I agree with a lot of what has been said but at the same time I believe we have learned lessons about failing to plan. We need to know the ingredient that is different. There is reliance on the likes of the DART upgrade going ahead and on building capacity into treatment plants in regard to the zoning of land.

Many of these are interconnected. For instance, headroom is needed if the DART is to be upgraded, which involves rebuilding bridges and so on. All these components are important in understanding the timing. What components are being examined and do they differ from the original proposal? Is that detail part of a business case?
