Storm Pressurized Main

A pressurized main is a type of main line that is pressurized. Pressurized main is a concrete class. There are numerous types of pressurized mains in the water distribution model; they include air release, blow off, bypass, chemical injection, distribution main, interconnect, pipe bridge, sampling station, and transmission main. Transmission mains are large-diameter pipelines (24" or larger) that carry large quantities of raw water long distances from their source to a water treatment plant, then to the distribution grid system. Transmission mains generally run in a rather straight line from point to point. Lateral lines are not attached to transmission mains. Distribution mains are average-diameter pipes (4"–20") that transport potable water from transmission lines and redistribute it throughout an area. Lateral lines attach directly to distribution mains.
