Survey for Uni Project on Marine Toilets

I just tried your survey, and I think it will give you misleading results.
I have already replaced my seatoilet ( no tank) with a chemical toilet I discharge ashore. That is as green as I can be, avoiding marina and coastal pollution.

So now if I answer your questions honestly I say I will not consider replacing it and so would give it a nil budget.

That would put me with the don't care camp, which is untrue.

Also once a button has been clicked it cannot be undone and left unanswered, you have to choose from the options, so it becomes impossible to not answer any of the questions when none of the options are valid. This will give you false results.

Finally there is no scope for comment except here.
 
I have a lot in common with my toilet.
I put up with a lot of crap from a number of people on quite regular basis, which causes me to get really browned off. /forums/images/graemlins/laugh.gif /forums/images/graemlins/laugh.gif /forums/images/graemlins/laugh.gif /forums/images/graemlins/laugh.gif
 
While sea toilet use in harbours, rivers & marinas may lead to an accumulation of detrious I can't help thinking that shrimps, crabs, cockles & mussels in fast flowing tidal areas will deal with quite a lot of waste.

Have you any evidence of problems known to be caused by the use of sea toilets in open waters?

I eat a lot of self caught sea food in the summer when there is a lot of sailing activity in the area & not had a problem yet. Am I just lucky, or is the threat being overstated "for environmental reasons?" Fear is often seen as a great motivator.

People seem to ignore the fact that fish, dolphins etc and birds crap in the water all the time. Dogs crap along the waters edge.
Prawns are underwater cockroaches and live on rotting matter.

Of course its always a little unpleasant when someone's turd floats into view. /forums/images/graemlins/blush.gif
 
Isn't Academia a wonderful place? All a part of the great Dumbing-down exercise. This is how La creme de la creme wll be able to lead the World. Those with a School Cert 60 years ago had a better all-round education than many graduates today - not their fault - no wonder there is a move to introduce the Baccalauriate to our educational system
 
My understanding is that the Bac is already an option, but the schools choose not to take it as it stands... might be wrong though...
 
Is that how you spell baccalaureate?

To the original poster, filled in the survey, the subtext would seem to be that sewage discharge from recreational boats is an environmental problem. Has any research been done to validate this position?
 
A tea bag takes longer to decompose and causes (according to a YM article by Tom Cunliffe on sailing and being green) more pollution than small amounts of digested fecal matter.

I think that Atlantic College in South Wales was been using the Bac for a long time.

And they have (or had, not sure how up to date this info is, got from wiki) their own RNLI station.

The College is unique in having an active RNLI Lifeboat Station within its grounds, and its Atlantic 75 class boat is manned by staff and students from the College.

I think the Survey is to find out whether there is a market for manufacturing holding tanks.

Many years ago I did some work for a water firm on a sewage farm. I saw big pile of what was dried up (poo) funny didn't smell at all. I asked the chap how a sewage farm works.
Well all we do is filter the stuff. How said I? We pop it all into a large tank what floats to the top we scoop of put it in a pile. then we put it through a filter and what is in the filter we scoop off then we put it through an ozone filter to kill a couple of bugs. Then I said. He said we put the stuff back in the river.

Well what do you do with the lumpy bits? Ahh we take them to a land fill. But I said if it is just poop can you not put it on the land. Defiantly not he said. You see it not the poop that is the problem. It just that what you see there is highly toxic chemical waste from industry and sanitary products as well as poop and we have no way of removing it. If it was just poop we would never need to use fertilizer ever again. (quote bio chemist, sewage works Severn Trent water)

He also said there are equations for the safe limit of quantity of poop that can be put back into the rivers dependant on the flow of the river so as not to disturb the eco system.

So from that. Human waste is fine in small quantities in fact beneficial as long as you don't use bleach to clean your loo (ha ha). One crap from a boat every so often is not going to damage our environment. As for a marina just use the loos ashore. As they reckon it takes tens of years for the water to refresh itself and who wants all that poop floating around your nice white hull.

I will not buy a holding tank because the whole thing is based on hysteria and environmental clap trap. If boat bogs where doing any damage to the environment then something would have been done twenty years ago when they were fully aware of it. After all they started the Thames clean up twenty years ago and still they put small amounts of sewage in it a dam sight more than any boater could over a life time. ermmm they have the very rare sea horse in the thames now.


Rant over. Hope its food for thought.

And why do you think it is called an Atlantic class????????

They had theirs before the RNLI !!!!!!!
 
Thank you to everyone that has taken the survey.
It is for a side project I am doing as there can be an impact on algae growth and oxygen levels in the water caused by discharges from recreational boat users. particularly in low flushing areas where water circulates only slowly.
Not a major problem compared to the water companies sewage discharges but worth thinking about.
thanks
