The price per cubic metre depends on which water board supply you and also whether you are on mains sewers too.
I'm not on a metre and we have a cesspit for our waste.
My own water bill per year (this current year) was £99.00.
Other costs such as replacement membranes, resin and pre-filters also need to be factored in of course, and there is not going to be just a single figure that will suit all people, that will also depend on water hardness, water pressure, how well you care and maintain your equipment.
As John says;

Generally it seems the actual cost of the water is being ignored in the costing and running of the business!
Only asking because I have not seen a topic on water costs mentioned here.

These costs are almost hidden in some respects, a lot just don't think about it, they see they are doing more work per hour and end out charging less than they were before porely because they are quicker
In some instances people are going to spend several thousand pounds on equipment, they will have a business with higher running costs and yet they will drop their prices through the floor to be more competitive than the opposition!
