LETTS Systems
Expert Installation & Maintenance for LETTS Systems
In certain parts of South Carolina, traditional gravity-fed septic systems aren’t an option due to soil conditions, lot size, or elevation. That’s where LETTS systems—Low-Pressure Pipe (LPP) systems—come in. At WeCo Septic & Excavation, we provide professional installation, troubleshooting, and maintenance for LETTS systems to ensure reliable wastewater management.
What is a LETTS System?
A LETTS system uses small-diameter pipes under low pressure to evenly distribute treated wastewater across a drain field. Pumps push effluent from the septic tank into the distribution network, making LETTS systems ideal for:
- Properties with shallow soils or high water tables
- Lots with challenging terrain or limited space
- Areas where a conventional system would not be approved
