A carefully engineered system that uses layers of different materials- pebbles, charcoal, and sand can be built into the tank/plumbing system for the houses. Such a system will utilize the natural ability of microbial biofilms to filter the water. In fact, such systems are already being used in many parts of the world. The natural filter components might need some replacement/maintenance though, and the water needs to be constantly recirculated into the system for purification.

Mikhail Korsanov As far as I know, we cannot completely omit the necessity to maintain/repair the system altogether. However, these are only periodic needs that we might have to attain every 4-to 5 years. This should not be a problem. I guess the need for replacement is due to the wear and tear of the system components, and also the residue accumulation.

Subash Chapagain 4-5 years is fine. How costly is this solution for today? How is it compared with widely spread systems? How good is it in cleaning the water?

A water well would be the most obvious choice if it has to last for decades without maintenance.
