Have you ever wondered how waste water is managed for uban homes? We recently posted an article about septic tanks for rural homes but did you know urban homes do not have septic tanks? We specialize in septic tank installation and so we don't do a lot of waste water work with urban households because they don't have septic tanks.
The reason whey urban households don't have septic tanks is due to the congestion. Houses are a lot closer together and so there isn't room to put a septic tank in the ground. It would be difficult to put a sewage system in a small area and thus there is a different solution. Urban houses have separate waste lines that connect to the municipal waste water system. The sewage and sullage is collected into this sytem and it flows off of the property and heads for a treatement plant.
Sewage treatment plants are in charge of treating all the waste water that comes from the urban households. The solid waste is removed in the treatment plant and then the water is transitioned to a land fill and dumped into remote areas back into the soil. This water is sometimes used for irration puposes or fed into rivers.
Urban buildings can sometimes be big apartment buildings or shopping malls with large amounts of waste water being produced. These types of locations typically have waste piping that will feed the waste water into a sewage treatement plant as well. It is common for waste water piping to separate solid waste water from non solid waste water. Solid waste water is sometimes called "black-water" and non solid waste water is referred to as "grey-water." If they are able to be separated out then this helps a septic waste plant process the water more efficiently instead of running all of the volume through the whole system. Water processed through a septic plant takes time and thus we want to make sure we are only putting the necessary loads on the system.
We will have to discuss the details of a water treatment plant in another article and go into the details of how it all works. It is interesting to learn more about waste water and where it goes and what happens to it after it flushed down the drain. When you don't know what happens to the waste water you simpley flush a toilet and then have no idea how it actually works. We think it is better for people to know how systems work in their homes to have a better understanding and respect for how much work goes into making life simple and less stressful. Our waste water systems have been improving more and more as time goes on and even though they are simple in process we always have more we can learn about what is best practice for us as humans and what is best practice for our world. Keep learning more and more and remember that if you live in an urban area you have a different waste water system than those who live in rural areas.
