Years In Business
Our History

Tim Harmsma, owner of 1000 Water Treatment & Plumbing, leads a team committed to delivering honest, reliable service and quality workmanship. Under his guidance, the company continues a legacy built on integrity, dependability, and customer trust.

The roots of the business go back to 1975, when Peter Harmsma—a hardworking Dutch immigrant—established a reputation for doing the job right the first time. Rick Harmsma later carried forward this philosophy, and in 1992 the company officially became 1000 Water Treatment & Plumbing. Today, Tim and his team uphold these same standards, ensuring every project meets the high expectations the community has trusted for decades.

Our reputation is built on lasting relationships, word-of-mouth referrals, and a commitment to honest value and exceptional service—every time.
