The Submersible Wastewater Pump Association (SWPA) is a national trade association representing and serving the manufacturers of submersible pumps for municipal and industrial wastewater applications. Founded in 1976, the association's primary focus is on industry guidelines, education and promotion.

SWPA's members are leaders in the field. Regular Members are manufacturers of submersible wastewater pumps for municipal and industrial applications that can efficiently handle solids. These companies represent the bulk of U. S. shipments of Non-Clog and Grinder Pumps. Associate Members are manufacturers of component parts and accessory products for submersible pumps and pumping systems. They supply pump manufacturers and the aftermarket with access covers, alternators, basins, cords/cables, control components, control panels, electric motors, guide rail systems, phase converters, phase monitors, seals, valves, variable frequent drives and other components and parts.

SWPA is the industry's leader in providing accurate, up-to-date technical information about submersible wastewater pumps and the component parts and accessories in lift stations using solids-handling pump systems.  Now in its third decade of service, SWPA has become the recognized spokesman for the submersible pump segment of wastewater industry and looks proudly upon its long legacy of service.  SWPA's dedicated members and staff have worked diligently, particularly in recent years, to position the association as the premier resource for technical information on submersible sewage lift station systems in North America.
