It’s not easily solved at all, because the hard part is planning and building and maintaining the infrastructure. Something local governments frequently reveal themselves incapable of doing, even when they’re sufficiently financed. That’s before you have to contend with the incentives of governance bodies often being not exactly aligned with that outcome. Responsible management of basic services isn’t usually a platform that drives voter engagement. Local governments are incentivised to minimise how much they spend on basic infrastructure, not intentionally create new demand for it.
