Leominster, MA Water Quality Report
Where Your Drinking Water Comes From
The City of Leominster lies entirely within the Nashua River basin. It encompasses about 30 square miles of land. Much of the western half of the city includes state forest, watershed lands, and other protected open space. The City obtains its drinking water from the Distributing Reservoir system, including Haynes and Morse Reservoirs; the Fallbrook Reservoir at Wachusett Street; the Notown Reservoir system, including Goodfellow Pond and Simonds Reservoirs; and the Southeast Corner Well Fields off Jungle Road. Leominster also has an emergency connection to the Wachusett Reservoir.
Source Water Assessment and Protection
In 2004 the Massachusetts Department of Environmental Protection (MassDEP) completed a Source Water Assessment and Protection (SWAP) report for the sources serving this water system. MassDEP assigned an overall susceptibility ranking of high to Leominster’s water sources, based on the presence of at least one high threat land use within the water supply protection areas. The City of Leominster continues to actively promote source protection through aggressive land acquisition, installation of sanitary sewers, and continued public education efforts.
Water System Improvements
In 2015-16 the media was changed in all the water treatment plants’ filters and a new air scouring system was installed. In the last ten years Leominster Water Division has built a new plant at Distributing Reservoir, rebuilt and added pre – filter clarification at the Notown Plant, solved a seasonal raw water manganese problem at Fallbrook reservoir, built a new facility for chlorine injection and corrosion control at Southeast Wells and re-built the Pond Street Pump Station. The Morse Reservoir Dam was upgraded in 2019 and the reservoir is now back in use. Also, in 2019 a summer pilot study was initiated for an additional treatment system to reduce the amount of Total Organic Carbon in the raw water entering the Notown Water Treatment Plant, which will in turn reduce the amount of disinfection by products in the finish water, we will continue with a winter pilot study of this treatment system in 2020. We continue to inspect and improve our storage tanks, reservoir dams and intakes, and pump stations.
On the distribution system, a total of 6,755 linear feet of new water mains were added in 2019 on Lindell Avenue, Merriam Avenue, Devon Road, Buckingham Road, Dartmouth Street and Gibson Street. A semiannual water main flushing program has greatly reduced rusty water complaints. We are continuously upgrading our meter reading system. A total of 51 hydrants were repaired or replaced with new hydrants. This type of water system work will continue each year.
To help us provide the highest quality water available to our customers, the Water Division has an ongoing operator training program that encourages staff to achieve the highest qualifications in the field as possible. In addition, the reservoirs and wells are policed by a reservoir guard to prevent vandalism and potential contamination of drinking water. The Water Division has a cross connection control program to survey, inspect and test potential sources of cross connections in the commercial, industrial and residential buildings throughout the City of Leominster.
