Large amount pollutants settle and accumulate in storm sewer when cleanout is not in time or available. Those sediments will re-suspend and discharge to receiving waters in wet weather. Contaminations in sewer stormwater come from both catchment and sewer. Discharge law of different source pollutants is analyzed in theory and with experimental results. Pollutant discharge law from catchment accords with exponential washoff model, but sediment pollutants in sewer fit rating curve washoff model well. Analysis shows that the more the sediments is, the weaker the first flush effects will be. It is better to control diffused pollution on sit (source control), for those stormwater quality facilities run with high efficiency as they are based on capture and treating first part of runoff. It is also important to intensify clean and maintenance of storm sewer system to avoid sediment and accumulation of contaminations.
