The use of rain barrels (190L) across a watershed of 100 residential units has been modelled for a number of U.S. cities[http://onlinelibrary.wiley.com/doi/10.1111/jawr.12038/abstract]. In Philadelphia and Milwaukee (reflecting the most similar climates to Southern Ontario) the use of rain barrels for irrigation only, provided an annual stormwater reduction of less than 2%.
