Where does stuff go when you flush it down the toilet?
From the toilet, your poop flows through the city's sewage system along with all the water that drains from our sinks, showers and streets. From there, it goes to a wastewater treatment plant.
The sewage treatment process
The sewerage system pumps the sewage to a treatment plant where it is processed and treated to remove any contaminants. Once treated, the resulting effluent is released back out into waterways, where it continues its journey through the water cycle.
If you live near the coast your treated sewage probably goes into the ocean. The treated sewage is cleaned to make sure that it does not cause environmental problems. This means that it should not harm the plants and fish that live in the river or ocean where it is released.
The float falls when the water level in the tank drops. The filler valve (or refill valve) sends water in two directions. Some of the water goes down the refill tube and starts refilling the tank. The rest goes through the bowl refill tube, and down the overflow tube into the bowl.
All drains lead to the ocean.
The Environment. Once the water has been discharged into a stream, river, or lake, it is treated further by naturally occurring bacteria that remove remaining organic waste. From here, water is ready to re-enter the municipal water cycle.
Unless you keep your toilet water a constant shade of blue with toilet bowl tablets, your water, after you flush, should be clean and clear. However, for some homeowners, they might start noticing that every time they flush, that clear water now appears to have a brownish or dirty tinge to it.
Your bathtub and toilet drain down separate pipes until they reach the main sewer line, which is the primary pipe to which all drains in your house lead. Eventually, all the drained materials mix and are forced out of your home through one line: the sewer main.
When shower water enters the shower drain, it combines with wastewater from the toilet and sinks then goes to either a septic tank or a wastewater treatment plant. If it goes to the septic tank, it will naturally get cleaned and allowed to seep into the ground.
In most modern houses in the US, the sink is connected to the toilet, and they drain via a joint pipe into the sewer line. In older homes, two separate lines were used, a system which is still commonly used in many rural areas so that people can reuse gray water for watering gardens and so forth.
Is toilet water reused?
Every day in the U.S., the average person uses as much as 100 gallons of water. Flushing toilets and taking showers and baths are two of the biggest culprits. All of that wastewater that's being flushed or drained into septic tanks or sewers can be recycled. People aren't often comfortable with that idea.
When a conventional toilet is flushed, water from the tank rushes into the bowl through an orifice called the flush valve. Before you trip the lever, this valve is plugged with a rubber stopper, called a tank ball, flush valve seat ball, or the newer, more effective flapper or flapper ball.

Leaving pee in the bowl instead of flushing it away seems gross and unsanitary to some. However, the science says that flushing every time actually spreads more germs. Yup. Meet 'toilet plume' – the spray caused by that blast of water when flushing.
Cleaning your private parts after peeing is an important part of overall hygiene. It helps get rid of odors caused by leftover urine droplets and keeps your genitals healthy. Bacteria need warmth and moisture to grow, so keeping the area clean reduces the risk of skin irritation and bladder and yeast infections.
Common reasons your toilets to keep backing up are: There's not enough water in the tank. There's a clog in the drain line. The main line for the house is clogged.
Around the world, untreated sewage flows into coastal waters, carrying organic waste and nutrients that can lead to oxygen depletion, as well as disease-causing bacteria and parasites that require closing beaches and shellfish beds §.
The Ocean Dumping Ban Act of 1988 amended the MPRSA and now prohibits the ocean dumping of municipal sewage sludge and industrial wastes, such as wastes from plastics and pharmaceutical manufacturing plants and from petrochemical refineries. The 1988 amendment also banned the ocean disposal of “medical waste.”
Most sewage finds its way into the ocean as either poorly treated or untreated discharge, or as stormwater runoff. In places with little to no infrastructure, like the developing world, the majority of wastewater goes untreated.
Areas in Australia, Singapore, southern states of America – like California and Texas – and Namibia all make use of wastewater recycling facilities to help provide their population's drinking water.
After the microorganisms have absorbed and digested the organic materials, the wastewater is sent into secondary sedimentation tanks. In most situations, secondary treatment must be followed by a disinfection process to kill harmful pathogens (protozoa, bacteria and viruses).
Can sewage water be treated for drinking?
The answer is yes. Various treatment systems are available, and they allow you to use sewage water as potable water. In fact, there are multiple states where freshwater comes from sewage water. So, while you must avoid untreated sewage water, they are suitable for drinking once they get treated.
"The toilet water is usually cleaner with regard to bacteria because toilets get continuously flushed, whereas a water fountain is left open to the environment," said Dr. Phillip Tierno of New York University Medical Center.
More Bacteria Comes From Tap Water Than Flushing the Toilet, Study Shows. But the good news is that not all bacteria is bad. File this under one less thing we have to worry about: The amount of airborne bacteria that comes from a toilet flush pales in comparison to the microscopic stuff flowing in from the faucet.
Closing the lid when you flush is a good habit to get into.
