HYDRAULIC CALCULATION PROCEDURE
A new section was added regarding hydraulic calculation procedures to
clarify where the hydraulic calculations should terminate. This new
section is located at 22.4.1.5 and states, "Hydraulic calculations
shall extend to the effective point of the water supply where the
characteristics of the water supply are known." The intent of this
section is to clarify where the calculation terminates for a looped
water supply and a connection to a dead end main. The two are handled
differently. The water supply data from a flow test can be carried to
any point between the flow (pitot pressure) and test hydrants (static
and residual pressures) for a looped system. The calculations for a
dead end main have to be continued to the test hydrant (static and
residual pressures). The purpose of this is that the residual
pressure is not really known past the flow hydrant. Thus the
calculations have to be taken to the test hydrant for a dead end main
connection.
