STEP Systems for Effluent Collection

A STEP (Septic Tank Effluent Pump) system is a form of pressure sewer that has several advantages over traditional gravity collection systems:

• The quality of effluent from STEP Units allows the collection system to be designed the same way as a water system. Small diameter PVC pipe is laid in shallow trenches. Infiltration problems are eliminated, and hence, treatment plants can be smaller; lift stations and manholes are not required.
• Per - unit costs can be much lower, especially in areas with dispersed dwellings, hilly terrain, high water table or rock. The on-site costs can be deferred until occupancy.
• STEP effluent quality (average TSS 29, BOD5 129) is much better than sewage, reducing the biological load.
• STEP units encourage responsible water use and disposal practices by the homeowner.
• Maintenance and operating costs are the same as, or less than, conventional sewers.
