Needed a grease trap NOW! so I made one

YouTube inspired grease trap. DIY grease trap made from simple easy to find components here in Australia. we installed an out door sink for convenience when cooking outside and need some place to send the waste water. been kitchen waste water this must go through a grease trap before been used for irrigation in my area with no time to wait I just made one for a small price of a new one with no waiting time. can be made in a day with drying time prior experience with tools/plumbing related things would help. this is just a demonstration and you need to check with your local area if this is appropriate.
