A sump pump is part of a building's foundation drainage system and it has been a requirement since 1988. ; T2 _4 b6 t- @: a * ~* r# {+ D {7 dhttp://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。 . l: h( {9 h3 G/ s3 q1 l' S+ X2 Y% X. ~' r6 `. l% {* n5 R
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.
