Corrosion Control 101

Corrosion Control in Water

You might be surprised to learn that water is a naturally corrosive product.  As part of Aquarion's water treatment process:

  • we test the water and adjust for pH and treat for corrosion control as indicated;
  • we also add a phosphate-based corrosion inhibitor - which means our water is lead-free as it leaves our treatment facilities.

In addition to ensuring our water remains lead-free all the way through our water mains, our treatment also helps to coat the pipes and fixtures in your home.

While the corrosion inhibitor helps to reduce the amount of lead that may leach from lead materials in your plumbing system, these steps may not be 100% effective in all cases: if you live in a house built before 1988, we urge you to have an independent testing lab check the water coming out of your taps to see if lead is present.

Here is a link to laboratories certified by the State of Connecticut to test for lead in drinking water:
