The story

David Mertens, who lives in a single-person household but hosts his children every other weekend, has created a home designed for maximum water efficiency and sustainability. By combining multiple water-saving technologies, he demonstrates how smart design can dramatically reduce household water use.

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

How it came to be

Designed with tomorrow in mind.

The solution.
David installed a Hydraloop H300, which treats greywater from showers and baths for reuse in toilets, laundry, and garden irrigation. Rainwater is collected and purified for showering, while drinking tap water is reserved for kitchen use, handwashing, and brushing teeth, averaging just 13 liters per person per day.

The result.
This integrated system significantly reduces water consumption and prepares the household for rising water costs. David explains:

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

With just a single Hydraloop H300, David's home demonstrates that even small households can achieve substantial water savings, sustainability, and resilience for the future.

How it works in this home

1

Greywater is collected automatically

Water from showers and the bath flows directly into the unit — no extra effort, no change to daily routine.

2

Cleaned on-site, without chemicals

The patented aerobic bioreactor removes bacteria and impurities to NSF/ANSI 350R standard. No filters to replace, no chemicals added.

3

Reused for toilets and laundry

Treated water is automatically routed back for toilet flushing and the washing machine — saving up to 45% of fresh water, every day.

H300

Compact residential unit — designed for homes, apartments, and smaller builds.
