Grease Trap Installation Charges

Hello friends,



I am searching at opening a vegetable cafe in Gold Coast and expecting to find somebody here who recently got a Grease Trap set up in Gold Coast area



In process of discussing lease with property owner - all good except landlord is identified on not setting up grease trap, he is prepared to give 5 months rent free instead ( Lease is 3 + 3 + 3) and even put a toilet in



The property broker suggested a plumber and upon phone conversation he suggested that the city of GC does not allow above ground grease traps and therefore has to be 'burried'. This worries me as I know that searching it in is going to improve costs directly away. I am planning to council in the next couple of days to ensure his claim, however if any person here can give me an plan how much they invested on getting a trap in and set up ( inc attaching to kitchen) - it will be of good help. The trap i'm after to be made from plastic 1100 ltr and the backyard is a garden so i am hoping soft soil - no rocks



Thanks! in advance guys :D
