It depends which runoff areyou talking about. Since you refer to N and P, I suppose you are talking about agriculture runoff, and you would like to avoid nutrient discharge in water bodies to limit the risk of eutrophication. If this is your case, I suggest you filter strips along the river to treat the runoff before it enter in the river, or constructed wetlands for agricultural runoff treatment

The question may not be only about agricultural runoff. Sewage overflow and septic tank seepage can contribute N and P. But I agree with the filter strip and constructed wetland recommendations, and also with Richard Ashley to consider SUDS (see also WSUD) solutions.
