Northern Ireland Water (NIW) is the Government-owned trading company with responsibility for the provision of water and sewerage services throughout Northern Ireland.
The company receives its revenue partly through charges levied on non-domestic business customers along with an operating subsidy in lieu of domestic charges received from the Department for Regional Development (DRD).
The details in this statistical table are drawn from the Regulatory Accounts which differ significantly (in conceptual terms) from the presentation in the Statutory Accounts.
The operating subsidy in 2009-10 was £257m compared to £263m in 2010-11 and £269m in 2011-12.
Nominally, this approximates to the revenue that would be needed from any water charges on domestic households, whether that that was raised as specific charges or attributed as a contribution from regional rates.
As a wholly-owned Government trading organisation, NIW draws its new capital resources through the DRD as part of capital spending by the NI Executive.
In 2009-10, outstanding borrowing increased by a further £170m to reach £628m at the end of March 2010.
In the two more recent years, successively, NIW borrowed £110m and a further £70m.
