Septic tank
A septic tank is an underground chamber made of concrete, fiberglass or plastic through which domestic wastewater (sewage) flows for basic treatment. Settling and anaerobic processes reduce solids and organics, but the treatment efficiency is only moderate (referred to as "primary treatment"). Septic tank systems are a type of simple onsite sewage facility (OSSF). They can be used in areas that are not connected to a sewerage system, such as rural areas. The treated liquid effluent is commonly disposed in a septic drain field which provides further treatment. However, groundwater pollution may occur and can be a problem.
Septic Tank (band)
Septic Tank are a British punk rock band formed out of Coventry doom metal band Cathedral. The band was originally formed in 1994, while the then-Cathedral were on tour, and later reformed in 2013 after Cathedral's breakup. Once the band reunited, producer and former member of the UK band Trouble, Jaime "Gomez" Arellano, replaced drummer Barry Stern, due to his death in 2005. The band have currently released one self-titled EP and one full length album, entitled "Rotting Civilisation".
