Rehabilitate Utilidors: HTHW Phase 2

Second phase of upgrading High Temp Hot Water system.

Project Update as of September 22, 2020

Phase 2 construction work is nearing completed.  Last summer’s work focused on repairs to the existing piping underneath the Central 4 and Central 5 parking lots, along the west side of J-Street, in the Heating Plant and Mechanical Services, as well as in sections of the tunnels, located underneath the Main Plaza.

This summer we are working on a broken section of piping under Lincoln Avenue that feeds the Commons apartment complex and upgrades to the heating system at the Physical Education building, including new boilers and getting things ready for an upcoming NYPA Co-Generation energy improvement project.

Project Overview

The High Temp Hot Water (HTHW) System at Purchase College is in poor condition in some locations and fair condition in other locations. Many components are original and have not been replaced or upgraded since originally installed. The college has been addressing ongoing leaks throughout the system and a number of previous emergency projects have revealed unreliable and potentially unsafe conditions in the system.

The system stretches from the Heating Plant located at the Facilities complex and stretches south, running parallel to Lincoln Avenue, until it reaches the Mechanical Services building, located beneath Student Services. From there it stretches out in both the north and south tunnels to supply the academic buildings.

Due to the size of this project, the project will be divided into two phases. The first phase addressed the most critical areas and was completed in the summer of 2015. This allows us to correct the portion of the system that is of greatest concern for safety and reliability.

Additional phases will address the remaining issues.
