Phillip Merrill Owner: 22 years of experience in the drinking water and wastewater field

Phillip Merrill grew up helping out in the family water well drilling business. Summers were spent learning the trade from his father. After college, he joined the family business full time. After his father’s retirement Merrill Water Systems branched out into operating and managing community water systems. This was a natural fit as Phillip had a deep understanding and technical expertise in the infrastructure and operation of these systems.

We can do all of the tasks necessary to manage and operate the system. We work with system owners to assist in regulatory compliance assistance and the operation of the drinking water delivery system. We help monitor the quality of the drinking water in order to provide safe clean drinking water.
