After more than 20 years revolutionizing the recreational water industry with our low-maintenance water level controls and supremely accurate liquid level sensors and level switches, Waterline Controls is now applying its design knowledge, manufacturing experience and customer service expertise to the electronic level switch for commercial and industrial applications where water level management is critical. Bill Seneff, our President, CEO and Founder is the driving force behind Waterline Controls for the past nine years. Bill started working on the product development for Waterline Controls in 2008 after finishing his twenty year career in the recreational water industry where he sold his previous commercialized product developments during a manufacturing consolidation in that marketplace.
