Zero sludge — by design
The biofilm converts. Nothing is wasted.
In a conventional STP, organic matter settles as sludge — collected, dewatered, and hauled away at your cost every month. Biopipe's biofilm mineralises organics completely: CO₂ and water are the only outputs.

Biopipe replaces aerators, clarifiers, and sludge pits with a single tuned ecosystem of bacteria living on the inner wall of a vertical pipe. Water flows in; clean water flows out.
Because the biology does the work, the machine gets smaller — fitting under podiums, inside utility rooms, and on rooftops where conventional STPs can't go.

Why Biopipe?Everything conventional STPs
Everything conventional STPs
get wrong, we fixed.
Sewage treatment doesn't have to be dirty, expensive, or complicated. Here's how Biopipe is different — in plain language.
🚫
Zero sludge. Forever.
Conventional treatment plants produce tonnes of sludge every day — that costs money to remove, treat, and dump. Biopipe produces none. The biology inside the pipes converts everything into CO₂ and water. That's it.

🧪
No chemicals needed.
Most STPs add chlorine, coagulants, and defoamers constantly. Biopipe uses living bacteria on the inside of vertical pipes — they do the work naturally. No chemical costs. No hazardous storage. No smell.
Zerochemical dosing
⚡
70% less electricity.
Aerators and blowers in conventional plants run 24/7 and devour electricity. Biopipe's biofilm breathes on its own — just one small pump circulates water. Your electricity bill drops from day one.

Fits in a car park.
A 500-person apartment complex needs a treatment system that fits in 1/6th the space of a conventional plant. Biopipe goes under a car ramp, inside a utility room, or on a terrace — invisible to residents.

Frequently asked questions
Biopipe, answered.
What is Biopipe and how does it treat sewage?+
Biopipe is a decentralised, sludge-free sewage treatment system that uses living biofilm bacteria growing inside a network of pipes to break down waste water naturally. It replaces the entire conventional STP — aerators, clarifiers, sludge pits and chemical dosing — so treatment happens quietly, on-site, with no moving parts to service.
Does Biopipe produce any sludge or odour?+
No. The biofilm mineralises organic matter completely into carbon dioxide and water, so there is zero sludge to collect, dewater or haul away, and no hydrogen sulphide odour at the site boundary. That means no monthly tanker calls and no sludge-disposal cost.
Is Biopipe-treated water safe to reuse and is it compliant?+
Yes. Treated effluent meets CPCB, CPHEEO, NGT and EU Urban Waste-Water discharge norms with margin to spare, and is reuse-grade — suitable for flushing, gardening, landscaping and cooling towers. Every installation is certified before handover.
How much space and power does a Biopipe system need?+
Biopipe is modular and compact — a 1 m³/day unit fits in a 4×4 ft utility room — and scales to 700 m³/day. It runs on roughly 0.3 kWh/m³, far less than conventional MBR or SBR plants, needs no daily operator, and can run on solar or gravity at off-grid sites.
Where can Biopipe be installed?+
Across residential, commercial, hospitality, healthcare, institutional and industrial sites — installed in 15+ countries and backed by 55+ patents. The same core biology can operate in climates from −20°C sub-zero alpine to +45°C desert heat.
