Microorganisms contained in waste and wastewater can be either disease-causing organisms and decomposers. Waste and garbage into the open channel that causes a blockage and the emergence of a pool will accelerate the proliferation of microorganisms or germs that cause disease, insect and mammalian disease agents such as flies and mice.
Body of water such as rivers or the sea has the capacity of the particular decomposition. When the sewage go directly to the body of water without any treatment, then one day it may lead to environmental pollution. Pollution occurs when the decomposition of waste in the water which exceeds the capacity of water is no longer able to perform processing or decompose naturally. This condition is called septic or polluted condition that is characterized by:
- the appearance of stench
- Water color becomes dark and dense
- The number of fish and other aquatic organisms die.
