2. The work will require NTMWD to remove one or more pipes, and possibly pumps or other equipment, from normal operating service. The allowable time that the infrastructure can remain out of service, referred to as the shutdown tolerance, will be finite, will vary from pipe to pipe, and will vary based on the time of year according to seasonal demands in the NTMWD system.
