A sump pump is part of a building's foundation drainage system and it has been a requirement since 1988. 5 Y1 v0 c) x9 c3 n% W; v2 c! Q5 J 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。 ' {% q# |( z8 p- u; h$ }# }; G& ^2 L, c3 b2 V1 d
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.
