I'm told I have a STEP or STEG system or an E-1 Grinder Pump on my property, what does that mean?

A STEP system is a Septic Tank Effluent Pump system, and a STEG system is a Septic Tank Effluent Gravity system. These systems hold the solid waste and transport the liquid waste from your house to our mainline using a pump (STEP) or by gravity flow (STEG).  An E-1 Grinder Pump sends all waste from the building to the public sewer.
