Now reg don't allow that waste water to be flushed into the system and must be collected and removed by certified/qualified companies.

Shot there for many years, I left after in fighting on the H&S Committee because the only way to do things, is the right way, which isn't necessarily the cheapest way I don't know where they are now with this. Birkenhead Indoor range under the sports stadium suffered the same problem, couldn't decontaminate/clean correctly and they closed down. YouthTown decontamination is a biggie too.

Very much agree with your points.
For once the yanks have some good ideas for indoor ranges - air and contamination.
The top of my list at the moment, is a snail type target area. Imagine a V on its side, and a circular portion at the back, off set.



As mentioned, not cheap at all!! But do it once do it right.

Plus positive air movement down range, polished floors, painted walls, no dust collection areas, etc.....

Police range at Porirua was designed to have air be pumped through from behind the shooters and sucked in at the end behind the butts

If the inlet and outlet holes are evenly sized and distributed across their respective ends then the air flows in a manner called "plug flow" which has little turbulence but steady from behind the shooters and carries away any fumes and whatnot

Also was designed for use with frangible rounds FWIW

Dunno how well it worked in the end as I only saw it at the early stages but it's an idea

The snail trap looks really good
