Welcome to the Water Filtration Facility

The water supplying the St. Helens filtration plant is taken from groundwater wells located along the west bank of the Columbia River. These wells are called Ranney Collectors.

The water filtration plant is designed to produce 6 million gallons of water per day. There are 5 “racks” of microfiltration modules. 4 of the racks have 52 modules. Each module has a flow rate of 27 gallons per minute, and an entire rack of 52 modules can produce 2 million gallons of clean, fresh, filtered drinking water per day!

Continuous, fresh, reliable, high quality, filtered drinking water is delivered to your tap, ready to serve you 24 hours a day, 365 days a year.
