Town of Lincoln 

Fire Flow Assessment & Capital Improvement Plan

Lincoln, NH

Project Summary

The Town of Lincoln’s water distribution system is hydraulically complex with six pressure zones, three water storage tanks, a water treatment plant, a well and five distribution booster pumping stations. Over the years, Hoyle Tanner has updated the Town’s water distribution hydraulic model using it to perform several impact analyses and recommendations for distribution improvements. 

Hoyle Tanner also developed the water asset management program for the Town. Working closely with town fire and public works staff, we performed an assessment of the system’s fire flow level of service, identifying areas of inadequate fire flow rate and duration.  Included was performance of hydrant flow tests throughout the town, as well as elevation checking for updating the model calibration. We followed the assessment with developing a Capital Improvement Plan (CIP) designed to improve both fire flow rate and duration. The CIP included two new water storage tanks, two new pumping facilities, the addition of a pressure reducing valve and pipeline modifications and improvements – all prioritized in terms of cost and effectiveness.

The CIP serves as a blueprint for long-term sustainability of the water distribution infrastructure to meet current and future needs.
