Mr. Paul McGowan:

The information to hand indicates that the vast majority of water that goes into houses is not actually consumed. Approximately 10% or so is consumed and the remainder is used for other purposes. All of that water must be treated after leaving the premises. We took the view, therefore, that there would be a 100% discount in respect of supplies of water in but there would not be one in respect of water out. We believe this is a reasonable balance in terms of consumer interests.
