Can the drainage wells and sweet potato pits of rural houses in Beijing be put in the house?

Try not to put the drainage well at home, because the frequent use of the drainage well will have an impact on the foundation. Even if you put it outside, don't put it too close, otherwise it will have an impact. It is better to be more than 3 meters away from the wall. Putting the sweet potato cellar in the house depends on how high your Phnom Penh is, that is, how high the ground inside the house and the ground outside the house can be checked. If it is basically flat, there is no problem. If the foundation is high, don't put it near the wall, otherwise the sweet potato cellar will freeze easily in winter.
