Plastic soakaway crates

To me, the alternative seems to be galvanised steel mesh crates, which also wash contaminants into the soil eventually. Plastic usually has to be in contact with damp/water for quite a while for any significant leeching to occur but once metal begins to rust it can deteriorate quite rapidly.
Maybe the answer lies in a natural pebble trench of some sort of soakaway?

I agree the so called old method of using clean rubble is surely best. Yet local authorities push the use of plastic crates. It did get me thinking. The rain water falls from the sky onto plastic roofs..runs through plastic gutters..through plastic drainage. What are we thinking!
Break down? If you are on about micro plastics, you are barking up the wrong tree.
Rainwater collect all kinds of shizzle before it ends up in collection reservoirs and always has. Its the reason we have water treatment plants.
I hate to be a bore but all of your drinking water is piped through plastic in any case.

'Clean rubble' lol. FFS.
Problem is Nige, rubble fill typically has a volume of 30% where plastic crates have a volume of 95%. So, for large systems, you'd be excavating three times as much soil. Also, most systems need to be cleanable, which isn't possible for rubble filled systems. Rubble fill is ok for the average extension but for anything else plastic is usually the only option.

A lot of gutter grids and manhole covers have been replaced by plastic as the metal ones were being stolen, hardly surprising when certain communities are allowed to do as they like e. Never thought about plastic particles being washed away, but it could be a problem as most surface water drains run straight into rivers. Mind you, most drainage pipes are now plastic, so what do we do now?
Plastic doesn't break down.
So all the world boffins are wrong then. Surely everything on earth breaks down even granite? I didn't consider the actual drinking supply being plastic in years to come major issues will develop from this.
No just you and your interpretation of trade and industrial plastic use.
