A sump pump is part of a building's foundation drainage system and it has been a requirement since 1988. 9 G" m9 G" j# n% `# |6 _% c/ h6 B3 {# h: g 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。 6 j) j* B" c8 H7 b! v+ n+ \1 m1 O0 t 1 q& A% a* A9 v/ r% Z5 ^ r- pIn 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.
