Toilet technology recycles water, produces waste heat

Toilet technology recycles water, produces waste heat

ReAqua Systems’ toilet technology recycles wastewater from baths, showers and some sinks for use in flushing toilets ? and can extract heat from the greywater, feeding it back into the central heating system. The reAqua and reAqua+ units, available in the UK, both reduce water consumption by a third, while the latter (which has the optional heat recovery from greywater) also enables a two-fold reduction in CO2 emissions.

The two products can be used in retrofits and new buildings. A revised plumbing setup takes all wastewater form baths and showers, redirecting it through a compact reAqua filtration unit where it is treated with a disinfectant. This treated water is collected in a tank and piped on, as required, to supply all the flushing water needs for multiple toilets.

End users can expect savings on metered water bills between £200 and £500 a year, with a typical payback time of three to seven years, the company says. Fitting a reAqua+ system typically offers a projected lifetime saving between £4,000 and £10,000 per unit.
