Stepros LLC is a family owned and operated manufacturer of pump vaults and filters for the wastewater industry. A veteran of the decentralized wastewater industry, Bob Pickney set out to improve upon the wastewater pump vault and filter packages that were commercially available. After many years of research and development and several prototypes, he created a vault that would filter effluent without collecting solids. This innovation in septic tank effluent filtering was recognized by the U.S. Patent and Trademark Office in August of 2011 by the granting of a patent. (https://patents.google.com/patent/US8002996)
