Phil Hogan (Carlow-Kilkenny, Fine Gael)

The engineer signs up to the fact that the septic tank is working. That is what a professional does. An architect signs off that a house is in compliance with regulations, while an engineer signs a certificate of compliance indicating that the septic tank is working. If an inspection takes place in a few years at random, for example, in a high risk area, that is a separate issue. The engineer's report is all that is required to close the sale on a house.
