Technological choices

In some cases, the technological choices might have been less successful. Example of these are lead pipes, used in the antique and continued to be used in house connections until recently. water supply and sanitation systems need constant maintenance and adequate rehabilitation. This was already seen in the Roman aqueducts: calcium carbonate incrustation formed inside the conduits needed constant removal, while otherwise stopping the water flow. The same is true for the modern systems, the maintenance of them must be taken care of otherwise they do not function properly. The bigger problem is related to the need of constant replacement and fixing.

One long-term debatable issue has, and still is, what source to use, whether to use ground or surface water as raw water for community purposes. Surface water was needed to be used in bigger systems, but for smaller systems, ground water was commonly used. This is connected to the current question, how far is it economically possible to expand the systems. Once the systems expand other problems such as being over exposed are to be considered.
