The engineers did consider this alternative, but this has a number of major drawbacks, including:
- This would be considerably more expensive (and time-consuming) to build a completely new direct pipeline connection.
- Such a construction project would be much more disruptive to Southborough residents along the route of any new pipeline.
- Using the existing Southborough distribution system (with a few upgrades) provides a much more redundant supply path in the event of a pipeline break (versus a direct pipeline connection which offers a “single point of failure” to disable the entire connection).
As for a potential MWRA role in building a new pipeline for Hopkinton, the MWRA builds only its own infrastructure and not any local community infrastructure.
