Clean Water & Sanitation


What is the problem you found?

How might we encourage others to reduce water waste?


Customer / Problem

We are concerned with the large/excessive amount of fresh drinking water that is constantly being used in toilets for flushing waste. This is contributing to the waste of clean water which people in need are desperate for. 

What Is Your Solution?

Our solution to this issue is a water tank which transforms the greywater from a shower or bath from its bacterial state into a cleaner state for toilet use. This reduces the amount of clean water being wasted. This tank will be compulsory for all new houses, as it will be under the house. For previously built houses, this tank will be placed on the side.
