A sump pump is part of a building's foundation drainage system and it has been a requirement since 1988. * O4 e, F% H5 s4 b7 n9 C/ ~# x) O) [! g- R0 l- t1 i) | http://www.edmonton.ca/for_resid ... ps-residential.aspx
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。 & O1 c7 G1 X0 o( s( V& L, x- S% _+ i! A2 z( z( L1 f% ?1 l. k0 ]
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.
