Problem and fix
The problem this solves.
- 01The problem
The village hand pump gives clear water that tests high for arsenic.
How it is fixedThe plant fits on the hand pump. Water flows through tanks of natural minerals that hold on to arsenic. Once a week, water is run backwards through the tanks (a backwash) to clean them. No power or chemicals needed.
How it works
Step by step.
- 1
Pump
People use the hand pump or submersible pump as usual.
- 2
Filter
Water passes through tanks of natural minerals and manganese oxide that hold on to arsenic.
- 3
Supply
Safe water comes out of the plant's tap.
- 4
Backwash
Once a week, water is run backwards through the tanks to clean them.
Key features
Why it works well.
Brings arsenic below the safe limit of 10 µg/L. Treated water costs 3.5 to 8 paise a litre. Sizes from 350 to 5,000 litres an hour.
- Fits existing pumpsBolts on to a standard hand pump or a submersible pump.
- No power, no chemicalsRuns on the pump's own pressure.
- Long-life mediaThe filter material is cleaned by backwash, so it lasts longer.
- Instant safe waterNo waiting or storage tank needed for treatment.

Questions
Frequently asked questions.
Is this technology proven?
Yes. It is at ready level 6 to 7 of 9, which means: tested in the field. Brings arsenic below the safe limit of 10 µg/L. Treated water costs 3.5 to 8 paise a litre. Sizes from 350 to 5,000 litres an hour.
What does it cost to run?
About 3.5 to 8 paise a litre. The exact figure depends on your water and the size of the plant. We confirm it after testing a sample.
Can we try it on our own water first?
Yes. We test a sample in our NABL-accredited lab and, where it helps, run a small trial on your site before you invest in a full plant.
Do you supply and install it?
Yes. We design, supply, install and start up the system, train your staff, and our lab checks the treated water.
