sewage pit
英 美
We do not have a sewage system so we discharge our wastewater into a pit beside the house and then into the street once it is full. We do this with our own hands.
这里并没有排污系统,我们只有亲手将污水排放在房子旁边的一条坑子,到坑子满溢,就排放到街上。
Sewage flows through coarse bar screen and into inlet pump station drop pit, then is lifted to fine bar screen by drowned pumps.
经过粗格栅污水汇入进水泵站集水坑中,再由潜水泵提升至细格栅进水管。
