Toilet question (!)

[Marlon Brando]

Hello

We operate a challenger. Toilet service is 9 liters of blue stuff, 10 seats, but usually 2 to 4 pax. We drain our toilet water (the blue liquid) after each day because of freezing temp overnight.
But Even in summer, we drain after each day. I don't understand why because i believe it is the exact same toilet they use in construction site, or big live music event, etc. just smaller.

I believe it can last many days, if it is used only around 4/5 times a day to pi.s only, and only one time a day for the big stuff.
The chemical agent is supposed to kill the smell.

My question is :
How do you do with your planes in summer time ?
After each day as well ?

I've been promoted recently, and I'm honored to be the exclusive operating manager of toilets.

If it's been used for anything more than a pee it gets serviced. If needed more than once a day. Why? We don't want it to smell like the toilets at festivals/concerts/construction sites etc....

In our flight department and others I have been a part of, we only change blue juice only after it has been used. We also use the same winter Ops as your department. We fly Falcons and Citations.

I used the same kind of toilets in a RV, going camping with wife and kids.
I drained it only after 4 days, as per the rental agency advice.
You take the tank with you, walk 50 metres to the toilet of the gas station, and drain it over the toilet. It smells nothing at all...

It's not my money, but around here it's about 80/100€ and take some time.

Would be happy to avoid it in summer if necessary.

If you leave it in warm weather for any more than 2-3 days, the toilet will stink during every flush - this is because, unlike a vacuum system, the Challenger toilet flushes with the same stuff that has been deposited in the tank. No matter how much "blue loo" you use, you can't stop the stink!
I never passed up to opportunity to dump the lav system in the Challenger at the end of the day.

And don't forget, those tanks are made out of fiberglass. Eventually if you leave dirty bluejuice in them, the smell will get impregnated into the tank and you will not even be able to bleach it out....

We had to replace our holding tanks on our G4sp many moons ago because of this.

We have vacuum lavs on our G450 G650 and Global and we still dump the lav after every trip (ever been outside when a vacuum lav is flushed on the ground and its full ). Its cheap insurance to not have the plane smell like a farm!

Perhaps, the worst mistake in the 300 to 350 and 604 to 605 refreshes was not fitting vacuum toilets.

Try and do a little research into alternatives to the blue stuff. When I was managing an aircraft about 10 years ago I replaced the blue stuff with a clear additive to water which turned the human waste to jelly and stopped the smells. I am afraid that I can not recall what it was called. I filled up the tank with water and added a measured amount of the fluid as I was doing it. It turned the human waste to jelly which was suspended in the water and stopped smells. It also had the advantage that waste could be disposed of down the normal toilet system as it was not chemical waste.

Toilet service EVERY time it gets used whether for no. 1 or no. 2! That is the only way to keep an owner happy. And if it were my aircraft that would be the deal.
A tip.... if you can't get a service throw some ice in the pan. It works!
