Cape Town man Gavin Thompson has initiated a internet challenge which he hopes will make waves in the Mother City.
Thompson took to Facebook to post a video of him re-using grey water from a shower bucket in the toilet cistern to flush with.
The video has had over 1 000 views in the less than 18 hours after posting.
He says his red bucket has become an integral part of his family routine.
Thompson challenged a few people, including Cape Town Mayor Patricia De Lille, to do the same.
He says people simply need to upload their video to Twitter or Facebook and challenge family, friends and businesses to the #capetownshowerbucketchallenge.
Several locals have already come on board, uploading images of their shower buckets as seen below:
