The output of Hydraloop is odorless, transparent & disinfected of bacteria and virusses, just like tapwater, BUT not potable. Therefore it is very applicable to use for toilets, washing machines, cleaning water, gardens, swimming pools.

Grey water re-use is quite new and therefore, depending on the region or country, legislation is not always prepared yet.

Standard Hydraloop output is allowed to be re-used:

• In Wallonia for: toilets, washing machines, gardens, swimming pools, showers, baths…
• In Flanders for: toilets, washing machines (for now: prohibited to connect to rainwatertank & WADI)
• In France for: toilets, washing machines​
