"That's exactly why a sediment trap was mentioned, to stop it ending up in the tank."

Physical impossibility if there is a reasonable amount of water flowing.

Ever heard of the Nile Plains. Created only when the river stops flowing fast enough to deposit the silt.

"No need for diverter valves and switching them over when it rains."

Much more fool proof, and healthier, to have a diverter valve, than rinsing, cleaning,

draining putrid, stagnant water, which you may well forget to do, and all your dead creatures

will end up in your drinking water. You obviously have no idea of the mechanics of water flow.
