TOWN OF NEW CASTLE
W.T.P. CAPACITY (8-1-95)

(EQUATING FLOW TO EQR'S)

NOTE: THIS CALCULATION WILL DEFINE THE NUMBER OF EQR'S THAT THE TOWN
CAN SUPPORT WITH THE CURRENT CAPACITY OF THE WATER TREATMENT PLANT.

THIS CALCULATION IN FACT CONSIDERS THE IDEAL CAPACITY, ASSUMING A
LOW TURBIDITY IN EAST ELK CREEK (IE., JULY THROUGH MID MAY).

SKIP MARINO IS REPORTING THAT THE PLANT CAPACITY UNDER THIS SCENARIO IS 522 GPM.

DETERMINE THE NUMBER OF UNITS THAT THE TOWN CAN SUPPORT BASED UPON A CERTAIN CFS.

EQUATE FLOW RATE (CFS) TO GALLONS PER MINUTE (GPM)
(USE 60 SEC/MIN * 7.48 GALUCF FACTOR)

1.1631 CFS
521.9993 GPM

EQUATE GPM FLOW TO GALLONS PER DAY (GPD)
(USE 60 MIN/HR*24 HRlDAY FACTOR)

521.9993 GPM =

751679 GPD

FACTOR PEAK DAY SUMMER FLOW INTO AVERAGE DAY SUMMER FLOW:
(DIVIDE PEAK BY A FACTOR OF 1.5)

AVERAGE DAY SUMMER FLOW: 501119.3 GPD

EQUATE AVERAGE DAY SUMMER FLOW TO EQR'S (EQUIVALENT FLOW UNITS):
(THIS ASSUMES AN EQR IS 523 GPD-VERIFIED BY COMPUTATIONS LATER)

NUMBER OF EQR'S SUPPORTED BY FLOW: 958.1631 UNITS

PLANT CAPACITY UNDER IDEAL CONDmONS= 958 EQR'S
