STANDISH, Maine — Construction is underway on a $12.8 million upgrade to the Sebago Lake Water Treatment Facility, which supplies drinking water to 15 percent of Maine’s population. A ground breaking ceremony will take place at 11 a.m. Tuesday, Oct. 2, at the facility, 2 White Rock Road.
The 17-month project will install a new ultraviolet light disinfection system and upgrade the 20-year-old ozone treatment process.
The Long Term Enhanced Surface Water Treatment Rule (LT2) requires surface water suppliers to enhance current systems to further treat for possible pathogens like cryptosporidium. Although the district has never
detected cryptosporidium in the water, there is a risk of contamination.
The project has been recognized by Efficiency Maine for its energy efficiency with a $300,000 grant.
