Hartland Treatment Plant - Palmyra, Maine Wastewater Facility

Hartland Treatment Plant is a municipal wastewater facility located at 162 Pittsfield Avenue in Palmyra, Somerset County, Maine. It serves a small population of 1,092 residents, typical of rural communities in the region. The plant is part of the state's wastewater infrastructure managed under the US Clean Water Act. As a small-scale facility, Hartland Treatment Plant is expected to meet secondary treatment standards under the National Pollutant Discharge Elimination System (NPDES) permitting program. The US Environmental Protection Agency and Maine Department of Environmental Protection oversee compliance, ensuring that treated effluent meets water quality criteria for the receiving environment. The plant discharges into local waterways that drain into the Kennebec River watershed, ultimately reaching the Atlantic Ocean. Its operation helps protect downstream aquatic habitats and supports the ecological health of Maine's rivers and estuaries, which are vital for fisheries and recreation.

The plant's treated effluent enters small streams in the Kennebec River basin, which flows south to the Atlantic Ocean via Merrymeeting Bay. This watershed supports diverse aquatic life, including migratory fish species such as Atlantic salmon and alewife. The plant's discharge must meet state water quality standards to protect these ecosystems.
