Reading some of the other threads about disposing of wash water I thought I would show an idea to reduce the amount of biodiesel going out with the water.
I drain my water onto a paddock and was getting small dead patches of grass. By using the oil trap I have greatly reduced the problem and it surprised me how much bio collects in the drum.
I use a 20 litre drum with the top cut out, 3/4 inch poly fittings for all plumbing with some silicone for sealing.
The wash water enters at the top, any oil floats on the water to the top allowing water to pass out the bottom outlet rise up the pipe and flow away. The vertical drainpipe is vented to stop siphoning.When enough bio accumulates down to the level of the tap I drain it out and put it in the next batch for washing. The plate in the bottom helps stop mixing.
It works well because most of the wash water is oil free and only the last part has a lot of oil in it. It then has more time to seperate in the trap before the next batch of wash water.
I don't think we want to get a bad reputation for putting oil down the sewer or elsewhere even if in what may seem small amounts.
Hope this helps
