Understanding Shared Flow Terminology
The irrigation industry uses a variety of terms to describe water supplies, piping structures, and
flow scenarios. These terms may or may not have standard definitions in the industry. To avoid
confusion, please review Baseline’s definitions for some of these common terms.
flow device: A device that is capable of measuring water flow and water used, includes flow
sensors and flow meters
mainline: A pressurized pipe that supplies water from a point of connection (or from multiple
points of connection) to the valves
master valve (MV): A valve used to control when water is allowed to flow through that point of
connection. Often used to protect the landscape from flooding in case of a ruptured main or a
malfunctioning downstream valve.
normally closed master valve (NCMV): An automatic valve through which no water will flow unless
external influences are applied to cause the valve to open
normally open master valve (NOMV): An automatic valve through which water will flow unless
external influences are applied to close the valve
point of connection (POC): Also known as a water source. This term refers to the place where the
irrigation system is connected to a water supply. In the case of a system that has access to water
from multiple supplies, such as harvested rainwater, reclaimed water, and potable water, this term
is also used to distinguish one water supply from another. For example: POC 1, POC 2, etc.
