In the developed world, human waste usually travels through a series of sewer pipes after it is flushed down the toilet. The waste then travels to a treatment facility where the water is cleaned before being pumped back into local water reservoirs. In the developing world, many areas lack such sanitation technology; therefore, the residents use latrines or isolated areas. In these cases, the waste decomposes slowly.Continue Reading
Although the process varies from one facility to the next, most waste treatment operations clean the water by first filtering the water, then using bacteria to decompose the solids. Finally, some combination of chlorine, oxygen and ultraviolet radiation is used to kill any microorganisms that are still present. The water is then discharged into local rivers or lakes. Sometimes, farmers use the solids that were filtered from the waste water as fertilizers for their crops.
Often, waste treatment facilities must also accommodate runoff water from the roads and the “gray water” from sinks and showers. Accordingly, heavy rains can overwhelm the system, causing untreated, bacteria-laden water to enter local waterways. This damages local ecosystems and often causes local residents to become sick.
In underdeveloped regions without proper sanitation technology, people are at great risk for illness. According to LiveScience, 1.4 million children die each year as a result of untreated human waste.Learn more about Plumbing

To replace a sewer line, cut off the water supply along the line, expose and remove the old sewer line, fit in the new line, and install the vertical pipes in the wyes. Seal the fitted portion and test it out to check for leaks. Fill the trench, tamping each layer of dirt with a gas-powered tamper or by stomping on it.Full Answer >
