Worth remembering, newfangled tech isn't always better, when it comes to water.
Wolverhampton's water (Severn Trent) is pumped from a series of connected boreholes.
Pretty sure it was either Bridgenorth/Cosford, the pumping station in question.
Water used to be pumped from the ground using a simple fixed speed pump, that had been in place since its inception, it had been decades since it last needed maintenance. This was replaced by a newfangled variable speed pump, to supposedly save money, but the 3-phase inverters were found to last just a few months between failure.
Something that was simple and had just worked for decades became very complex, and prone to regular failure, the inverters weren't cheap to replace either.
