What is the typical average water useage chaps per day for a typical window cleaner using wfp? in litres please.

Just trying to work out the cost of producing the water, im in a hard water area so looking at DI only and then RO&DI.

I was thinking of around 350 litres per day (max) for domestic properties only?

Thanks

Depends how many properties you want to do.
I can do around 20 on about 350 litres and I don't use a controller.

I average roughly 20 litres for a 3 bed semi house. I have found this can vary quite a bit though. Bare in mind though that when changing over and doing the first clean you will likely use at least 1.5 times the amount. Would be a good idea to clean the frames etc if your due to do them again before you change over (if you dont already).

If you're in a hard water area mate best to go for RO then DI as you will find the resin (stuff in the DI) will not last long at all. Mine comes out of the tap at around 340ppm. The RO takes it down to around 6ppm and the DI does the rest. Imagine how much extra the DI would have to do if it was cleaning 340ppm water. What tds is the water?

Some even use a water softener before the RO to give this longer life. Its more a choice of spend a bit more now to save later (RO and DI) or save a little now but pay more long term. (DI Only)

Alternatively mate to keep set up costs low for now if you're getting a tank you could post on here or ask locally a windie who produces there own water to buy from them. Usually only a few quid for a few hundred litres. If I had known I could have done that in the beginning I would have.

300 litres or so does me a full 8 hr shift , I have a 400 ltr tank and have very rarely ran out in over 2 yrs . Mike

working as 1 man we use just under 600l a day

as 2 we use around 700l

[Neil Gornall]

We use an average of around  25,000 - 30,000  Liters of pure each month.

And yes I am on a meter

steve a good idea to start with is just wfp tops on the changeover and trad ground floor windows.this allows you to ease yourself into wfp and not use too much water.

i use on average 300-350L per 6 hours "on the glass" time.i do trad some ground floor windows though.this is on maintainance cleans.sometimes its 400L on bigger jobs.

i have a 350L TANK and 2 barrels taking me up to 400L.Ill be putting a 500L TANK in my next van though.

stop using fairy as a detergent if you use it and switch to the pro detergents(gg3 and squeegee off combined works best for me)its not sticky and leaves less residue behind on the glass.

hope this helps

Thanks guys for the info, sounds about where I thought it would be.

I use Unger Professional cleaning fluid for widows, so not sticky like fairy, so hopefully most of my customer should be fine. I also clean all the sills and frames each time (always have done) so hopefully most of them wont be too dirty when I switch over to wfp. I will still trad some of these as suggested.

Thanks again guys for the advice, will definitely have to go down the route of RO & DI as hard water and so the resin would be way too expensive with DI only.

Cheers
