Town of Mashpee Sewer Commission t 16 Great Neck Road North Mashpee, MA 02649 Chair Harris responded that the meetings are posted online and on the bulletin board inside Town Hall. Ms. Bigham questioned why bleach cannot go into the sewer system. Wastewater Superintendent Meader responded that it is a biological treatment process. Commissioner Lyons commented that bleach is one of the things that disrupts the sewer system. He explained that a few ounces of bleach used to clean the toilet are diluted when flushed with gallon of water but if one were to pour a whole gallon (or more) of bleach into the toilet, it would damage the sewer treatment process as it depends on bugs growing in the tanks to eat the solids and break things down. The bleach would kill the bugs. Chair Harris and Wastewater Superintendent Meader offered to speak with Ms. Bigham after the scheduled meeting to address her questions.
