In 2026, Lester Water proudly marks 75 years of serving our community as a third generation, locally owned family business. Founded in 1951, our company was built on a simple promise: provide clean, healthy water backed by honest service and long-term relationships. 75 years later, that promise still guides everything we do.
Lester Water began during a post-war era when water softeners were becoming essential in homes and businesses. From the start, the focus wasn’t just on products, it was on people. That commitment to personal service and reliability allowed the company to grow through referrals, trust, and strong community ties, generation after generation.
A Legacy Built on Service For 75 years, Lester Water has remained a referral-based business because satisfied customers are the foundation of our success. We believe dedicated, transparent service matters just as much today as it did in 1951. Every recommendation we make is rooted in listening carefully, explaining options clearly, and delivering solutions that truly meet our customers’ needs.
Our experienced technicians are known for being prompt, professional, neat, and courteous. When you call Lester Water, you’ll always reach a real person—never an automated system—and you can count on 24-hour emergency service, seven days a week.
Clean Water Solutions You Can Trust Lester Water provides comprehensive water services including accurate water testing and analysis, customized treatment system design and installation, and ongoing maintenance to ensure your water supply is safe, healthy, and reliable. Our approach combines proven technology with hands-on service and decades of experience.
Rooted in Community. Then, Now, and Always Being part of the community means giving back. Throughout our 75-year history, Lester Water has proudly supported local organizations, initiatives, and programs that strengthen the region we serve. We believe that longevity comes with responsibility and that success should benefit more than just our business.
Looking Ahead As we celebrate this milestone year, we do so with gratitude; for the customers who have trusted us, the community that has supported us, and the opportunity to continue serving future generations. Lester Water remains committed to growing responsibly, supporting our community, and delivering clean, healthy water for many years to come.
