It was a joke that you obviously missed.What do you think running a full flush house hold domestic toilet straight into a man whole drain, and it wont block up, and no one will notice, and no one will give a ****!
So, you plan to convert a trailer into a house and you think it will be okay to park your 'house' in the road and not move it? Do you think that will be allowed? You also want a very large septic tank to hold all your pîss, shît and other waste water. Have I got that correct? Do you know how a septic tank works? When it doesn’t work, how do you plan to empty it? I suggest you look that up as well as looking into getting planning permission for your house in the road before you go any further with this crackpot idea.
