Construction to begin on Water Treatment Plant in Lewiston

The city of Lewiston, Idaho, has broken ground on a new water treatment facility. The present 97-year-old Water Treatment Plant was built in 1924 when Lewiston had a population of fewer than 9,000 people. The improved plant’s design and construction method, known as Progressive Design Build, is unique. Throughout the process, the City of Lewiston, Stantec, the design company, and IMCO, the contractor, will collaborate. The project has a budget of $25 million and is expected to be completed in the spring of 2023.

“The water treatment plant is a big capital project that the city has been planning for many years. Just a huge thank you to those who constructed it over a century ago and those who have kept it running ever since. We’re all aware of the cost. What the city is able to afford. We’re already working with the construction contractor during the design process, which is unusual. We’re constantly looking for methods to keep the water treatment plant as inexpensive as possible, so we’ll be utilizing some old facilities that are still in use “Dustin Johnson, Director of Public Works for the City of Lewiston, said

A membrane treatment facility will be built that will be capable of processing 10 million gallons of water per day, with the capacity to increase to 16.7 million gallons. The facility will treat Clearwater River surface water more effectively and to a better standard than the existing plant could possibly achieve. The challenges of this project include finding out how to make the most of the plant’s tiny allowed space, integrating new facilities with those that don’t need to be dismantled, and ensuring that everyone in the city has access to water throughout development. As the irrigation season begins, a temporary system will be installed at the treatment facility to handle river surface water as the irrigation season begins.
