According to the survey report of the Ministry of Construction's "Current Situation and Problems of Village Human Settlement Environment", the household survey of 74 villages in 43 counties of 9 representative provinces in my country shows that 96% of the villages have no drainage channels and sewage treatment systems. Production and domestic sewage are discharged at will; 89% of the villages dump garbage in front of and behind houses, beside pits and roads, or even in water sources, spillways, and ponds inside and outside the village. No one is responsible for garbage collection and treatment. At present, more than 25 million tons of domestic sewage are directly discharged in rural areas of the country every year, causing pollution of rivers and ponds, affecting the living environment of villagers, and seriously threatening the health of farmers.
