Reservoir aqueduct will be open for walking.
CLINTON - The old Wachusett Reservoir aqueduct, which was once used to bring water to Boston, will be in use again - this time as a walking trail.
The state environmental affairs office and the Massachusetts Water Resources Authority announced they will allow public access along the grassy tops of the historic Wachusett, Sudbury, Cochituate and Weston aqueducts.
They would form a trail network through Berlin, Boston, Clinton, Framingham, Marlboro, Natick, Needham, Newton, Northboro, Sherborn, Southboro, Wayland, Wellesley and Weston.
The aqueducts, which currently serve as emergency back-up water supplies, have the potential to create 40 miles of trails if the MWRA and communities work together. Not all trails would be connected.
As the water system was modernized, the old aqueducts were replaced with a deep rock aqueduct and covered storage tanks.
