Hydroller Grey Water Tank

January 5, 2015

Discharged water from your popup camper’s sink or shower should never be allowed to simply drain out the side and onto the ground. Food particles will attract animals and soap chemicals will damage the landscape. This is particularly important in desert environments where even clean water discharge can cause erosion.

I previously used an Aqua-Tainer to collect my grey water discharge for proper disposal when done camping. The manufacturer of this container recently came out with an even better product for this application: the Hydroller.


As shown above, the Hydroller has a flip up handle that allows you to “roll” the grey water to a proper disposal location. Speaking from personal experience, this is much better than carrying 50 pounds of dirty water at the end of a camping trip. A large diameter 4″ cap makes it easy to empty and clean. It’s also slightly larger than the Aqua-Tainer (8 gallons instead of 7).

When done, simply fold the handle down as shown in the top image for easy storage inside your popup camper.

Here’s the idea in action:

The setup above is easily achieved with the following parts:

  1. 90° Drain Connector
  2. Cheap garden hose
  3. Hydroller


Simply attach the drain connector to your popup camper discharge pipe and then to the garden hose. Cut the hose to length, making sure the water drains over a nice even slope, and then discharge the hose into the Hydroller.

The Hydroller happens to fit perfectly under my popup camper (although my frame is lifted, so your height may vary).

Extra Credit:

When possible, limit your grey water discharge by using hand sanitizer instead of soap. When soap is needed, use the biodegradable camping kind to make your grey water more environmentally friendly.

And if available, use the campground dumping station. Otherwise, the campground toilet (even a vault toilet) is another good option. If you must dump it on the ground, distribute the water over a large area to avoid erosion and killing any plants with concentrated chemicals.


And finally, you might consider drilling a hole through the removable cap’s valve handle and attaching it to the Hydroller with a string. This ensures you never leave the cap at the campsite!

Any questions – please leave a comment below. Or, tell me how you’re enjoying your Hydroller!

I've been camping regularly since I was a kid, from quick Cub/Boy Scout trips to week-long backpacking trips and everything else in-between. We got a popup camper when our kids were 1 and 3 years old to enjoy more time outdoors together alongside a few conveniences like heat and running water. Since then, we've spent over 75 nights together as a family in our popup camper. I've learned a lot about the intricacies of a popup tent camper during this time and love to share those lessons here for the benefit of others.
