Lowell Wastewater Treatment Plant Faces Odor Complaints Amid Upgrades
Residents in Lowell are experiencing increasing odors from the wastewater treatment plant due to elevated temperatures and ongoing drought conditions. The Lowell Regional Wastewater Utility is implementing upgrades and odor control measures to address the issues impacting air quality in the community.

The Lowell Regional Wastewater Utility treats an average of 32 million gallons of wastewater daily, serving about 200,000 residents. Elevated temperatures and a Level 3 drought since June 1 have intensified odor emissions from the treatment process, prompting complaints from residents in various neighborhoods.
The facility, located on Duck Island, is the fifth-largest treatment plant in the Northeast and has been enhancing its odor control systems, including two chemical systems in operation continuously. Recent upgrades include the installation of new rubberized sludge garage doors to reduce odors, with full completion of tank improvements expected by January 2027. Ongoing evaluations are being conducted to further minimize odor impacts, with additional long-term strategies planned for implementation.
