While staying at our Washington home in previous years, we were careful to avoid filling our gray and black waste tanks, since we didn’t have a way to empty them until after we left; we used a bathroom in the house instead of in our coach.

This time, we were staying longer, but we also had new tools available: we had purchased a waste tote tank, and a macerator pump. I used both while staying this time.

The house has a septic system in the backyard, with inspection/cleanout ports:

I initially drained the waste tanks into my tote:

I then pulled the tote around the back using the handle (not too difficult with the steerable front wheels), and drained it into the septic system:

Using the other port to drain the last liquid out of the tote:

That was pretty easy. But then I tried a different approach. I bought two 100 foot hoses (that will only be used for this purpose, left in our shed), and used my macerator to mash up and pump the waste through the hoses directly into the septic system:

I plugged the power cord into the electrical outlet in the wet bay, via a plug-in switch:

A power supply, to convert the 110V to a 12V car-style connector (there is a switch after the power supply, but the power supply has a fan that runs as long it has power, hence my plug-in switch):

(Hmm, there is 12V power for a light in the wet bay, so I could hook up a connector to that… nah, probably not worth it for this occasional use.)

A closer look at the macerator, connected to my sewer hose closure and the hose:

200 feet of hose going around the house:

The end of the hose into the septic system:

Taking a peek; it isn’t a high flow, so takes longer than usual, but is much easier than using the tote:

I removed the hose and re-sealed the inspection plate when done each time, to avoid smells getting out or animals getting into the septic system. If we were to ever do this longer-term, we could no doubt devise some sort of gasket or port to let the hose remain hooked up in a sealed way, though it really wasn’t a huge hassle.

With the 50 amp electrical hookup, a water hookup, and these waste solutions, we are able to stay home as long as we like.
