Waste disposal points in Wales

The only way you can dispose of grey waste water/fill fresh water tanks and empty toilet cassettes on club sites is to book onto the site and pay for a night's stay.

However I can certainly imagine with some great certainty and know what the OP is asking.

So, to save time:

This isn't offered at the moment on club sites due to the club's view that it does not encourage wild camping. As said you will have to stay at least one night, or pay the fee for one night. A cheaper way might to pay for one's night stay on a CL.

I believe the CCC does allow this so perhaps consider joining them? Others might be along to say where other non club sites or places allow this? And perhaps campaign to get the club to change its mind but this won't help atm

PS A new bug in the CT software?

Just for completeness, I think the last time this was aired the club also said it would add congestion to sites as well? And no you can't use the showers either.

There has been an article in Norfolk requesting that motor caravans do not use public toilets for emptying their chemical toilets. as some are not on main sewer system

But you can with C&CC.
