Big sewage plants need a sewer line, steady power and trained staff. Many small towns, new colonies and villages have none of these. Their sewage flows down open drains into the nearest lake or river, and the village pond turns green and smelly.
Clean the drain itself
If an open drain (nallah) already carries the sewage, you can clean it inside the drain. Helpful bacteria are added and break down the sewage as it flows. Filter beds and planted areas are built into the drain. No land to buy and no pumps to run.
Planted gravel beds for colonies and villages
Planted gravel beds clean sewage the way nature does. The sewage flows slowly through gravel planted with chosen plants. The roots, and the bacteria on them, clean the water. There is no power bill, no chemicals and no sludge to remove. For salty water near the coast, salt-loving plants do the same job.
Ready-made units for small spaces
- Sewage plant in a box: arrives ready to connect. Good for camps, site offices and small groups of houses.
- Small plant that makes biogas: for food businesses with strong wastewater and little space.
- Home bath water reuse: cleans bath and kitchen water for flushing toilets and watering plants.
Bring the pond back to life
Once the sewage stops flowing in, a dirty pond can recover. A floating cleaning unit breaks down the green algae and adds oxygen. Water hyacinth pulled from the lake can be turned into compost and sold, which pays for removing it.
Clean septic tanks safely
Septic tanks still need emptying. Machines on a vehicle empty the tank and clean drains, so no worker has to go inside.
Need sewage treatment without a sewer line?
We visit the site, test the sewage and design a low-power system. See every option in our technology showcase.
Request a consultationFrequently asked questions
How much land does a planted gravel bed need?
More than a machine-based plant, usually a few square metres for each house it serves. If land is short, choose a ready-made unit or clean the drain itself.
Can the cleaned water be reused?
Yes, for gardens, trees and other uses where people do not drink it, as long as it meets the reuse rules where you are.
Does cleaning sewage inside the drain smell?
It reduces the smell. The helpful bacteria break down the things that make a still drain stink.
