The second option is no less troublesome and costly, but it ensures independence from the local enterprise — water supplier. For example, hot water supply of a country house can be arranged by obtaining water on a land plot or in the immediate vicinity of it. It can be an open reservoir if the water in it has passed all the examinations and is allowed for use in the household and everyday life. Another option is the use of an artesian well. The water extracted from it is distinguished by special purity and freshness.
