Shallow Treatment Tank | 4 Person Marsh Horizontal Septic Tank

Free UK Mainland Delivery Included within 5-10 working days*

The Marsh 2800L Horizontal (Shallow Dig) Septic Tank is a robust, low‑profile domestic sewage solution designed for properties where connection to the mains sewer is not possible. Its horizontal design reduces excavation depth, making it particularly suitable for high water table areas, hard rock ground conditions, or sites where deeper digging is impractical.

Main Benefits
- Pedestrian‑rated cover and frame included as standard
- Ideal for off‑mains sites requiring secure containment of sewage, wastewater, or greywater
- Shallow dig design reduces excavation time and ground disturbance 
- Suitable for difficult ground conditions e.g high water tables or rocky terrains
- Heavy duty GRP shell ensures long service life in all ground conditions
- Lower risk of groundwater issues thanks to its horizontal footprint

Key Features
- Ideal for domestic dwellings with limited occupancy
- 2800ltr capacity serves up to 4 occupants
- Integral lifting eyes for easier, safer on‑site handling
