There’s an urban legend in NYC that every incoming mayor since something like 1890 gets a letter, handed down from mayor to mayor, signed by all of the mayors, that says something like, and I am guessing here, but it is supposedly a very short letter: Do not #%{>€!# with the sewer system. You may be tempted to, because it works so well it is invisible, to reduce its budget, or to overhaul it, or something. Do not. Fund it. Hire extremely competent people to run it, and do not replace them. Do not #%*|!%# with the sewer.
