Water is becoming a precious commodity around the world. Finding ways to conserve it is rapidly becoming a priority. One area that’s seen little attention (until now) is conserving and reusing graywater from baths, showers and toilets.
Reaqua Systems’ toilet technology is a money and water saving proposition worth looking into. Fitting easily into a cupboard or against a wall, it recycles wastewater from baths, showers and some sinks and uses it to flush toilets. It can also extract heat from the greywater, feeding it back into the central heating system. Available in the UK, the reAqua and reAqua+ units can reduce water consumption by one-third. The company says a family of four will typically save 110,000 liters of water each year using a reAqua system.
These products can be used in retrofits and new buildings. A revised plumbing setup redirects wastewater from baths and showers through a compact reAqua filtration unit where it’s treated with a disinfectant. The treated water is then collected in a tank and piped on to supply the flushing water needs for multiple toilets. The company says users can expect savings of between £200 ($311) and £500($771) a year, with a typical payback time of three to seven years. It also produces energy savings and reduced CO2 emissions.
Along with other water conservation measures, it sounds like an all-around good investment for homeowners to make. Wonder if it will make it to the US anytime soon?
