Title: Cheaper to buy pure water or make own??
Post by: Jakey boy on August 23, 2014, 10:16:18 pm
As I've just started using wfp, I've not got a RO yet so have been buying pure water from a local window cleaning shop, it's 3p a liter and always reads 000 tds.

My question is - is it cheaper to buy pure water than to maintain a RO system at home and also pay the higher water bill?

So far I've read that a lot of water is wasted with a RO and myself being on a water meter I've no idea how much my bill will go up?

Is it likely to work out more than 3p a litre on my water bill plus maintainance on an RO?

Thanks!

If it was cheaper to buy it where are the blokes that are selling it buying it from?

....yet.

Even on a meter only using resin (the most expensive way to do it) you should come in at less than 3ppl.

What's the TDS out of your tap, that will help others give you advice?
If it's low enough you may not need a R.O.

Sorry guys should of mentioned, I'm in colchester, very hard water worst in country or on par with a few others, it's put through an ro and di, my question is how much do people using a ro pay on average? Because if I can get pure water for 3p a litre locally which always reads 000tds then is this cheaper than maintaining an RO at home and paying higher water bills, bearing in mind 60% of water is wasted and I need 350-400 litres minimum a day?

It seems to me that 3p a litre is pretty good?

How much is your water per litre?
Get 2 jugs and measure how much waste it takes to make a litre of pure
Add them together and then you know how many litres in total it takes to make 1 litre of pure
Multiply that by the cost per litre from your water board and then make a decision

10 mins of faff means you know for definite which is cheaper...

Edit - just looked at the anglian water charges, you may be cheaper buying it!!!

Good idea, though haven't bought a RO yet, this is the dilemma, to but a RO or buy pure water direct... Gotta look at RO prices and see which RO is best etc. May just stick with buying it for the time being, then purchase a RO later down the line as a 2nd source from home.

I presume that the place that you are buying from will be using similar water to you. The majority of cost is likely to be purification not the meter.

What is your tap tds? Without that number you will just be making figures up.

You're usage is roughly the same as mine at 400ltrs per day - maths below

400 x 3p = £12 per day
£12 x 5 days = £60 per week
52 weeks x £60 = £3120 per annum

If you can buy R/O + other purification bits plus water bill for less than 3 grand per year then you're in front

my water bills is around £1000-1200/year including house hold in a very hard water area.I did have a £300 rebate though as  have a submetter fitted.
I also this month added a booster pump and can make 350 l in about 1 1/2 h which is pretty much 3 or 4 times quicker then before the pump,so should help massively in reducing the bill.I think i should have done it 2 years ago when i moved into the property.

Tell me more about the booster pump? Where to purchase how it works etc?

If you are doing it on household water supply you will need to add on sewage payment per litre

That'll be supply, what about your waste water charge? That's usually higher per litre.

If your pure to waste ratio is still the same, which it should be, then it makes no difference how long it takes to make the water, total consumption will still be the same.
