McIntyre Library Construction Update

As early as today, workers will begin the "clean and treat" process of the pipe on the Lower Level and in the Penthouse (above Fifth Floor). The process will involve using a compressor to pipe an acidic foam into the pipes, which will then be flushed outside into tanks. Workers will then flood the pipes with water with a bacterial treatment additive in it. That will then be flushed. The process should not be very disruptive. You can expect some compressor noise and there may be some odor from the process on the Lower Level or on the Fifth Floor, but the chemicals they are using are natural and safe.
