population). Data were collected from the “PLC” of water treatment plant pump sta-
tions. Water hammer models of the Rasht city pipeline guided route selection, con-
ceptual and detailed design of pipeline. The pipeline is included water treatment plant
pump station (in the start of water transmission), 3.595 km of 2*1,200 mm diameter
pre-stressed pipes and one 50,000 m

reservoir (at the end of water transmission).
All of these parts have been tied into existing water networks. Long-distance water
transmission lines must be economical, reliable and expandable. So this study was
retained to provide hydraulic input to a network-wide optimization and risk-reduction
strategy for Rasht city main pipeline. Research track record includes multi-booster
pressurized lines with surge protection ranging from check valves to gas vessels. This
study included particular expertise designing pressurized and pipeline segments, re-
ducing unaccounted for water “UFW” flow where possible to reduce energy costs.
Several experiences demonstrated to ensure reliable water transmission for the Rasht
city main pipeline.
The water hammer phenomena investigation due to fluid condition
was the main objective of this research. It formed by investigation of relation be-
tween: P-surge pressure(as a function or dependent variable with nomenclature “Y”)
and several factors(such as independent variables with nomenclature “X”) such as:
