Plumbers, contractors, and industry leaders met with Gov. Healey and top lawmakers last week to lobby for water conservation, worker safety, and good-paying jobs at the annual Plumbing Industry Day at the State House.

Members of Plumbers & Gasfitters Local 12, the Greater Boston Plumbing Contractors Association, the International Association of Plumbing and Mechanical Officials (IAPMO), Plumbing, Heating, Cooling Contractors of Massachusetts, several Massachusetts regional plumbing & plumbing inspector associations, and other industry advocates met with lawmakers at the State House to discuss pending and potential legislation.

A key objective, they said, is safer and more efficient reuse of greywater-wastewater from sinks, showers, and laundries that can be treated and repurposed to conserve water.

“Greywater is the future of water preservation,” said Jim Vaughan, business manager for Dorchester’s Plumbers & Gasfitters Local 12. “ Residential, new builds, every house should have a greywater system ... Think of the relief on the aqueducts, the wells, the public water supply if water was collected and just used for flushing toilets and irrigation.”

Several lawmakers joined the governor in stopping by to meet with the plumbing groups, while plumbers, inspectors, contractors and other industry professionals went door-to-door to advocate for a variety of issues with lawmakers.

The plumbing industry, including manufacturing, wholesale and retail, supports more than 4,600 jobs and is said to have an economic impact of some $760 million in Massachusetts.
