Municipal wastewater plants will spend $4.5 billion for valves in 2017. $3.4 billion will be for on/off valves, and the balance for control valves. This is the conclusion reached in Industrial Valves: World Markets published by the McIlvaine Company.
There are 1,900 active projects in the U.S. and Canada, which will require significant valve purchases. However, many of the projects are to replace or upgrade existing facilities rather than for additional needed capacity.
