2023年9月26日 · In order to manage urban stormwater runoff effectively, detention ponds and on-site detention (OSD) systems were also significant MSMA components. OSD systems, supported by MSMA, offer space-efficient solutions, particularly in urban areas, while detention ponds regulate peak flows and lessen the risk of flooding.

2023年5月30日 · OSD is suitable to be used for a development area of less than 5 ha, while Pond is used for an area larger than 5 ha. However, MSMA 2nd Edition has come out with a shorter, simplified method for OSD called “Simplified Method” and is often encouraged by the authority to use this new method.

2022年11月2日 · The estimation of Permissible Site Discharge (PSD) and Site Storage Requirement (SSR) for On-site detention (OSD) is based on the Swinburne Method developed at the Swinburne University of Technology in Melbourne, Australia.

2022年9月14日 · Click on the Pond Sizing tab to proceed on pond sizing design. Select the type of the pond (rectangular ,circular or irregular). Input the dimension of the pond type such as length , width , and depth to calculate the volume.

This chapter provides simplified guidelines for the design of on-site detention (OSD) facilities. OSD may be provided as above-ground storages, below-ground storages, or a combination of both within a property boundary. Above-ground storages typically are located in lawns/gardens, car parking/driveway areas, rooftop and tanks.
