The countryside is vast and sparsely populated, and the villagers live scattered, and there are idle land in front of and behind the house. This situation can just make rural people do not need sewers. Because rainwater can flow along the yard to the vegetable fields in front of and behind the house. Or follow the ditch in front of the house and flow into the canal.
It is also very convenient to discharge the sewage generated by daily life in rural areas. Because there are vegetable fields in front of and behind the house, the sewage from washing clothes, vegetables and cooking pots can be poured into the vegetable fields. This can not only water vegetables, but also treat sewage simply and conveniently. Why not?
It is also a very simple thing to deal with feces in rural areas. A septic tank can be built behind the toilet. After the manure enters the septic tank and is fermented to a certain extent, it is a very good organic fertilizer and can be used to fertilize crops and vegetables. The vegetables grown in this way grow well, and there is no chemical fertilizer and pesticide residue, so they are really green and pollution-free vegetables.
But in recent years, with the development of resettlement, many places have carried out centralized resettlement. The residence of rural residents is also relatively concentrated. In this case, there must be sewers, and rainwater and domestic water must flow along the sewers. If there is no sewer, you must bury your own pipeline underground and connect it with the existing main pipeline. Conditional can build toilets and septic tanks. If there are no conditions, you can only choose to go to the public toilet.
To sum up, there are no sewers to build houses in rural areas. If the house is scattered, there is no need to build sewers at all, for the specific reasons mentioned above. If you live in a concentrated area, I suggest you try to build a sewer to connect with the existing main pipeline. The above is my answer, I hope it will help you, hee hee.
