What is it?

The project is to provide a new source of water supply for the Bethel Public Utilities Commission (PUC) to serve our customers. 

What does it include?

The project includes a high yield well at 1.15 million gallons per day and new water treatment building.   Water treatment system includes filtration for iron and manganese removal, backwash and recycle backwash systems, chemical treatment including disinfection and corrosion control, electrical and instrumentation components, operator control room and emergency power generation.

Why being proposed?

  • Provide additional supply to maintain a Connecticut Department of Public Health required Margin of Safety for the 50 year planning period
  • Allow the aging reservoirs to be retired.These sources have low yield, water quality issues and are not cost effective to upgrade
  • Extend the life of the Maple Avenue Wells by alternating the use of each of the wells

Why now?

This source has been investigated as a potential water supply for over 20 years.  The poor water quality of Chestnut Ridge Reservoir (excessive trihalomethanes) and Eureka Reservoir (taste & odor) necessitates their upgrade or replacement.  Based on engineering reports, the two reservoirs’ upgrades would be costly and produce a low yield of water and another source of water supply would still be required in the future. 


The project has been identified and included in the Bethel PUC Capital Improvement Plan and the CTDPH required Water Supply Plan.


The Bergstrom Well WTP has been approved by the state regulatory agencies.


How is it being paid for?

The project will be paid for through a low interest loan at 2% over 20 years, reduced by all available grants.  The project is eligible for a total of $3.1M in grants.  Payment for the appropriated sums shall be paid by the water account users of the Bethel PUC.


If approved, what is the Construction Schedule?

Construction would be expected to start this spring (2023) and it is anticipated to be complete in 2 years (2025).
