The Regulations specify some VERY MINIMAL standards when using chambers when enhanced flow distribution (EFD) is REQUIRED.  However, the regulations do not appear to address instances where EFD is NOT REQUIRED but a designer actually provides EFD.  Therefore, a designer might, for example, provide a 600 gallon dose at a rate of up to 84 GPM with no pipe in the trenches (assume typical 2" force main and 4 bedroom dwelling).  This would be a ridiculous design and a recipe for a potential premature failure.  The regulations should specify a maximum pump dose and a maximum pumping rate for chamber systems.  I think chamber manufacturers would probably agree.  This needs to be addressed.
