Why doesn the City of Redmond build a stormwater treatment plant?
The variation in rainfall amounts and runoff volume would make a stormwater treatment plant economically infeasible. Rainfall not only falls in varying amounts, but also falls in varying quantities from one side of the City of Redmond to the other. In many storm events runoff volumes can be excessive. In particular, in developed areas small rainfall events can generate large amounts of runoff. We also have hundreds of outfalls to miles of streams.
