Questions

Frequently asked questions.

Is this technology proven?

Yes. It is at ready level 9 of 9, which means: already in use. Works for a single home or a whole village.

What does it cost to run?

About 3 to 5 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.
