Hi everyone, first post for a bit of a new-comer to caravaning. Just returned from a week away (in the rain!) where i noticed a number of vans using some sort of filter on their wastewater outlets and letting the filtered water drain away into the ground as apposed to using the likes of a wastemaster. However my searches on the internet have drawn blanks. Hoping someonr could help answer a few questions:- Are the filters home made? and if so, do all campsites allow the use of such filters? thanks in advance.
