White paper on protecting drinking water Failure to use inflow prevention can put the public at risk from contaminated drinking water. Val-Matic’s white paper Protecting Drinking Water Pipelines with Inflow Prevention explains this in more detail. selection affects energy consumption in pumping systems, the program takes specific application information entered by the user, and uses it to calculate headloss and 40-year energy costs for various valve types.

and downstream pipe reducers. The scope of the energy cost calculator also includes larger AWWA ball and eccentric plug valves up to 72" in size. Val-Matic Valve & Manufacturing Corp – USA valves@valmatic.com www.valmatic.com

Smaller than line size valves can also be evaluated with consideration to the headloss from the upstream

With the heightened demand for security and safe drinking water, inflow prevention is important because air valves and reservoir vents are vulnerable to flood contamination as well as malicious tampering. The use of vent pipes can worsen the problem by allowing cold air to enter the valve and potentially make it inoperable due to freezing, and directly exposing the pipeline to the outside and malicious tampering. AWWA C514 inflow preventers can be applied to new or existing air valves and reservoir vents to mitigate these threats. Val-Matic has also introduced an energy cost calculator for valves. Since valve
