No, you should have no marine toilet whatsoever in order to protect the
environment. You should just hold it until you get back, or better yet, don't boat in "our swimming pool" as you put it. -- Keith __ A husband is what is left of a man after the nerve is extracted.

It is expensive and needs space, but in case of failure of msd the tank can save the day. Paolo |

I believe Paolo's concerns are valid and his queries sincere. While it may be counter-productive to be obsessive on these topics, I believe that it is helpful that we as sailors consider clearly our options in regards to waste disposal and power management. Part of the attraction to sailing as a lifestyle is that it is relatively easy on the environment, as opposed to, say, driving a Hummer to Mexico. The continuing interest in marine heads, composting, windvane and wind turbines, solar panels, electric and/or fuel cell diesel replacements, and so on reflects a concern not only for energy "independence" to extend cruising, but also a desire to "sail lightly upon the earth (or sea, I suppose)". If forums like this can educate or elaborate on the options available, all to the good. Sarcasm, I find, is less helpful, unless it is directed at trolls. R. |

Don't forget ducks, seagulls, etc. To add a little more confusion to the marine water pollution arguments, the journal SCIENCE (29 Mar. 2002) reported on a study which tracked the biological sources of fecal bacterial in Virginia watersheds. Only 15% of E. coli bacteria had a human origin (i.e. septic runoff and boat discharge). The remainder came from other animal hosts, the largest contributor being waterfowl with 32.5% of the total. Similar studies are being carried out in California, Washington, and Oregon. Whats next? Diapers for geese? What about whales and everything else in the ocean? Who's gonna change them? What is absolutely mind boggling is that there are people who worry about that stuff. Anally fixated neurotic paranoia is as sick to the mind as cholera is to the gut. Get used to the idea that the top 3 feet of this entire planet is covered in ****. It is what soil is. Fish ****, bird ****, mammal **** are all good for you, essential ecological nutrients. When you eat, what passes through is just not needed or used by your G.I. tract, it is mainly inert, it is not inherently dangerous, unless the "donor" is ill with a *pathological* bacterial infestation, or worms or something. In which case, the afflicted individual might know and in this day and age, should have emergency public health assistance easily available, for the betterment of all of the rest of us. That is what taxation and public health is supposed to be all about. Public toilets are a big issue right now in China, where the olympics are bound. Where does a homeless person go in Noo Yak? Or is it better to chase the sickos out into the countryside, so they can die discreetly and fester quietly in a ditch somewhere, hopefully not too near where the peasants grow our food or draw our water? Perhaps some of America's tax slaved military might could be usefully employed tracking larger sea animals and bombing their fecal trails with DDT or something? They could contract to get rid of this offensive chemical. It is suggested you should take care to ensure that your servants, close aquaintances and intimate friends are healthy in mind and body. Beyond that, get over it. Poo is good for you. War is dirty, a stupid waste designed to enrich arms dealers alone. Fuel is a weapon. Terry K |

Hi, Y'all,
Truncating this to a question or two: "Peggie Hall" wrote in message ... Any manual marine toilet that's working anywhere near factory specs can move bowl contents at least 6' in the dry mode...so if you learn how to flush your toilet correctly, there shouldn't be any water or waste in the line between the toilet and top of the loop to run back down into the bowl. This has me very curious. You're saying that enough speed/pressure/whatever-moves-it is developed, in an anti-siphon environment (the vented loop), that I can clear a 1.5" line for what is (in the new installation) about 3.5-4 feet (to the top of the loop) by dry flushing? I buy that I might be able to flush solids, with water, that far, if I'm aggressive enough with my volume (and the Raritans we have probably put in a cup per stroke or so), but I don't see how that pipe can empty, dry pump or not. I'd have to think the surface tension of the water would not be sufficient to prevent the water running past the bubble at the edges, as you recharge between strokes. I'd be thrilled to think I could really empty it, as that - with a straight discharge - would go a long way to keep odor down (should be only sea water to make odor, that way). Help me out with my physics, here? On the subject of joints, I'm of distinctly curious mind. While my current home isn't this way, my prior home had hundreds of feet of PVC pipe run, with all the necessary ells, Ts and other fittings, all successfully carrying high pressure hot and cold water.... Am I missing something? What you're missing is: houses stay put...they don't get tossed around by wind and wave. Boats do. Well, yes, of course. But if I secure a large pipe, in a short run, under next to no pressure, it's not going to move. In the house example, you could see the distortion of the hot water pipe from expansion vs resting state as hot water entered, and see it jump as the water was shut off and turned on - but it all stayed together. In the boat, we'll use hose as movement absorbers. Not trying to be argumentative - just understand why I shouldn't be doing as SeaLand recommends...

