How does everyone deal with washing machinery off back at yards in this age of environmental awareness .... I would like to put one in at the new yard but hardly dare ask :eek: :D

I am currently waiting for the E.A to remove the waste transfer license from my yard then I am going to shamelessly copy Trax's system.

Three chambers. Water/Shit/Oil mix goes into first chamber... heavy stuff sinks in a sump, oil and water pass through a pipe that is at surface/inlet level. leaving the mud and crap behind. Next chamber the water filters down to a pipe in the bottom, whilst the oil floats on top.

Final chamber traps any remaining silt.

Depends what your dealing with just oil or chemicals bio beds can deal with anything
Just a concrete pad with a speedbump cast round it then everything goes out through one drain no leakage

Sounds a proper job that !

I will be looking to do something along those lines - with a basket or something in the first to lift mud/gravel out in... or sized so a mini can clean it out.

Make it so a Mini can clean it out. Tim's had a steel Bucket originally apparently but alas the silt would always pack under it and around it. Roadsweeper was the boy for cleaning it. :D

The main thing with interceptors seems to be making them easy to clean. If it is a difficult/expensive job you will be tempted to leave it a bit longer and before you know it there will be problems.

We have a 14m x 8m concrete pad with falls to a 1.5m x 2.5m by 1.5m deep catch pit in the centre with a outlet to a fibreglass 3 chamber separater. The grating on the catch pit we just lift off and dig out the silt with a digger, it works well for us.

Cheers for the info - sorted.
