The clogged drainage

The drainage in the backyard was clogged that the water in the kitchen sink wouldn’t go down properly. When I checked the drain junction it was clogged that I need to call a plumber to fix it. But at the outset I already know that it is a big job because the drainage pipe is about 10 meters and 15 meters going to the exit point.

When the plumber used a coiled metal to poke the interior of the  pipe that’s when we learned of the white objects that was obstructing the pipe. It was the lard as a result of the mixture of cooking oil and the liquid soap. That is just my hunch. At least the drainage is working well again.
