Our Mission

At Coastal Water Treatment, our mission is to provide our customers with the best possible water filtration solutions.

One of our favorite phrases is “Follow the Science.”

Water treatment is all about understanding the chemistry of water and what the actual needs of the client are, according to the water test results.

Coastal Water Treatment builds YOUR system for YOUR needs based on YOUR water; we are not a one size fits all company.

That’s the number of water bottles saved from our oceans by installing well water purification systems here in Maine.

Thank you for being a part of the solution!
