Emptying Macerator Tank Black Waste

[Coastal Cruiser.]

I would have assumed that a drive over waste point was for both black and grey or was there a big sign that said "grey only", I bet it all went to the same sewer.

Nothing saying what it was Martin, i asked the lady in the reception and she said grey only.
As we know grey waste is classed the same as black and should be discharded down the sewer or taken awa.
Probably no reason why i could not have dumped there and if i open grey and black together you woud not be able to see any different.

I know a lot put grey in the bushes but under current regulations it must be discharged into a sewer system.

 

[Mr porky]

Unless it states not to I would use a grey drive over to drop black as it’s foul waste and should be going into a sewerage system.

You have to ask if the black can be dumped over a grey waste grate, On some parks it goes to different destinations. Its about chemical. A treatment plant will not take toilet chemical. The benefit of a black tank and macerator is no need for chemical so can be dumped into treatment plants. Yes its pungent but if my memory serves me correct even with chemical its stinks, no getting round that. The main thing is to check is where it's going. I know of some parks where the grey waste goes to a burn or brook. With my blank tank I carry a cassette I had spare with my old MH and decant into that on the very very are occasion I need to.

Lots of grating are for grey only not because of sewage arrangements, but because the black waste soils the gratings with stubborn turds and toilet paper.

Grey only gratings are common as the vast majority of European motorhomes have grey waste tanks, but cassettes for toilets. Situation in USA very different.

I use Ammovit in my black tank, no lumps or paper it dissolves the lot

We never have issues with paper as we buy a cheap brand which works with a macerator very well.

 

[Mr porky]

I’m sure an another thread a while back a fellow funster pointed out that if its grey waste it should not be going into a soak away anyway.
foul is foul wether it’s from a toilet or a shower.

It is much nicer post macerator. However, not all systems use a macerator. Most RVs would only macerate when pumping long distances, but would drop it unchopped into a grate.

I think most modern European vans macerate into the holding tank, some older ones might be different, with the addition of ammovit ours is just black water and the grey smells much worse.

So, just collected the moho from hab check etc. Been there since November because we went into lockdown.

had the seals el gauges fitted and delighted with them so far. Seem very accurate

Besides C&CC, are there other reliable ways of finding drive-over waste disposal sites in the UK?

We have a short hose, but no pump, and I think we're going to be spending more time in the UK than we expected this year.

 

[BillyKontiki]

Never had a problem in the uk or on the continent.
However we have extended the pitiful 1m hose to a 12 metre hose.

Is that not a bummer to keep clean

That is definitely the issue. It is why I would like to pool some knowledge and pop them in a map. For example I have been to a CL with a ground level emptying point and there must be quite a few.

As a user of Black tank and grey tank, system, for 5 years with current M/home and for 10 years with previous M/home
The concept of taking your S.. home with you its the perfect solution, You dont rely on somebody else water to clean your cassset, or anyone else facilities to empty it,
The chemical and sewerage plant argument, There are two points, the modern day stuff, (last 10 years) for black tanks is not a chemical rather crap loving bacteria, The only stuff from my black tank is non smelly liquid, The second point is think about what you clean your toilet with at home it goes to the same place. I have found the mess on the dump grids in Europe come from cassettes owners who could,nt wait and dont hose it off with the supplied water.

Now it is upto the individual land owners but the rule is now, unless the water came out of the sky, all other goes down the same pipes. Its very simple now, clean water is surface water, black and grey, is dirty water.
Funflair and others are correct, the grey has far more smell to it than the black that comes from my tank.
Because water is a precious commodity these days, the new macerater toilet for M/homes uses grey water to flush so you will see the option now for very large black tanks and a much smaller grey, as its reused

Sorry its a bit long, But the point is for Motorhomes "Take it home"

 

[Midnightflyer]

Had a macerator toilet for the past four years, it washes away with the grey waste. Sites in Spain where we stay have no objection always check first.

Using grey for flushing and a bigger black tank sounds like a good idea. Hasn’t heard of that.
might be a little concerned that the system could clog if it was greasy. Too late for me. As black and grey are separate

 

[John Russell]

As accessible ground level dump points don't seem to be that common in the UK, maybe Jim could consider adding a section to the Local Guide areas for the UK?

We used black/grey tank for several years----- I am devastated now that we are down to a single cassette ( nowhere to carry a second!!)
Such a huge retrograde step in my opinion
I assume the modern black tanks can discharge via macerator/ pump??
We used to carry a length of large dia light flexi hose in the rear step accross back--- a short piece to connect directly to a dump tank ( via a 3"? bayonet fitting) ----we rarely needed to use this and it lived on the roof.
Then we had a macerator with bayonet fitting onto dump valve---- the discharge pipe screwed onto this 3/4"i think?------a standard RV water filling pipe fitted on this thread---- each length is something like 30' and all had male/ female threads--- I used to carry four of these so could use whatever was required----usually only one.
I NEVER assumed a grid was for black!!!----- there is usually a separate point for black.
After dumping black we always flushed through with grey even if it meant putting grey into black waste point------ we never flushed the system with fresh water so it was far better than using cassettes and rinsing several times IMHO.
Our black tanked motorhomes have gone but the complete system lives on in our Portuguese off grid cabin---- and until the macerator dies that's how it will stay!!!!!.

Not at all as we empty the black first then we empty the grey.

 

[Martyn911]

Yes - another toilet thread! Enjoy .

I'm toying with the idea of a MH with a macerator and large black waste tank. Just how difficult is it to find places to empty the tank both on and off campsites, UK and abroad?

Had Concorde motorhomes since 2004 with black tanks, not a problem in Europe. In the UK I decant into a reservoir roll tank.

I Too have a " Concorde" with separate waste tanks .For the 'black' tank with macerator i use bio-Washing machine pods .The effluent on discharge only smells of washing fluid waste ,not unpleasant at all. The Grey tank then follows ,to rinse the grating/manhole etc. The convoluted 'drain off hose' if used ,is easily washed through giving it a twisting 'swirl' before storage again. I prefer this system to the objectional and smelly and limited content of the removeable cassettes .

Do you put the pods into the toilet, it doesn’t affect the internal mechanisms of the macerator ?

Which reservoir roll tank do you have? I have been looking for something which will accept my 3 inch hose

 

[Sundowners]

I see the writing didn't come with the pic-------
It is fiama---- 30 litre I think ?
Ours has a level gauge but I can't see one on this one


This is what we have with a bayonet fitting to suit our dump hose ( just a short piece enough for the job as using the long slinky can be messy)

 

[pelican]

Works OK as long as you can get your van close enough so the hose will reach. Many CLs etc have disposal points behind a a hedge or in a place you cannot get near with the van. You will then need a container you can decant into and then empty out. Basically if you are not on a large campsite you are still effectively emptying a cassette.

Where do you keep the pipe!

Thanks. Looks just the job Will see if I can get one

 

[ceejayt]

They have a new 30litre one plus an add on pice for hooking at their end. Ordered both. Thanks for the pointer

I put the 'pods' in & flush as & when depending on the overall use ,maybe every other use. Not affected so far as i know ,Everything works O.K ,seals O.K .

Had a bit of a dissagreement a while back when someone said you are allowed put grey waste down a road gully.
40 years of major construction works and ive never

These do a good selection.
