A sump pump is part of a building's foundation drainage system and it has been a requirement since 1988. / [% T' H4 C( I8 G" |# r: _. N2 |' R6 s" @7 }0 ] 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。- m% M; G" P7 O

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.
