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。 , ?. m1 g/ o4 N: i; w% d( |7 ?& a6 r. ~ 7 W) {" h7 u8 U: z1 Y ?: s( eIn 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.
