Water Filtration & Treatment

Boston Water Group was founded under the belief that a future where everyone can trust their water is fundamentally healthier than one where they can’t.

  • pH correction and ultraviolet disinfection sized to your flow
  • Pressure tank and well pump troubleshooting

Whole Home Water Solutions

Softer showers, spot-free glassware, appliances that last longer, and water at the kitchen tap you would happily give a child.

  • Carbon filtration for chlorine, chloramine, taste and smell
  • PFAS reduction media where the readings call for it
  • Sized to the house, not to a catalogue

Water Softeners

The end of scale on the kettle, film on the shower door and a water heater working harder every year to do the same job.

  • Hardness measured first, then a resin bed sized to it
  • Metered regeneration — salt used on demand, not on a clock
  • Scale kept out of the heater, the dishwasher and the boiler

Drinking Water Systems

One tap in the kitchen you never have to think about — and the end of carrying cases of bottled water in from the car.

  • Reverse osmosis for PFAS, arsenic, nitrate and lead
  • Remineralisation so the water still tastes like water
  • Filter changes tracked and carried out for you

What we do

Water you can trust, wherever it is used

Why us

Built on a belief

Local, intimate knowledge

Eighty-five towns read, mapped and kept current. Your water already has a history, and we have taken the trouble to learn it.

Numbers led, results driven

A lab test first, with every limit printed beside every reading. Trust is built on figures, not on a sales visit.

Installation, done right

In Massachusetts this is plumbing work. A licensed plumber does it, and the paperwork is ours to carry, not yours.

Service on your terms

Twice a year or once every other — you set the pace. The people who install are the people who service.

Strengthening community knowledge

Democratizing water quality data. Every test anonymized and shared so your neighbors have a head start.
