What is Sewage ?

Sewage is the wastewater generated from various utilities in our homes and includes kitchen, laundry and bathroom sink, as well as what you flush down the toilet. It is essentially 99.7% water containing solids like food particles, oils, dirt and chemicals like detergents 0.03%. Dirty water from businesses and factories is also discharged into the Sewage Treatment system. This is known as trade waste. Most of the sewage from our homes and businesses flows via large underground sewer pipes to Sewage Treatment Plants, where it is treated to make it safe for release back into the environment.
Sewage usually carries pathogenic organismss that can transmit diseases to humans and other animals; contain organic matter that cause odor and nuisance problems; hold nutrients that may cause eutrophication of receiving water bodies; and can lead to eco-toxicity. Proper collection and safe, nuisance-free disposal of the liquid wastes of a community are legally recognized as a necessity in an urbanized, industrialized society. The reality is, however, that around 90% of wastewater produced globally remains untreated, causing widespread water pollution, especially in low-income countries.

Increasingly, agriculture is using untreated wastewater for irrigation. Cities provide lucrative markets for fresh farm produce. Agriculture has to compete for increasingly scarce water resources with industry and municipal users. Often there is no alternative for farmers but to use water polluted with urban waste, including sewage, directly to water their crops. There can be significant health hazards related to using water loaded with pathogens in this way, especially if people eat raw vegetables that have been irrigated and grown with polluted water / sewage.
