Municipal drinking water and wastewater treatment facilities around the world will spend $54 billion this year for products and services involving flow control and treatment of air, gas, liquids and water, $21 billion of that for pumps and valves. This is the conclusion reached by the McIlvaine Company in Air/Gas/Water/Fluid Treatment and Control: World Market.
The ratio of pump to valve sales is higher in municipal drinking water than in municipal wastewater due to the greater number of treatment processes needed in wastewater treatment. Plant operators are slowly moving to automation which industrial plants have already adopted. This is increasing the demand for smart pumps and valves which can indicate performance and maintenance requirements.
