你看看下面这段话。我看得一个房子也没有,不过我觉得应该不是大问题。95年的房子,如果地下室没有进过水,说明房子没问题。再者说了,好像是需要专家决定要不要修建。 ' h# ]6 @3 M; q" y3 T" Y4 r5 f2 r7 ^7 g, P3 g
In newer areas the sump pump discharges onto the ground, with the exception of areas that have a very high ground water table, or those adjacent to a lake, ravine or river. In those areas, sump pumps must connect to a storm service pipe to minimize soil erosion. A geotechnical engineer determines if this is necessary before the area is developed.