You aven't got my point: disregarding the legal point or even the chemical
pollution, the soap can be safe and not chemically polluttant (maybe...) But you can guarantee that the oil (only to remain with your example...) that the soap as removed is also safe and not polluttant? No...soap or detergent is safe, and so is anything that goes down a sink or shower drain. But there is no soap, detergent or other cleaning product that can transform a pollutant--say, oil in a bilge--into an environmentally friendly product. Which is why it's such a mystery to me that boat owners are so concerned about organic matter in gray water or treated toilet waste, but give no thought at all to what their bilge pumps are discharging. And even if it is safe, do you tink that a place full of soap bubbles and oil and watermelon seeds floating around is nice place where to send the boys to swim? Don't confuse galley WATER with galley waste (garbage)--which is what watermelon seeds are. As for any oils (cooking or body), they're emulsified by detergents and soaps...and most of those are very low suds these days. You're far more likely to see suds and bubbles around a boat being washed than from any sink drains. If you're really sincere about protecting the ocean environment, concentrate your efforts on keeping oil and grease out of the bilges instead of worrying about what goes down a drain. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://69.20.93.241/store/customer/p...40&cat=&page=1 http://shop.sailboatowners.com/detai...=400&group=327 |

Yes, Skip...that's what I'm saying. A siphon break (vented loop) has no impact on water being pushed through it...it only allows air into the line to break the flow of water being pulled through it.

Apparently my arguments have stirred up the group intollerance.
If you agree I would restart the MSD discussion in a different thread and reformulate it. I am really interested... You aven't got my point: disregarding the legal point or even the chemical pollution, the soap can be safe and not chemically polluttant (maybe...) But you can guarantee that the oil (only to remain with your example...) that the soap as removed is also safe and not polluttant?

Which is why it's such a mystery to me that boat owners are so concerned about organic matter in gray water or treated toilet waste, but give no thought at all to what their bilge pumps are discharging. I am interested only in small sailboat, i am building one 26' catamaran. The only oil that you can extract from my bilge will be olive oil... :-) And even if it is safe, do you tink that a place full of soap bubbles and oil and watermelon seeds floating around is nice place where to send the boys to swim? Don't confuse galley WATER with galley waste (garbage)--which is what watermelon seeds are. As for any oils (cooking or body), they're emulsified by detergents and soaps...and most of those are very low suds these days. You're far more likely to see suds and bubbles around a boat being washed than from any sink drains. I have trouble with the language, I don't explain clearly my mind. The watermellon seed is only one example of what can transform a clean peacefull place into something unpleasant, disgusting... I try with another example: if the bottom is mud, a small movement transform the water from cristal clear to something dark and unpleasant... it is safe, but I don't like it. In the same way the boat discarge: head, galley, ad bilge water can be safe, but doubtless aren't "cristal clear"... If you're really sincere about protecting the ocean environment, concentrate your efforts on keeping oil and grease out of the bilges instead of worrying about what goes down a drain. I agree: my engine is wind. But sometimes the actions have a "flag" value: over my roof I have photovoltaic panels, I do know that the energy balance (amount of energy used to produce the cell/ amount of energy generated in the life) of photovoltaic cells is largely debatable and my photovoltaic panels don't change my country energy balance... But I have put my money there because I want a greater attention to this type of problems. Paolo |

So why doesn't Southern California allow Electra-San treated discharge??
Everett Long Beach, CA "Peggie Hall" wrote in message ... Paolo Zini wrote: ...CUT... removing it altogether...why store waste aboard if you can discharge it legally AND with far less negative environmental impact than dumping a tank? just curious... Do you like to swim in your s**t? Every sewage treatment plant in the world discharges into somebody's waters...so it's just a matter of how well treated you want it to be. And fwiw, the negative impact from just ONE dumped holding tank is greater on the surrounding waters than that from 1000 boats, all using Lectra/Sans, in the same waters for 24 hours. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://69.20.93.241/store/customer/p...40&cat=&page=1 |

Oops, sorry. It's illegal to discharge even olive oil...
