Our waste water goes into
the sewer lines leaving out homes. Industrial waste goes into drums that are
delivered to waste disposal sites.
In urban areas the sewer
lines connect and empty at our municipal waste water treatment plants in ponds
to allow solids to settle and oils to rise. These are separated
In rural areas our sewer
lines can connect to a Septic Tank that allows solids to sink to the bottom.
Water from the tank is piped to a sand and rock filtering system and cleaned
water flows out of pipes at the end of the filter system.
Sewage treatment is
the process of removing contaminants from municipal wastewater, containing mainly household sewage plus some industrial
wastewater. Physical,
chemical, and biological processes are used to remove contaminants and produce
treated wastewater (or treated effluent) that is safe enough for release into
the environment. Treated sewer water is released back to our rivers.
A by-product
of sewage treatment is a semi-solid waste or slurry, called sewage sludge. The sludge has to undergo
further treatment before being suitable for disposal
or application to land.
