But so much can be automated to a point. For example, garbage collection: Cities have already been saving money by putting in 'smart' cans/compactors (that are solar powered). No one needs to check every can, they just go along and get the ones that are full enough. Cities have also done things like standardize trash can so the machine takes care of the dumping. So many places now only have 2 people per truck instead of the 3 when I was younger. We use sensors for water treatment plants (and possibly for water delivery), software for some public transport when they do such a thing, devices to measure road traffic, and machines that automate much of road building. I'm going to guess that there are lots of these sorts of small things these. You can also simply start doing more of it as a city instead of contracting it out, but I suppose this isn't really technological.
