The answer to competing water and sewage companies is simple

stop trying to pipe water and sewage for multiple homes, or at least allow some to "opt-out" of the local monopoly and dig their own well, and install their own sceptic system. (or install composting toilets)

Many of the seeming problems with servicing multiple customers which implies monopoly lie with the first errant assumption that the best or only method is to serve multiple customers at once.
