Releasing grey water to ground - Best Way?

Gravity works for me, usually.

We all have mishaps along the way, in my case I was leaving a site near Bispo (algarve west) but by grey valve was blocked up and I couldn't unclog it. Some of you will know that trying to unblock a drain valve, (under the back of the van in my case) sometimes it suddenly unblocks and dumps and you don't want to be in it's way.

My valve is marked up in German (Open / Closed) I forgot which was which and forgot to ensure it was closed. So I left it as-is and continued my journey westwards towards Spain.

So I am bimbling along the motorway when the interior of the Hymer filled up with the stink of grey water that had been marinating in the warm Portugese weather for about a week.

A glance in the rear view mirror advised me that the blocked valve was now clear and free while I had left a trail of smelly grey water behind me for a few miles.

Sorry, but there was nothing that I could have done to clean up the mess, but at least I knew that the valve was now working properly..

It was that pothole officer, thats wot did it, it must have dislodged the lever, was my prepared excuse in the case of a tap on the hard shoulder.

So I actually got round to knocking up a waste tank setup now.

I took advantage of an eBay 20% end of May discount offer and bought a container essentially the same as the one in Neils link (post below)

By the sound of it Dave you are hardly going to have any grey waste to deal with. Would a container you can close not do the job, one of those 25ltr black things with two caps so they can stand upright or lie flat? Only a few quid and it would just mean putting it out when you park

This is one I carry in case I need to drain some off where I cant empty: Waste Water Carrier

Added an old foam floor square to go between the container and the van floor; and some heavy duty 'strapping' (don't know the proper name) to keep in place, using the spare wheel supports and some additional fixings I added.

For draining, I used Hoselock fittings as cheap and will be easy to attach an extension hose to drain at home or at a suitable drain point.
I also fitted a hoselock connector onto the lid of one of my filter bottles I made up.
By pushing the connector on its own into the fitted outlet host extension, I can just drain the water

But can screw it into the filter bottle as well

I need to get a stopper on the end to stop it dripping out (the Hoselock 'Stop' fitting only fully works on pressurised system) but overall I think this should work ok, and for a total cost of around £15.


(I can swap the tank lid connector for a push-on one if I find the host is hanging too low, but I think it should be ok as it is. Or maybe see if there are hoselock right-angle fittings is another option?)

LIDL 1L Fruit Juice, use a Dremmel to cut vertical slits along the sides (can't see them in the photo) and in the bottom and will see what happens. If the water comes out pretty clean, I will likely, even when I have a grey tank, leave the tank outlet open when parked up in the random fields that are used in festivals (especially considering many of them are used for cow and sheep grazing).

Thanks to all for replies and comments :)

You've wasted a roll of flexi conduit there.

If you ever forget what this was used for and end up installing it somewhere, there is gonna be an eternal smell from the pipe.

That part was always temporary until I knew where the grey tank would go. Now cut to size. Only used for virtually clean water anyway and excess worked out at around £2.50 value :)
