Sewage Treatment
The process of removing pollutants and contaminants from wastewater generated by households and industries. Sewage treatment involves physical, chemical and biological processes designed to clean contaminated water.
Municipal Sewage: Wastes (mostly liquid) originating from a community; may be composed of domestic waste waters and/or industrial waste waters.

Septic Tank: sewage disposal tank in which a continuous flow of waste material is decomposed by anaerobic (in the absence of oxygen) bacteria.
Chlorine is often used to disinfect sewage treatment effluent, water supplies, wells, and swimming pools. Disposal Final placement or destruction of solid, liquid and hazardous wastes.
Methane is released naturally into the air from anaerobic environments such as marshes, swamps, and rice fields, and from symbiotic microbes in the guts of ruminant animals (such as cattle, sheep, and camels), and sewage sludge.
"Point" sources of chemicals include industrial discharges, waste incinerators, sewage treatment plants, and solid waste disposal sites.
Biological oxygen demand The rate at which oxygen disappears from a sample of water - a measure of deoxygenating ability commonly used as an index of the quality of sewage effluent.
Includes municipal waste or sewage. water purveyor An agency or person that supplies water. water supply system A facility designed for the distribution of potable water, typically including storage tanks and a network of pipes.
It can be used to manage utilities such as water and sewage mains, roads and power lines, or may help to clarify the relationship between different issues 'on the ground', e.g.

Combined Sewers: A sewer system that carries both sewage and storm-water runoff.
Septic system: Used to treat household sewage and wastewater by allowing the solids to decompose and settle in a tank, then letting the liquid be absorbed by the soil in a drainage field.

Bacteria, yeasts, simple fungi, algae, protozoans, and a number of other organisms that are microscopic in size. Most are beneficial but some produce disease. Others are involved in composting and sewage treatment.
It has set wastewater standards for businesses and boats, as well as water quality standards for any potential water contaminants, and funded the construction of sewage treatment plants to reuse wastewater.
