Ummm...I have a lavadero, which I use daily, in my laundry room in my 8th floor apartment in Mexico City. There is NOTHING like a lavadero to get one's clothes super-clean, to wash cleaning rags and mops, and to rinse out things you don't want to drip all over, like the measuring top of a bottle of detergent.
I have running water, a washer/dryer, and sewage lines--and need I say it isn't rural here in the middle of the Gran Tenochtitlán.
