Abstract

Low impact approaches to managing stormwater runoff are highly customizable and can be tailored to the opportunities and constraints unique to an individual site. But the persistent question remains “do they work”? To this end, the City of London has retained AECOM to monitor five separate LID installations throughout the City and to assess their year-round performance under typical operational conditions. Monitoring goals specific to each LID feature have guided the data collection methodology, and information pertaining to a range of volume reduction, exfiltration/drawdown, thermal, sediment removal and attenuation performance metrics have been assessed. In-pipe flow monitoring data from two separate Etobicoke-style exfiltration systems and an onsite rain gauge have been used to calibrate a PCSWMM model in order to further assess the peak flow and volume reduction performance of some LID features.
