Stormwater retention basins (SRBs) have been used in the City of Winnipeg since the early 1960s. The city and their land developers were in fact some of the earliest adopters of this technology. Early acceptance was based primarily on necessity as opposed aesthetics although it was recognized that retention basins did add to the visual appeal. The main reason why retention basins proliferated was because the land adjacent to our rivers and streams, which had previously afforded a cheap and easy drainage outlet, had by the 1960s, been exhausted. Our flat prairie landscape also made it very expensive to extend these land drainage systems further afield using conventional land drainage pipes.
