The deionized water system will be shutdown on Monday 12-12-11 beginning at 7:00 am and will be off for the remainder of the day. The shutdown is scheduled to facilitate the installation of new isolation valves within the piping system on the ground floor of the building. If deionized water is needed during this outage, it is available from the main supply tank in the mechanical room on the ground floor. Please contact either myself (9-8783) or Bob Montgomery (9-8783) to access the main supply tank.
