Mr. Fintan Towey:

If I may first clarify or differentiate, the 23 applications related to the scheme announced by the Minister last year with a view to introducing public sewers to small towns and villages that do not have public wastewater treatment facilities. The DPI issue is separate. It relates to legacy issues whereby housing developments were built with developer-provided infrastructure that is not, at this point, fit for purpose. Quite a large number of these were identified in a study undertaken by the Department and they vary enormously in size. Some of them are quite small. Some are as small as five houses. There are also larger developments, in some cases involving hundreds of houses. That is the DPI scheme.
