Proposed Water Tank Replacement Project

 water storage tanks

Water Storage Tank Facts:

Under existing conditions, Weston’s water system has no active storage; this storage deficit will worsen over time if not addressed. To consistently and effectively meet the Town’s needs for residential use, firefighting, and emergency situations, a water system must have sufficient tank space at the right elevation to hold water for active storage. Active storage in a water system meets the fluctuating demands for everyday water use and includes sufficient volume for firefighting needs.

Water Storage Tank FAQs

  • What is active storage?

            No mechanical equipment is needed, gravity makes water flow out of the tanks to serve the Town 

  • Why do tanks need to be increased in height?

            Height equals pressure. The current elevation is too low to serve the community.

  • Why not purchase more MWRA water?

             Weston has adequate supply, but insufficient storage capacity for the water it receives. Enough water is coming into the system; we simply have no way to effectively use the water the Town receives.

  • Can we use pumps instead of increasing storage volume?

    Not without significant cost and the possibility of service disruption due to the need to service or repair a pump station. We would need more pumps, and they would need to be larger. Pump maintenance would be a significant expense. Existing distribution piping wouldn’t support high flow demands or the higher pressures needed to overcome friction in the pipes. Relying on mechanical pumps for service is risky, and pumps may not be able to keep up with high demand situations such as an active fire or high usage during the summer when water usage increases.

  • Can booster pumps be provided to affected areas?

             Tanks with sufficient capacity positioned at the correct elevation are the most cost effective and reliable way to ensure flow of water throughout the community in all types of situations. Trying to resolve the problem with booster pumps will require numerous pump stations, and significant reconfiguration and replacement of water mains throughout the Town’s system.

  • Can conservation efforts eliminate the need for new Tanks?

            Weston has been promoting conservation for years through various methods, including tiered water rates, requirement for low flow plumbing fixtures, and even/odd watering days in the summer.  Any reductions in water usage from conservation measures have likely already been realized.  Conservation cannot make up for our storage deficit. The storage deficit can only be solved by tanks that are properly sized at the correct elevation.

Additional Documents and Links:

Water storage is an essential component of a municipal water system.  Water storage stabilizes pressure fluctuations, provides a cushion to the system during peak demand periods and meets firefighting and emergency needs. Although Weston has three storage tanks, there is a serious storage deficit in the system that requires immediate attention.

  • The Paines Hill, Cat Rock and Doublet Hill Water Storage Tanks are nearing the end of their useful life.
  • Both the Doublet Hill and Cat Rock tanks will require recoating within 10-15 years if they are not replaced.
  • The Paines Hill tank is structurally and aesthetically in poor condition and requires significant interior and exterior rehabilitation.
