🧪

Three-chamber digestion

Three staged chambers break down waste step by step before treated water leaves the tank.

🌬️

Open air vent

The 4-inch Tee inlet doubles as a vent, keeping the system odour-free and balanced.

🔧

5-step installation

Inlet and vent, three dummy ports capped, and one outlet. Illustrated guide included.

📐

Compact footprint

The 3500-litre unit measures just 8 × 4 × 4 ft on a 4-inch PCC base.

🌱

Eco-friendly

On-site treatment reduces pollution and needs no sewer line.

How it works

Waste in. Clean water out.

Wastewater flows through three chambers in sequence. Each stage settles and digests solids further.

1

Settling

Heavy solids settle

2

Digestion

Bacteria break down waste

3

Clarifying & outlet

Treated water to drain