Closing the lid before flushing can definitely curb the spread of some aerosolized microbes that would otherwise be sprinkled throughout the bathroom, says Marilyn Roberts, Ph.
You see, every drain in your home is connected to a pipe that moves used water from your house to a sewer in the street; that's right, every toilet, shower, sink, washing machine, dishwasher, and anything else that uses water connects to one singular pipe.
The general answer is that the showers and toilets can use the same drain, but they should not be sharing the same waste trap arm. There are other factors to consider as well, such as whether your drains lead to the main sewer line, or if there are septic tanks that are used in your city or town.
Are Toilet Pipes Connected To The Shower? No, the toilet pipes aren't directly connected to the shower drain pipes. The toilet has its own drain pipes that connect to the main drain line. The same applies to the shower drain line – it eventually connects to the main drain line.
A full bath can use up to 50 gallons of water . Using these numbers, a shower will use less water in most cases. This doesn't mean that you need to cut out your bubble baths completely, but maybe take them sparingly in order to save water. When you do take a bath, try to only fill the tub up part way.
This isn't uncommon. Your washing machine might have been placed in between your toilet and sewer stack. * If your toilet and washing machine drains are connected, they have the same venting system. This can cause your toilet to gurgle when your washer drains.
Kitchen tap water supply
The tap water supply enters the kitchen with an indirect system from the stopcock valve located outside or underneath the sink. The kitchen sink comes directly from the mains, but bathroom water is stored. In a direct system, fresh mains standard water is sent directly to every tap in the home.
When I flush the toilet water comes out of the tub?
The most common reason for sewage coming up through your bathtub is a clogged sewer line. All the sinks, toilets, and tubs connect to a single drain pipe that leads to the sewer line under your house. This drain line carries all wastewater and sewage away from your home to the city's sewer system.
All water coming into your house comes from the same single source, so unless you have two separate storage tanks for your kitchen taps and bathroom taps (highly unlikely) then the water will be identical.
So it might appear that our planet may one day run out of water. Fortunately, that is not the case. Earth contains huge quantities of water in its oceans, lakes, rivers, the atmosphere, and believe it or not, in the rocks of the inner Earth.
Tap water is recycled pee. When sewage is treated, the water that is produced is called effluent. Effluent contains nitrogen and phosphorus, which are nutrients that plants need to grow. Effluent is often used to irrigate crops.
Depending on the number of bacteria in the water, things could get way more serious. You could poison your blood, leading to a massive inflammatory immune response known as sepsis. It happens when your body tries to fight against infection. And it can be fatal.
Since commercial buildings have more floors, more bathrooms, and more toilets in those bathrooms, they naturally have a more complex plumbing system. Because so many people use them day in and day out, they are built to handle a high number of flushes and high levels of pressure.
This hole is known as the siphon jet. It releases most of the water directly into the siphon tube. Because all of the water in the bowl enters the tank in about three seconds, it is enough to fill and activate the siphon effect, and all of the water and waste in the bowl is sucked out.
Your local Clearwater plumber assures homeowners that water from the toilet bowl cannot back up into the tank; water in the tank is just as clean as water from a faucet. If you clean the bowl and flush several times, even the water in the bowl will be clean.
Many large, solid objects flushed down toilets can damage plumbing and get stuck in pipes. This leads to expensive repairs and replacements for property owners. To keep your local water supply clean and protect your plumbing from unwanted damages, it's vital that you flush only permissible items down the toilet.
Taking the wastewater away
Whenever you flush the toilet or empty the sink, the wastewater goes down the drain and into a pipe, which takes it to a larger sewer pipe under the road. The sewer then joins our network of other sewers and takes the wastewater to a sewage treatment works.
Can stuff come back up the toilet?
Often, if you have a toilet backing up, it is because your local drain line is compacted with extra thick toilet paper, sanitary products, wipes, or even paper towels. This can result in water backing up into your toilet, causing an overflow.
Similar to dental floss, sending hair down the drain can cause larger problems later on, experts at American Water note. Hair tends to stick to the inside of pipes, leading to build-up and clogs over time. Don't flush large clumps of hair down the toilet, and use drain covers to protect your shower and sink drains.
Most modern toilets in today's homes are cleaned on a regular basis, flushed right after use, and filled with fresh water (free of most contaminants).
Far too often, if you drop your toothbrush, it will land in your toilet bowl. Obviously, you can get a new toothbrush, but you cannot simply flush the old one down the drain -- you must remove it.
If the recycled water is intended for human consumption, the next stage is to put it through further treatment before mixing it with natural water supplies. However, sewage water which has gone through wastewater treatment forms 'recycled water' which is clean enough for some agricultural and industrial usage.
Usually, yes. The vacuum toilet used on planes, patented by James Kemper in 1975, sucks the waste into a holding tank where it is stored until the plane lands on the ground.
Common reasons your toilets to keep backing up are: There's not enough water in the tank. There's a clog in the drain line. The main line for the house is clogged.
