You have to have a new system - your not allowed 'holes in the floor'
Mine cost me 30,000 just for the tank - then there was the 3/4 km of soak away pipes - as we dont have a running stream so couldnt use a reed bed system
We do have 5 showers mind and 6 toilets.
You may also be asked to have a disabled area as we were for equal opportunities
When you get it going - also look at Airbnb - we do loads of booking through it
Good luck with it
