Q-2, r. 9.01 - Design code of a storm water management system eligible for a declaration of compliance

Section 46 Disposition versions

2020-12-31

46. To determine the suspended matter reduction performance of 2 storm water management works of a different nature installed in series, equation 3-12 must be used. Note that no reduction performance is recognized for a pretreatment work unless such a work is listed in Table 3.17.

Equation 3-12: P = A + B – [(A × B)/100]

where:

	P	=	Suspended matter reduction performance for 2 storm water management works installed in series (%); minimum value of 80%;
	A	=	Reduction performance of the storm water management work situated upstream in accordance with Table 3.17 (%);
	B	=	Reduction performance of the storm water management work situated downstream in accordance with Table 3.17 (%).
