Another newbie question regarding getting rid of koi waste from bottom drains in my planned pond.

Can I have all the bottom drains connected to a sump chamber that is not connected to the filtration system. Basically, just saying alooooooooha to the koi doots without having to circulate dirty waste water within the system. And instead incorporate a series of piping that will take pond water out from say the bottom one third of the pond directly to the pre-filtration system, then the filter(s) then a trickle tower and finally back to the pond? Is this an acceptable practice? Are there any disadvantages of a setup like this? Thanks again.
