David’s 15 liter family home

David Mertens, who lives in a single-person household but has his children with him every other weekend, showcases the significant impact of integrating multiple water-saving technologies. He uses a Hydraloop H300 device to maximize his water savings by collecting and purifying rainwater for showering. The Hydraloop H300 then treats the used shower water (greywater), allowing it to be reused for toilet flushing, laundry, and garden irrigation. David and his children only use drinking tap water in the kitchen sink, dishwasher, and bathroom sink for brushing teeth and washing hands, using a measured 13 liters per person per day. Through this innovative system, David demonstrates how combining different water-saving technologies can lead to substantial reductions in water usage.

Water becomes scarcer and therefore more expensive. I wanted my home to be future proof to be ready for the increasing cost of water.
