Mr. John Tierney:

To give the Deputy some of the background to this, it is covered in the benefits piece in his paper. The savings to the Exchequer of €2 billion are made of two things. It is taking the expenditure over time versus the income over time, allowing for the efficiencies that have been included - perhaps I will get Mr. John Dempsey to comment in this regard - as well as the fact that Irish Water must create the customer base to actually run this in terms of bringing in the income as well. Consequently, there are two pieces to it, which Mr. Dempsey will explain.
