BIRMINGHAM, Ala. (May 5, 2014) – Pumps & Systems, the leading magazine for pump users worldwide, is happy to announce “Grinder Pumps in Pressure Sewer Systems,” a webinar presented in partnership with the Submersible Wastewater Pump Association (SWPA), the educational leader and authoritative source for the submersible wastewater pump industry for more than three decades.

The live webinar will take place June 19, 2014, at 1 p.m. Eastern. Register for free at

In “Grinder Pumps in Pressure Sewer Systems,” Clark Henry, director of engineering at Environment One Corporation, and Walt Erndt, vice president and general manager of the Municipal Group at CRANE Pumps & Systems, present fundamentals with an emphasis on the design, construction, installation, operation and maintenance of a system of carefully integrated components. Grinder pump stations contain several complex, interdependent components that must be properly matched to each other to ensure a long and economical life.

In this webinar, typical system component drawings will be presented—an elevation view and an aerial view—along with many of the terms commonly used in connection with grinder pumps and pressure sewer systems.
The one-hour event will include a 45-minute presentation followed by a 15-minute live question-and-answer segment.
