Madisonville residents may soon taste the benefits of a new city waste water treatment system. An ultraviolet disinfection system is one of the newest projects proposed for Madisonville’s upcoming budget. City officials say the bacteria levels in treated water have gone above state standards in the past. The Madisonville Messenger reports the existing waste water treatment plant was built in 1995. The city pays $90,000 a year for its upkeep. City officials have scheduled more hearings today on the issue.
