A sump pump is part of a building's foundation drainage system and it has been a requirement since 1988. - n `7 M7 T! e% K4 W# V# T% ^ " c+ l1 x8 B7 D! Fhttp://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 `% V$ q7 Q* h2 N" w+ Q0 S7 n3 n & m1 r: J' I: I& P1 tIn 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.
