Site Drainer™ inventor and founder, Antonio Perez is familiar with innovative solutions. With a background in manufacturing and distribution, an interest in industrial engineering, and a passion for invention, he has always had a curiousity for figuring out how to solve common problems with simple solutions. Upon speaking to several colleagues in the construction industry, he repeatedly heard how dewatering pumps were contributing to inefficiencies on the job site with their constant clogging. Cumbersome work arounds, such as drilling holes in buckets, were being used to try to avoid clogging. Highly curious, Antonio decided to find out why the pumps clogged and if there was an easier and more reliable solution. In 2009, his idea of the "free flow casing" - the innovation which sets Site Drainer™ apart from all other dewatering pumps - was born.  

Mr. Perez's vision is for Site Drainer™ to become the innovative and superior solution to what is currently lacking in the electric submersible dewatering pump industry.
