It is never acceptable to dispose of any hazardous chemicals down the drain. Explosive chemicals such as gasoline pose a significant threat to sanitary sewers and should never be dumped down the drain. Explosive vapors can build up in sewers and create a hazardous condition, in addition, these vapors pose a threat to the technicians and contractors that maintain the system and could prove fatal in certain situations. The Town of Clifton Park conducts a Household Hazardous Waste Day annually where these items can be properly disposed of. The Town of Malta also participates in this program.
