Town of Waterville Valley 

Well Connection & Transmission Main Project

Waterville Valley, NH

Project Summary

The Town of Waterville Valley relied on three wells for its water supply. Several years ago, the Town had 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 involved constructing the WTP and piping a new well, #4, into it.

The second phase involved bringing the remaining two wells, #2 and #3, into the WTP. At that time, well #2 pumped directly into the water distribution system, while well #3 had been temporarily out of service to implement water quality protective measures around the well.

The project design included several components:
● A new connecting pipeline was installed from the well #3 pipeline to the WTP, which included a new pipeline crossing of the Mad River.
● The well #2 discharge pipe was disconnected from the distribution system and redirected into the WTP.
● Both well pumps (#2 and #3) were downsized from high- to low-head, requiring associated electrical, mechanical, and I&C changes.
● A new Mad River pipeline crossing was added for the distribution system pipeline to replace the existing crossing.
● A solar-powered control system was installed at well #3.
● Architectural improvements were made at the well #2 pump house.
● Security fencing was added at the WTP and well #2 pump house site.
