Gallery: Sloan’s Innovative AQUS Grey Water Toilet System Recycles Your...


One of the oddest quirks in our homes is that we flush toilets with water good enough for drinking — and toilets consume on average 40% of a household’s water use. To address this issue Sloan Valve Company has been hard at work perfecting the AQUS water reclamation system, which takes your bathroom’s sink water and recycles it for flushing in your toilet. As a do-it-yourself project the kit takes about 1 hour to install and promises to save up to 6,000 gallons each year. Other than perhaps saving water in a bucket, the Aqus provides the simplest and most effective solution to reducing our water footprint — and it has garnered a lot of attention for its innovative design.

    Does anyone know where we can get one of these now?

    Should use the water used in the shower.

    Sloan\\\’s AQUS system – LINK IS BROKEN

    I would like to purchase an AQUS but Sloan has stopped distributing them. We have a serious drought in California. Perhaps someone from Sloan should contact Gov. Brown and see if you can get some state support to start manufacturing the AQUS again.

    The size of the tank takes up a lot of space in the vanity. Toilets today use 1.6 or 1.3 gal per flush; so you should be able to reduce the size of the storage tank to 3.5 gal instead of 5.5. A more compact unit would appeal to more homeowners.

    Nice concept however sad considering all links in this article are dead. Either the manufacturers are out of business or whoever manages their Website knows nothing about SEO and correcting 404’s.

    What is the maximum distance between the gray water tank and the toilet tank?
    Are there plans to make larger systems?

    I’ve seen a setup I prefer, where the sink is located on top of the toilet tank so the water drains in the tank automatically. I would invest in a sink that fits over my tank before one of these because it is more efficient and the space it takes up is usually unused anyway.

    The AQUS consumes about $0.60 worth of electricity per year. That is because it runs in low voltage (12 VDC) for only 1 per day.

    Great question when people are trying to figure out the true cost of water conservation.

    Nice idea… but what is the power consumption of the pump motor to fill cistern for complete flush?

    What a brilliant idea! Something simple and easy to install that any homeowner can use. Wish there were more products out there like this. Going green wouldn’t seem like such a big undertaking.

    For $189, the AQUS was designed to usher in lots of kinds of water reuse. It’s Plug-N-Play design was intended to get a larger population thinking about reusing water.

    I came up with the idea when I was 9 years old, patented the first prototype in 2000(30 yrs later). 11 yrs after that, people seem to be ready for a system like the AQUS.

    i could understand thi for bath or shower on next floor but who spend so much water in sink? :)

    This is a great solution for retrofitting existing toilets. While there are other solutions that will help you to reduce the amount of water needed per flush, this goes step further by recycling water already in the house.

    This remninds me of the Dyson strategy.
    Go to Japan. Find a successful, well incorperated technology. Return home. Sell it as your own revolutionary idea.

    It is a great water saver though, we should also by using the system for washing machines.

    great system. would love to have these in my parents house where we have 4 toilets flushing away tons of clean water.
