7 Nearly 16,000 municipal Sewage collection and treatment systems in the US, serve over 75 percent of the population 1. The facilities have exceptional regulatory 2, environmental and safety requirements 3 with quality of life consequences for everyone. Sewage collection systems operate on gravity 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. Fuels and industrial solvents might also be in the collection system. All of these gases and vapors require monitoring to provide early warning of life threatening Station Wet Wells and screening exposes workers to sewer gas or floating flammables and these areas are Hazardous 4, Class I, Division 1, Group D. Placing electronic equipment in wet corrosive environments subject to flooding is not practical and seldom done anymore.
