I'm very impressed with the organisation of your Government, and I'm completely serious in saying that.Nope we gave up on rivets a long time ago... There is a restaurant moored on the Liffey which was I understand the last riveted boat made in Ireland.. 1953 i believe. Much more RIVIT these days. The kind of advice would be , might it be a good idea to replace the 170 year old cast iron water mains, leaking 20% of the water with new slimline plastic liners, inserted into them. These cast iron pipes having rusted to a scale,but still defining a tube.
Not much votes in it, not much qudos, unglamorous ,but it does need lots of tables and sheets of data showing why it might be more cost effective than building a new system.
You wouldn't get far tendering such reports to our Government, they don't concern themselves in matters so detailed, though to be fair to them , neither do the privatised industries that run potable water supplies in this country, which is why such a huge volume of water is lost to leaks.
