About us

Water engineers, not equipment resellers

Commercial building in India served by an Aquatron sewage treatment plant

India Water Systems began with a simple frustration shared by every facility team we met: sewage plants that were built once and then fought with forever — sludge to cart away, blowers running through the night, odour complaints from the floors above and a power bill that never stopped climbing.

Working out of our head office in Hyderabad and serving projects all over India, our engineers spent years commissioning and repairing conventional plants before adopting the Aquatron process — a patented European separation technology with 38+ years of field history and 12,000+ installations worldwide. We have since put 300+ plants into service in India, from high-altitude army posts to hospitals, co-working floors and residential towers.

We handle the whole chain ourselves: sizing, bio-chamber layout, supply, installation, commissioning and long-term service. That is also why our first response to an enquiry is a set of numbers rather than a product pitch — if the flow and the site do not suit the process, we say so.

Our mission

To make clean water treatment something a building can simply live with — quiet, odourless, affordable to run, and reusing every litre it can.

Why Aquatron STP is different

01

Solids never reach the plant

The patented European separator diverts faecal solids at the source using gravity and surface tension. Everything downstream only ever handles liquid.

02

Nothing to break in stage one

No pumps, blowers or chemicals in the separation stage — no moving parts means no breakdown schedule and no operator up to 500 KLD.

03

Costs that fall every year

35% lower CAPEX, 65% less electricity, 80% lower annual OPEX and 60% less built-up space than a conventional plant of the same capacity.

04

Built to outlive the building

A 50-year design life, 38+ years of field history and results that clear NGT and CPCB limits at installed sites across the country.
