Home RO Filters

500 l in 8 weeks is about 63 l/week. Add 80%, 109 l per week. If you pay 1 cent per liter, that’s a dollar a week for water. If you like you can put the ‘waste’ into the garden, as it has extra minerals that are beneficial, no poisons (your tap water is drinkable, yes?) so your ‘tomatoes’ will be more potent.

I pay far less than a cent per liter here.

Sure the RO system uses the extra water you mention. I would guess the RO water system at the store has the same waste involved.
For me, it's like the water I use for condensing steam and cooling wort. I have a well in the back yard and a septic tank in the front yard. I am just moving the water from back to front.

Yep, the waste water from the RO system at the water store goes to the same treatment plant that mine will go to

As I have a separate building for brewery work, I had a line run to it ( aka, a garden hose ) connected to the R/O system I bought from Buckeye Hydro. I was going to just do a charcoal filter system but to do what I wanted was about the same cost as R/O, so I went the R/O direction. I do have pretty good brewing water though. The system I bought has a float shut off, which I feed directly into my 18 gallon Anvil. I typically need about 11-12 gallons to get my 6.25-6.5 gallons of wort at the boil's end. I start with about 7-7.5 gallons and pump the rest into a Digiboil for sparge water. Often times I end up with 14-15 gallons by the time I shut off the water, so whatever's left I use for cleanup. I can fire up the water system the day before, set the kettle timer and I'm practically ready to go after morning coffee the next day.
