Sustainable water and wastewater solutions to better, healthier living.

Our mission

The availability of clean, quality drinking water is a basic human right, yet, much of the world still suffers from a serious lack of potable water. In many places, untreated wastewater leads to disease and reduced quality of life, while also wasting precious natural resources. Owini takes on these challenges.


Whether in urban areas or the most remote settlements, by identifying available resources Owini experts strive to ensure a reliable, sustainable water supply for households and farms, while treating wastewater to preserve the environment for generations to come. Our focus in all our endeavors is on people.
