I've been trying to find the Southern California [Orange County?] project - somewhat controversial, that reclaims 'toilet water' into drinkable tap water. If someone could link me to the story, I'd appreciate it. MRobertFlick (talk) 17:24, 14 February 2009 (UTC)Reply

First flush also is a term used for the spring harvest of tea leaves (second flush being the summer harvest). Not sure if that should be included; have no citations for it Da Next Pope (talk) 15:25, 29 October 2009 (UTC)Reply

The most stringent definition of first flush, I know of, is that 80 % of the pollutant mass are expected to be transported within 20 % of the initial runoff volume, Urbonas and Stahre (1993) and Bertrand-Krajewski et al. (1998). Another less common definition is Barbosa and Hvitved-Jacobsen (1999) that suggested first flush occur when 50 % of the total volume carries 61 % to 69 % of the total solids. Do you know of others? I also suggest that it would be worth to notice in the article that the first flush phenomena may occur for one pollutant but not for others during the same run-off event.
