Sewer Project

Rebuilding for our future

The Paradise Sewer Project

In 2022, the Town of Paradise approved a certified Programmatic Environmental Impact Report which brought the Paradise Sewer Project closer than ever to construction. In March of 2024, the next major milestone was reached – the Town procured Mountain Cascade – Carollo to design and build the Sewer Project. Learn more about the Sewer Project through this website.

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

Core Collection System

A series of gravity sewers, small pump stations, and pressure pipelines will collect wastewater from the sewer service area and convey it to the future Paradise Wastewater Treatment Facility.

waste water facility

Wastewater Treatment Facility

A Wastewater Treatment Facility will receive, treat and discharge wastewater from the Town.

Extended Collection System

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.
