Ms Geraldine Tallon:

-----is that one is looking at the cost on a whole-life basis and one would expect to see that the contractor is pricing on such a basis and must price on the basis of operation and maintenance over 20 years. This has implications for the initial design and for the type of treatment and infrastructure, that is, the technology applied in the plant. There are advantages from the perspective of a DBOM operator on the whole-life basis but, equally, there are advantages for a local authority.
