WTP CONSTRUCTION UPDATE

Construction of a new membrane filtration Water Treatment Plant for the City of Lewiston is underway. While upgrades are being done, the City’s system is pulling 100% of its water from six groundwater wells, and this means residents may notice a change...

...in the hardness and/or temperature of their water. It’s important to know that these aesthetic changes are normal and occur naturally. In fact, changes in water sources happen seasonally as the City uses and blends water from seven different sources. These changes will just be more significant during construction.
