RECOGNISED BY

Water is the silver drop of life — one with infinite potential to be recycled. At Watwa Engineers, we harness a few of the many ways water can be renewed, so it can be reused again and again.

Our Mission

We divert grey and black water through constructed treatment wetlands, where it passes through a progressive natural purification process — emerging as clean water ready for reuse.
