How will this development affect the Town’ water and sewer systems? Do we have enough capacity to support this development?

When the Town was developing the State Hospital Master Reuse Plan and drafting new zoning for the hospital area, the Town retained Pare Corporation to develop a conceptual water and sewer infrastructure plan and to estimate water and sewer demand for a proposal envisioned by the master plan. Pare Corporation’s report and materials are available on the Town website

After Pare Corporation completed their conceptual study, the Town’s consulting engineer Environmental Partners provided a peer review of the water and sewer infrastructure. Environmental Partners also analyzed the water and sewer usage information generated by Pare to determine whether the Town had sufficient capacity to absorb the potential new water and sewer demand. Environmental Partners’ report is available on the Town website

Environmental Partners’ findings were that:

  • MSH development’s estimated peak day water demands of 0.114 MGD could be accommodated under current authorized limits provided that the Town continues to be proactive with its water conservation programs.
  • MSH development’s daily sewer flow of 96,910 GPD could be accommodated by the existing 8‐inch PVC sewer system from Hospital Road to West Mill Street based on the assumptions stated in the report. 

Trinity Financial is not relying on these reports but rather commissioned its own studies as part of its due diligence.   These studies will be shared with the Town and peer-reviewed by independent consultants retained by the Town.   The findings will be discussed in meetings with the Board of Water and Sewerage that are open to the public.
