The facilities have exceptional regulatory2 , environmental and safety requirements 3 with quality of life 3 consequences for everyone. 2 Sewage collection systems operate on gravity 4 flow to central lift or pumping stations which deliver the raw sewage to a treatment plant. Sewage decomposition produces Sewer Gas (Carbon Dioxide, Methane, Hydrogen Sulfide, et al) which presents Oxygen deficiency, toxic gas and the risk of fire or explosion hazards. Remote Calibration Fixture Fuels and industrial solvents might also be in 821-0218-01 the collection system.
