According to the Water Code of Russia, the site may be no closer to the reservoir than 150 m. To build a house on it, there must be a central sewage and water supply on the site. It is impossible to build a house in the premium zone. It includes the Earth located no further than 50 m from the reservoir. If the house is bought from a built person, then he risks losing his property. That is why, if you decide to buy a land plot from the reservoir, you must take care of the legal support of the sale transaction. It is advisable to entrust the examination of documents to a specialist, because many regulatory documents in Russia limit the possibility of using such sites or building houses on them.
