Infrastructure costs by pipe material

Which brings the financial results on this slide. I've just lumped all the CI and DI together under "unprotected metallic". That 1330 km still has 400 breaks per year costing us 1.9M Euros to fix. So we spend 4.8M Euros per year replacing it. We have also started spending 1.4M of the old replacement budget retrofitting it with cathodic protection, as a better value for money.

The YDI, by contrast, has never had a replacement and has only 20 breaks per year, plus a few hundred thousand for cathodic protection monitoring and anode replacement.

Now, at long last, and thank you for your patience, we arrive at your product. Late this year, we should install our 2000th kilometre of PVC pipe, and it has just one or two breaks per year, so obviously we never replace it. I mention that some year we will have to do a little cathodic protection on that part of the system, only because...
