Rehabilitate Utilidors: HTHW Phase 2

Second phase of upgrading High Temp Hot Water system.

Project Overview

The High Temp Hot Water (HTHW) System at Purchase College was in poor condition in some locations and fair condition in other locations. Many components were original and have not been replaced or upgraded since originally installed in the 1970’s. The college had been addressing ongoing leaks throughout the system and a number of previous emergency projects had revealed unreliable and potentially unsafe conditions in the system.

The system stretches from the Heating Plant located at the Facilities complex and proceeds 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 heat during the winter months to the academic buildings.

Due to the size of this project, and that work could only be performed when the system was off (between April and October), the project was divided into multiple 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 addressed the remaining issues over the next several summers, including replacement of lines that ran under the Central 4 & 5 parking lots, across the Great Lawn down to the Physical Education building, and into the Mechanical Services building beneath Student Services.  Work also included upgrades in our Heating Plant and work in the Physical Education building as part of a joint project with the New York Power Authority (NYPA) on a co-generation upgrade.
