Project Updates
Massachusetts Water Resources Authority


MWRA’s Capital Improvement Program consists of projects to modernize and improve the wastewater and waterworks systems serving 61 member communities in eastern and central Massachusetts. Projects range from upgrading treatment facilities to construction of new storage facilities to replacement of 100-year old pipelines.

Some of these projects take place within city streets and can have impacts on neighborhoods. MWRA’s Community Relations department works with municipal staff and residents to ensure good communications during these projects.

Regular updates on on-going projects can be found here:
