Inner city stormwater control using a combination of best management practices

Abstract
Structural best management practices (BMPs) are now commonplace for stormwater management in new suburban developments; however, their installation in older central areas is limited. Here, the effect of disconnecting impervious areas from a combined sewer in favour of a new open stormwater system is investigated. The site, an inner city suburb of Malmo, Sweden, consists of council offices and apartment blocks separated by courtyards, roads and parking places. The BMPs range from green-roofs and open channels to detention ponds and their choice, size and location was dictated by cost, available land, safety and public expectations. The system was assessed by comparing synthetic hydrographs for the 1/2, 2, 5 and 10-year design-storms... (More)
Structural best management practices (BMPs) are now commonplace for stormwater management in new suburban developments; however, their installation in older central areas is limited. Here, the effect of disconnecting impervious areas from a combined sewer in favour of a new open stormwater system is investigated. The site, an inner city suburb of Malmo, Sweden, consists of council offices and apartment blocks separated by courtyards, roads and parking places. The BMPs range from green-roofs and open channels to detention ponds and their choice, size and location was dictated by cost, available land, safety and public expectations. The system was assessed by comparing synthetic hydrographs for the 1/2, 2, 5 and 10-year design-storms assuming wet and dry initial conditions. Direct runoff was simulated using the time-area method; and routing through the BMPs using PondPack. As the BMPs are in series, the outflow of one BMP became part of the inflow to the next in the system. Additionally, the water balance for the year 2001-2002 was investigated. It was found that the green-roofs are effective at lowering the total runoff from Augustenborg and that the ponds should successfully attenuate storm peak flows for even the 10-year rainfall.
