This is what sump pit/pump designed for: Collect all underground water around your house foundation and pump it out to the outside drainage system before it ever has a chance to flood your basement.
我一直以为那是把屋里的水排到外面去。如果是排房子周围的水,那一定有个进水管把外面的水引入sump pump了,那外面夹着泥沙的脏水岂不是先进了屋内的排水系统吗。 F6 ]( l. {# z8 L( P5 Y* X. C m
再有,与其把外面的水引进来,再排到排水系统,为什么不直接从外面直接排到排水系统啊?Edmonton市政府要求做grading,理论上房子周围的水应该可以流到远离房子的低处,如果在那弄个雨水井,好像更合逻辑。8 D! Z/ y- u: E. e [/ m% q
