Town of Waterville Valley 

Well Connection & Transmission Main Project

Waterville Valley, NH

Project Summary

The Town of Waterville Valley relies on three wells for its water supply. Several years ago, the Town initiated a project to pipe the wells into a central treatment facility (WTP) to consolidate chemical treatment and meet a C-T disinfection requirement. The first phase was to construct the WTP and pipe a new well, #4, into it. 

The second phase is currently ongoing. This will bring the remaining two wells, #2 and #3, into the WTP. Currently, Well #2 pumps directly into the water distribution system and Well #3 has been out of service to improve water quality protective measures around the well. 

The project is expected to be completed by late 2022. Included in the design are: 

  •    A new connecting pipeline from the Well #3 pipeline to the WTP including a new pipeline crossing of the Mad River
  •    Disconnecting the Well #2 discharge pipe from the distribution system and redirecting it into the WTP
  •    Downsizing the well pumps for both wells from high- to low-head with associated electrical, mechanical, and I&C changes
  •    Adding a new Mad River pipeline crossing for the distribution system pipeline to replace the current crossing
  •    Adding a solar-powered control system at Well #3
  •    Architectural improvements at the Well #2 pump house
  •    Adding security fencing at the WTP and Well #2 pump house site
