Well, since this thread IS about toilets, why NOT just talk out of your ass?

It's amazing. Every other animal sh!ts in the woods (and every sea creature sh!ts in the ocean), and it's considered natural. But GAWD FORBID if humans sh!t in the woods.

Except people flush paper, chemicals, condoms, tampons, and god knows when else down their drain.

Water is cheap. My water bill is $11 a month. That's nothing.

You'd have to desalinate the sewage anyway, or dump it straight back into the ocean, and I don't think most of these people living near the coast want raw sewage floating at the beach.

Good point, getting rid of the saltwater would be difficult. Could we just bring it out further into the ocean and dump it? I think the oceans are big enough to handle our waste without causing any serious problems.

Yeah, but they throw trash pick-up and storm water on mine which makes the total bill $60.

We are going to have a desalination plant here in Brevard county fl. the population has exploded and 25% of the land area is covered *according to stats* so the water doesn't get back into the ground but runs off into rivers, ocean, ect. That is the claimed reason for the desalination plant anyways. The big debate is over what to do with the huge amount of salt which would fill over 400 dump trucks each day. They want to put it right back into the lagoon , but the enviromental impact will be terrible so it is a big fight.

Guess most people in here don't realize that at least in the Northeast that the Sewage Treatment facitlities up and down the coast have pipes that go out about 3 miles into the Ocean and that is where the sewage is released.

I had a reply to this but I accidentally typed the s word. Then I wrote another reply and had the s word again! The forum in its infinite wisdom, instead of censoring my bad words, DELETED MY WHOLE POST.

Your close to the reason... except in places like Atlantic City, they already dump sewage in the ocean. One of the reasons I don't go to the beach.

 

[FoBoT]

ships use salt water for toilet water, because the sewage is just pumped right overboard anyway, no reason to use potable water (that has to be distilled from sea water to begin with)

land based facillity is much different situation

 

[SuperTool]

my sh!t is too good for salt water.

 

[NiKeFiDO]

the private companies that provide the water (not sure how much gov. control there is for water systems) have no profit motive to do it. it wont be done. sorry.

The amount of human waste generated in this country would have you up to your knees in sh!t if everyone was doing it in the woods. The US currently has a few deep sea sewage injection systems. The one I'm familiar with in San Diego dumps 400million gallons a day of partially treated raw sewage 3 miles out into the ocean.

Originally the pipeline was only a half or mile or so and they extended it after raw sewage began washing up on the beaches. But the problem remains that we are dumping a MASSIVE quantity of organics and pathogens into the ocean although the San Diego authority does a very good job removing a large quantity of those organics with their primary treatment there have been large algal blooms that have killed milions of fish. These mobile clouds of organics turn into huge clouds of death as algae blooms into the cloud and sucks all the oxygen out of the water.

Every year the organics discharged into the gulf of mexico are causing a red algal bloom called the red tide. These events are killing more and more marine life every year.

Consider for a moment how dangerous human waste is, not only is the vast quantity of highly enriched organic material causing big algae blooms in the ocean they kill all sea life that enters them and the pathogens we are putting into the ocean have the possibility to work themselves back into the fish and other marine life we eat.

So the next time you eat fish wonder if maybe that fish was exposed to human hepatitis or other serious pathogens from sewage.

It would make more sense to utilize composting toilet or recycle the water by filtering or chemical treatment for domestic waste disposal. Also, greywater (sink, bath, dish, and washers) can be use to water the garden & lawn instead of pumping it directly into the sewer.

Composting toilets, University of British Columbia

I agree :thumbsup:

Where do you think the millions of people in the Navy / cruise ships / personal boats dump their crap? As soon as your 12 miles out - it gets pumped overboard

We were discussing water usage in my Environmental Science class today and in an average household toilets use the most water. Even more than showers. So why don't we use salt water for the toilets, at least for people near the coast? It would save a lot of fresh water. Would it still be more expensive in the long run? How about nonpotable recycled water?

The cruse ship I was on last summer filled their pools and spas with the salt water from the ocean.

How you gunna get nonpotable water into homes?

 

[0roo0roo]

as said, piping system required would be so extensive and require so much money to build because of the digging/disruption of already finished buildings/roads that it would never pay itself off.

What he said. I cry every summer when the flesh eating bacteria and fish kills keep me away from the Gulf Coast.

putting the pipe far into the ocean floor requires pumping the sewage.

pumping = energy

My dog wouldn't go for that idea, he'd have a real unhapply face after he tried it out

???? Do you mean it would require pumping to bring salt water to the home or are you saying that gravity fed deep sewage lines require pumping because the first one is true but the second one is not.

both.

we were talking about that in thermodynamics (dumping hot water from power plants into the ocean floor 5 miles away from the shore).

you need to build a big long pipe line, and you'll need a big pump to overcome the static pressure from the weight of the water from the ocean.

same thing applies, why would you want to pump sewage anyway?

That is incorrect, a gravity fed line that has a reservior surface above mean sea level will have sufficient head at the discharge point to exceed that of the static water pressure allowing a constant flow rate equal to the input rate. For evidence I submit the following:

http://www.sandiego.gov/mwwd/facilities/ptloma.shtml

The Point Loma Ocean Outfall was built in 1963 for the discharge of treated wastewater into the ocean. In 1993, the Outfall was extended from a length of two miles off the coast of Point Loma to its present length of 4.5 miles. Twelve feet in diameter and operating via gravity-feed, the Outfall ends 320 feet below the surface in a Y-shaped diffuser to ensure wide dispersal of effluent into ocean waters.

Don't worry, I'm not supprised that a thermodynamics professor has a false understanding of basic fluid dynamics and gravity feed issues.
