| Comment | Water isn’t much analogous in this scenario to electricity or broadband / fibre comms. Here are couple of reasons:
To use an electrical analogy, water can’t be transported more efficiently by stepping up the voltage to reduce current and thereby use small cables. This is what happens on the national grid. Water is voluminous, and moving lots of it a long way requires big pipes. Big pipes take up lots of space under roads etc and it’s thereby harder to provide redundancy in the system.
Second, unlike electricity / comms, water doesn’t travel at the speed of light of course - so when a fault is rectified it takes time for water to propagate through the system and reach all demand points (open taps). |
