Where can I find irrigation pipeline check valve models that have been certified or approved for use in chemigation systems in Nebraska?
A list of certified irrigation pipeline check valves can be requested from the NDEQ’s Agriculture Section or you can go to the NDEQ web site (go to www.ndeq.state.ne.us, click on “NDEQ Programs,” then “Agriculture Programs,” “Chemigation Program,” “Applications, Forms, and Publications,” then finally, on “Certified Chemigation Check Valve Models and Manufacturers”).
