Is it possible to build a car wash next to a water pipe?

Hello. Previously, there existed for the organization of such norms SNiP 2.07.01-89, in principle, not much has changed, but now it is in the updated version of SP 42.13330.2011 “Urban planning. Planning and development of urban and rural settlements. ”

This document has a subparagraph 12.35, which indicates the horizontal distances in the light of underground engineering networks to various buildings and structures. Table 15 is attached to determine the distance and it is clear that the distance to the foundations of buildings is 5 meters, to the fences of enterprises - 3 meters. But in your case, this is an object of non-capital construction, that is, not a stationary structure, therefore completely different standards apply to it.

I looked at current relevant laws and found the Federal Law of December 28, 2009 N 381-ФЗ (as amended on December 25, 2018) “On the Basics of State Regulation of Trade Activities in the Russian Federation”. Article 10. Features of the placement of non-stationary trading objects:

«3. The layout of non-stationary trading facilities is developed and approved by the local government, determined in accordance with the charter of the municipality, in the manner established by the authorized executive body of the constituent entity of the Russian Federation».

That is, the location and in general the procedure for registering an object is coordinated with local authorities and a charter developed by a specific district that does not contradict the norms of the law.

Again, on the Internet, I easily found several of these city charters and found in them the following subclause:

«In cases of placement of a temporary non-capital object on the routes of engineering networks or in their security zones - coordination of the placement of a temporary object with the owners or balance holders of such networks».

That is, you do not need to search for a specific document. There is no law governing the location of a mobile structure relative to utility networks. Here you will need an agreement with the balance holders, which is quite logical.

Resource provider engineers know the specific location of the networks, how many meters they need for unhindered repair access due to terrain and landscape features. There will be questions for you, most likely, about your car wash - which cars, how many washing places, the composition of the soil and the condition of the engineering networks will probably be taken into account. That is, you need to decide and clarify this issue directly in Vodokanal or in administrative bodies. Good luck
