A septic tank is a closed storage system used to safely collect and store domestic or industrial wastewater in areas without sewage infrastructure, and to perform preliminary sedimentation before the wastewater is transferred to a treatment system.
Septic tanks manufactured from high-strength polyethylene (PE) material prevent wastewater leakage into the environment thanks to their leak-proof structure and can be used for many years without requiring maintenance.

UNDERGROUND SEPTIC TANK INSTALLATION INSTRUCTIONS
Before placing underground tanks below ground level:
- A reinforced concrete base supported with rebar must be poured at the installation site.
- The concrete must be fully cured before placing the tank.
- After curing, spread 20–30 cm of fine, clean sand on top of the concrete where the tank will sit.
- Using a crane, lower the tank smoothly into the pit without rubbing against the sides, ensuring proper alignment with inlet and outlet connections.
- The distance between the tank and the pit walls must be equal on all sides.
- Level the tank using a spirit level.
- After positioning and leveling, backfill gradually with construction sand.
- Simultaneously with sand backfilling, fill the inside of the tank with water.
- Do not backfill around the tank with soil.
- Ensure that no pedestrians or vehicles pass over the tank.
- Position the tank away from tree trunks and water channels.
- Consider and take precautions against any potential underground pressure or loads that may act on the tank.
