Waste fliuds in a popupForum staff member Steve Pally asked how kitchen and toilet waste is handled in a popup trailer. Forum member Milt Mela explained his creative method of dealing with this issue.
I just came back from a 4,200 mile round trip with a 16' Chalet pop-up. 2 Passengers, very comfortable. Waste systems, we used a "porta john" and a modified 5 gallon plastic jug for gray water.
The translucent plastic 5 Gallon oil jug was acquired from a bakery. I cut a hole in the top of the lid and epoxied a female hose connector into the hole, I also attached a short "breather" hose. The hose from my gray water outlet is attached to the jug via the connector. The system works well, and there is no chance of the jug coming disconnected in use.
This system is nice in that it is a semi closed system - little problem with yellow jackets, leaks, and insects. We use our RV water tank for all wash water and coffee water, so it is pretty easy to monitor how much water remains in the onboard water tank plus a very easy container to carry to a rest room or other dumping station, and with a translucent tank it is very easy to see your gray water level.
