The NH Tap story.

A Journey from Granite State Roots to Clear Water Solutions.

At NH Tap, our journey is deeply rooted in the Granite State’s charm and the determination of a native son, Keith McDonald, to tackle the pressing water challenges of New Hampshire.

Keith’s story begins in the picturesque town of Jaffrey, where he spent a quintessentially New Hampshire childhood, filled with the same dreams and aspirations as many other kids in the state. His adventurous spirit took him far from the familiar landscapes of New Hampshire, all the way to Orlando, where he pursued an exciting career in professional break dancing. However, it was in Florida, known for its water woes, that Keith’s path took a pivotal turn. His exposure to the state’s water issues, ranked among the most severe in the nation, ignited a passion for water treatment and conservation.

Diving deep into the study of public water systems, aging infrastructure, and the daunting challenges posed by industrial pollution, Keith recognized a pressing need. He envisioned a water filtration system that wasn’t just effective but could genuinely enhance the health and wellbeing of individuals.

Returning to New Hampshire in his early 30s, Keith saw his home state grappling with its own set of water issues. Despite being surrounded by natural beauty, New Hampshire’s public water systems were battling the strains of a 125-year-old distribution network, alongside issues like chemical runoff and natural heavy metal presence. Surprisingly, despite the gravity of these issues, little progress was being made to address them effectively.

With a wealth of field experience under his belt and a self-taught expertise in chemistry, Keith set about engineering a solution. He developed a comprehensive whole-house water purification system, specifically designed to tackle the unique challenges of New Hampshire’s water. This system effectively removes metals and chemicals, ensuring that the water in New Hampshire homes is as clean and healthy as the picturesque landscapes of the state.

Thus, NH Tap was born—not just as a business, but as a commitment to the health and wellbeing of New Hampshire residents. Keith’s journey from a young boy in Jaffrey to a water treatment expert embodies his dedication to his roots and his unwavering passion for providing his fellow Granite Staters with the best possible water. At NH Tap, we’re more than a company; we’re a part of the community, striving each day to make New Hampshire’s water as pure and refreshing as the state itself.
