Sewage is created by residences, institution, and commercial and industrial establishments. It can be treated close to where it is created (in septic tanks, biofilters or aerobic treatment systems), or collected and transported via a network of pipes and pump stations to a treatment plant. Sewage collection and treatment is typically subject to local and state regulation and standards.
