Hydraloop water recycle systems meet EN 16941-2: Why it matters and how it enables a sustainable water future

At Hydraloop, smart water use starts with trust, safety, and innovation. We’re proud to share that our decentralized water recycling systems are fully compliant with the European standard EN 16941-2:2021 for greywater reuse. This compliance is not only a mark of safety and reliability — it’s a gateway to scaling water sustainability across homes, buildings, and communities.

What is EN 16941-2?

EN 16941-2:2021 is the European standard that outlines how to design, install, and maintain systems that treat and reuse greywater for non-potable uses. Published in 2021, it provides essential guidance for systems that recycle water from baths, showers, washing machines, and HVAC condensation for toilet flushing, laundry, garden irrigation and general cleaning. It excludes drinking water, food preparation, hygiene, or industrial and energy-related reuse.

Core functional elements

The standard defines four main components of a compliant greywater system:

• Collection – Greywater must be collected via dedicated pipework to prevent contamination.
• Treatment – Systems must apply appropriate treatment such as filtration, biological processing, or UV disinfection.
• Storage – Recycled water must be stored in opaque, sealed tanks.
• Distribution – Treated water should be safely delivered to its end use without cross-connection with potable supplies.

Hydraloop’s alignment with the standard

Hydraloop’s patented systems meet and exceed the requirements of EN 16941-2:

• Closed-loop systems that collect, treat, and distribute greywater safely.
• Smart treatment technologies without membranes or chemicals.
• Light-proof tanks to preserve water quality.
• IoT-enabled monitoring and safe delivery of recycled water.
• Built-in safeguards, including overflow controls and backup potable supply.

Why EN 16941-2 compliance matters
