The contractor inadvertently struck a force main with an excavator while trying to remove wet soil from their excavation. The creek that was affected was blocked to capture the release and return it to the system. The area adjacent to the release was abated and restored. The contractor replaced the damaged section of pipe and the Town's Engineering Department inspected the repairs. Please contact me if any additional information is required at this time. Thank you for the attention provided to our response.
