A lot of these old houses don't have water/don't have potable water so the residents use pumps located in the streets. They also don't have indoor plumbing so still have outdoor toilets (small shed looking thing over the fence, according to my CS host).
[Actually if you trust a lot of people then you shouldn't drink the water in most cities in Russia]
*Map location incorrect.
