Treated Water Pipeline

“Treated Water Pipeline” (TWP) is the term used to describe the 323 miles of pipe that will be used to transmit treated water from the treatment plant to the 20 members.  Sizes of the pipe range from as large as 54″ diameter to as small as 6″.  A series of booster pump stations and storage reservoirs will be located along the TWP.  The backbone of the TWP is the 54″ diameter “trunk line” that runs from the treatment plant to the reservoirs near Tea.  The TWP projects to date are listed below in chronological order.  Depending on available funding, there were times when a planned project was made larger or smaller so some segments have an “A” and “B” designation.
