Our Irrigation Company Team

Sean Mullarkey - Founder of Tri-State Water Works, Cincinnati, Ohio


As the founder and president of TriState Water Works, I have been in the horticultural industry my entire life, designing and servicing irrigation projects for decades. My certifications include: Certified Irrigation Designer, Certified Irrigation Contractor, Certified Landscape Irrigation Auditor, Certified Golf Irrigation Auditor, EPA Water Sense Partner and Certified Landscape Water Manager.

I decided to start my irrigation company while I was working as the territory manager for a major irrigation wholesaler. I saw how contractors were treating their customers by providing poor service. I could not understand how contractors could be hours late for appointments, take days to return phone calls, or have to make several appointments to fix a single problem and call themselves professionals. I want to make a difference; we have a live person answering the phone during  business hours, all phone calls will be returned in one business day, 90% of service calls will be handled on the first visit and we will arrive promptly for our appointments.

Conservation is a primary objective for TriState Water Works. Wasted water is not acceptable. Water is a finite resource; less than one percent of the earth’s water is available for consumption. We are blessed in the Greater Cincinnati area to have an abundance of water while other areas of the world are having a water crisis.
