This is a rather difficult engineering system, which beginners cannot cope with. And if you want you to succeed correctly and with minimal costs, then it is better to entrust this business to professionals. Of course, in this system there is nothing super -complex and after some efforts you yourself can cope, but if you do not succeed the first time, you will have to buy again the material that you, without a doubt, ruin. And at the current prices it is expensive. And it is not yet known how the system will behave in the winter. So, it’s better not to take risks.
It only seems that the water supply to all residential buildings is the same. For example, you will need to arrange water plums for water, because in the winter, when you are in the city in a warm apartment, the system will defrost in your cold dacha and you will have to not only change it, but also save it from the flood. And in order for the drain to work well, the entire system will need to be installed under a certain slope, so that the water does not linger anywhere and all merges, otherwise where it will remain the problem.
Naturally, all these conditions are fulfilled with certain costs, which are required for additional equipment.
