Will I regret an uphill drain pipe?

I'm about to start excavating a pond 4' deep with a 55 gal drum filter
(drums 3' high; jj's design). One nagging doubt I have is about the
pipe from the bottom drain to the filter. It'll have to run uphill at
least 1.5' in order to enter the filter. Seems to me that with enough
flow I shouldn't have problems with the pipe clogging, but I'd feel
better about it if the pipe ran down rather than up.

I've considered constructing an extra deep drum from two drums so the
bottom of the drum is below the bottom of the pond, but perhaps this
isn't necessary.

Any opinions?

To clarify. You have a bottom drain in a pond, and the output of the drain
is 1.5' above drain, which means sediment will eventually collect into
bottom of the pipe. If you design the output into the drum well, every so
often you can backwash the system by turning off the pump and letting the
water flow back into the pond and push the muck back out

Maybe drill a hole near the bottom of the drum, fill the water near the
bottom, so when shut off the pump, you have a few feet of water pressure to
back wash any built up sediment in the pipes.
