Would the strainer be a substitute for return bends on pendents?

Recently I have been asked to put in line strainers in the pump suction. Are they required when you have intake screens? The reservoir is being feed by a well. The reservoir is also lined with a membrane. My take is if any debris gets by the intake screens, it would be too small to damage the pump. A y strainer after the pump would filter any debris that might be detrimental to sprinkler performance. Any comments or suggestions would be appreciated.
