This article is from May 2020; I wonder if DoorDash still does this.

My city’s giant landfills have clay liners that redirect the leachate to a treatment plant specifically for the purpose. The leachate literally flows into the plant constantly, it’s a huge amount.

I only know this because I worked there in my early 20s. It had the most horrifying smell like a fully fermented Diaper Genie poop-snake with strong sweet and sour notes that seemed to have flavour.

I got used to the smell at the regular waste water treatment plant, and at the dump in general, but the leachate plant was unbearable.

them robots took our jorbs!

This is everything you need to know to get going, OP.
