Sewer Project
Rebuilding for our future
The Paradise Sewer Project
In January 2025, the Town of Paradise decided to reevaluate a local wastewater treatment solution rather than export the Town’s
wastewater to the Chico Water Pollution Control Plant. The Town,
with support of the Water Board, is currently analyzing alternatives
for the collection, local treatment, and discharge of Paradise’s wastewater.
A revised project description is expected to be adopted in summer 2025. Learn more about the Sewer Project through this website.
Project Benefits
Provide wastewater disposal surety to help businesses and jobs return to Paradise and spur on recovery.
Allow for more densely-populated residential development in the Town to help increase affordable housing.
Improve Paradise groundwater quality by decreasing septic tank discharges.
Create a wastewater solution supported by the Central Valley Regional Water Quality Control Town Council

Proposed Project
Since its incorporation in 1979, the Town has sought a wastewater treatment solution, with a focus primarily on commercial and densely-populated residential areas — the portions of Paradise most vulnerable to groundwater degradation and economic stagnation due to sewer limitations. To learn more about the history of the Town, check out our Frequently Asked Questions.
In 2020, the Town contracted with HDR, an engineering consulting firm, to prepare an updated assessment of project options. The assessment compared alternatives for local wastewater treatment and discharge with a regional alternative involving piping wastewater to the Chico Water Pollution Control Plant (WPCP). At that time, the regional alternative was recommended with support from the Central Valley Regional Water Quality Control Board (CVRWQCB). The Town Council approved and certified a Programmatic EIR in November 2022. In June 2023, the Town contracted with HDR to act as Owner Advisor and provide broad support for the Project. In March 2024, the Town contracted with the Mountain Cascade – Carollo team to design and build the Project.
In late 2024, detailed project cost estimates made clear that the regional alternative was not economically feasible. As of 2025, the Town, with support from the CVRWQB, is investigating options to build a local, scalable, and economically viable wastewater treatment facility to receive and treat the wastewater from the Town.
Core Collection System
Infrastructure and pipes to collect wastewater from the sewer service area and convey it to the future Paradise Wastewater Treatment Facility.
Wastewater Treatment Facility
A Wastewater Treatment Facility will receive, treat and discharge wastewater from the Town.
Extended Collection System
An extension of the Core Collection System will allow collection of sewage from parcels outside of the Core Collection System but within Paradise town limits up to the allowed capacity.
