Thanks guys, lots to think about, but first step is to get details about his pond, and what condition it's in. Second step is to see if the irrigation is pump fed or gravity fed. I'll try to get up to his place in the next week or two, and see what his plans are for the actual irrigation process. That'll narrow down options. I fell out when I found out what elderberries were worth. He's also building a complete processing building to keep as much as possible in house.

Scott and Kenny, thanks for the chem advice.

Rod, just off the top of my head, I was thinking a screened tub like Scott mentioned would handle the majority of the big stuff, then have some type of secondary filter for the smallest stuff. Augie's right about the orifices, so being able to flush the tubing and easily clean out the orifices would be a must also.
