RO/DI waste water

[anthonygf]

Someone mentioned trying to find a use for the waste water generated by our RO/DI system. I hope someone will find this useful and use this in their home.

Well I got this idea, collect the waste water in 5 gallon buckets and use to flush the toilets. Go ahead and laugh. I am using this method in the first bathroom where my RO/DI system is under the sink. Instead of going to the drain I have the waste line going to a bucket which sits in the tub with a float valve, I have a medium size pump in the bucket with a 3/4 inch hose going to the toilet tank. To control the pump I am using The Basement Watchdog, a universal sump pump float switch. Flush the toilet and the pump kicks in and fills the tank faster than the existing supply line, then shuts off when full. Works great, now to run a small line to the master bath for that toilet.

As you know, water level is very low in Lake Mead and water rates are going up next year. I have always disliked the amount of waste water our RO's put out, you don't know how great this makes me feel to conserve water even with the investment of a couple hundred dollars to set this up. Maybe I will save money in the next several years with the water rate increase.

Awesome idea!

You can also collect it in a large bin and run a line to your washing machine. Run a cheap pump you can turn on with your wifi or a switch and you are set. Washing machines can use a TON of water. Especially top loads. Someone already does this on R2R but I can't remember who

Tons of options out there to reuse that precious water and I hope more and more people come up with even more creative ways to save it

Yes. We use the toilet more than the washing machine, so I figured this is where I will start.

When my rodi was in my laundry room many years ago I would just run the waste water line into the washer tub. Unfortunately now my rodi isn’t near a bathroom or laundry room so now I just let the water go down the drain. I did install a second membrane to at least not waste as much.

Laundry … I used to save mine and bucket it into the washing machine .
seeing as I wash clothes in cold water anyways it never needed to be heated .

watering flowers or veggie gardens . But in the winter ( Canadian ) we would have a surplus of water from throughout the winter months

My RODI waste is plumbed into my 1000 litre water tank, along with the rainwater supply. This is used to supply the back yard tap, waters front and back through the watering system and all the manual watering we do.

The tank cost me more to setup than I will ever recover from reduced water bills (it does reduce them a little however) but I was happy to spend the money as I know it’s the ecologically right thing to do. A nice added bonus is that as this tank is also fed by rainwater, which is higher in nitrogen than mains supply, the plants enjoy it. The other minerals etc the RODI waste adds may also help, certainly don’t hurt. My wife always ensures she waters and sprays the indoor plants from this supply and gets better results by doing that.
