What the Spareau Family kit does for you
The Spareau Family kit turns your home into a genuine grey-water recovery station. Installed at the lowest point of the drainage network, it automatically collects unpolluted wastewater, filters it and prepares it for a second use.
Grey-water collection
The Spareau Family kit captures up to 100 % of the water from your wash-basins, showers, baths and washing machine. A dedicated collector diverts this flow to a self-cleaning pre-filter that traps hair, fibres and suspended particles. You recover pre-cleaned water, free of the main residues and ready for treatment.
Grey-water treatment
Once pre-filtered, the water passes through a compact treatment module: activated-carbon adsorption, multi-cartridge fine filtration and UV disinfection. This process effectively removes bacteria, micro-pollutants and soap traces, providing a hygienic quality suitable for non-potable domestic uses.
Grey-water reuse
After treatment, the recycled water can irrigate lawns and vegetable plots, supply toilet cisterns and floor washers, and even wash your car. By connecting a simple secondary distribution network, you can replace up to 40 % of your drinking-water consumption with upgraded grey water.
Save 40 % + on your bills
By reducing drinking-water use by up to 50 %, the Spareau Family kit typically cuts quarterly bills by around 40 %. The investment pays for itself in three to five years (depending on local tariffs) and may qualify for local grants or tax credits for water-saving equipment.
Save 40 % + of drinking water
By intelligently reusing grey water, you preserve tens of cubic metres of drinking water each year. This simple action eases pressure on aquifers, shrinks your household water footprint and actively contributes to tackling water stress and meeting sustainable-development goals.

Who is the Spareau Family kit for?
Designed for any premises accommodating up to six people, the Spareau Family comes as a ready-to-install kit that is simple to put in place. Ideally positioned at the lowest point of the drainage network so it can recover grey water by gravity, it can be paired with a second tank (XL version) to double its capacity, making it suitable for small collectives of up to 12 people (holiday cottages, site cabins, offices, etc.). Cut your drinking-water use by at least 40 % with the Spareau Family!
