Put in what your household actually does and this works out the year, and the next five years. Nothing is sent anywhere and there is nothing to sign up for.
Work out your own number
The figures below are typical for the UAE, not facts about your supplier. Change any of them to what you actually pay.
This is your own figures multiplied out — it is arithmetic, not a quote, and it does not include the refundable deposit sitting with your supplier. A gallon bottle is taken as 18.9 litres.
Where the method comes from
Anybody quoting one precise figure for what bottled water costs in the UAE has made it up: it depends on your supplier, your bottle size and how much your household drinks. So this does not quote a figure at you — it multiplies out your own. If you want the reasoning behind it, including where bottles genuinely work out cheaper and we say so, that is in what a UAE family really spends on bottled water.
If the sum comes out in favour of filtering, the maintenance page is where the plans and their prices are. For a villa the whole property is looked at and quoted after the visit, so there is no price to give you until somebody has been.
