West Lake Tahoe Regional Water Treatment Plant

Project Overview

The new West Lake Tahoe Regional Water Treatment Plant will provide a steady and reliable source of drinking water from Lake Tahoe. It will be the main water supply for the McKinney-Quail water system. It also will have the capacity to serve other communities along Lake Tahoe’s west shore. This project will create a more connected water system for both drinking water and fire protection.

The TCPUD Board invested more than $30 million in this project. This represents one of the biggest investments ever made to improve and protect the west shore’s water supply.

The project included:

Construction of the treatment plant and removal of temporary treatment facilities.
Installation of submersible pumps and replacement of water intake pipes in Lake Tahoe.
Building a new pump station at the lake.
Installing new waterlines from Lake Tahoe to the treatment plant and replacement of existing lines.

We look forward to celebrating the grand opening with the community in 2025!
