Waste disposal in England

[Duncan2580]

Hi
Looking to find an app or website that tells you were you can dispose of your chemical toilet and collect water in England . I know Scotland has a website called campa which I have used and I know some campsites let you on to use this facility for a small amount, but it would be good to hear your feedback.
Thanks in advice

The Camping and Caravanning Club provide service stop off points for members. A bit pricey but you may stay for up to three hours and use all the site facilities during that time. https://www.campingandcaravanningclub.co.uk/campsites/facilities/service-stop-off-points/
