City of Nashua, Public Works Division
Board of Public Works Meeting Date: June 16, 2022
Bryan Conant - Superintendent
Parks and Recreation Department
Central Irrigation Purchase.
To approve the purchase and installation of a central irrigation system from
Corbett Incorporated of Concord, MA for the sum of $85,850. Funding will be
through Department: 177 Park & Recreation; Fund: Capital; Activity; Central
Irrigation Project.
Quote and specifications from Corbett Incorporated.
The central irrigation project once completed will allow the departments
irrigation systems throughout the city to be managed through software that will be
web based. This will allow changes to be made to the systems through a PC,
phone, or tablet. The software will also provide notifications regarding and
problems that are occurring such as leaks. The software will also be able to
produce reports that will show how well the systems are preforming. This phase
of the project will include the software, and the installation of master valves,
clock modules and flow meters to the systems at Roby Park, Lyons Field, Shady
Lane, Charlotte Ave, Holman Stadium, Atherton Avenue, Artillery Lane, North
Common, and Murry Field. The software communication at Mine Falls, Lincoln
Park, Haines Park, and Ledge Park will be upgraded from 3G to 5G.
The system will save both employee hours and cut down on water usage the water
reduction is projected to be at least 25%. Central Irrigation, several vendors have
been contacted about installing new controllers, master valves and flow meters.
Given the fact that the locations of the controllers don’t have access to a Wi-Fi
fiber cable or internet router. A vendor that has its own server has to be used,
communication to the server will be done through a cellular communication
device also supplied by the vendor. The only vendors that are capable of
preforming this job scope are Corbett Incorporated and Winterberry Irrigation,
Which are the only two companies that bid on the work in 2018. Both Companies
where called by the superintendent in late March 2022 and both came to the city
to discuss the job scope and specifications. Corbett Incorporated has provided a
cost proposal to perform the job scope needed to complete the central irrigation,
while Winterberry still has not provided a cost proposal.
