§ 25-116. Formula for computing payments.

ICR = Qf / Qd × QU + BODf / BODd + BOD _u × SSf / SSd × SS _u + Nf / Nd × N _u × ;frac;P

Where:

ICR	=	Cost to be recovered from an industrial user ($/billing period).
Qf	=	The sum of the federal grant costs allocable to flow capacity ($).
Qd	=	The design flow capacity of the treatment works (gallons/day).
Qu	=	The average quarterly waste water flow contributed by the user during the billing period (gallons/day).
BOD f	=	The sum of the federal grant costs allocable to BOD 5 capacity ($).
BOD d	=	The design BOD 5 capacity of the treatment works (pounds/day).
BOD u	=	The average daily poundage of five-day biochemical oxygen demand twenty (20) degrees contributed by the user during the billing period (pounds/day).
SS f	=	The sum of the federal grant cost allocable to suspended solids capacity ($).
SS d	=	The design suspended solids capacity of the treatment works (pounds/day).
SS u	=	The average daily poundage of suspended solids contributed by the user during the billing period (pounds/day).
N f	=	The sum of the federal grant costs allocable to nitrogen capacity ($).
N d	=	The design nitrogen capacity of the treatment works (pounds/day).
N u	=	The average daily poundage of nitrogen as N contributed by the user during the billing period (pounds/day).
P	=	Length of the billing period (days).
R	=	Length of the cost recovery period (days).
