AGENDA MEMORANDUM

Meeting Date:           May 9, 2011

From:                          Mike Thornton, Purchasing Manager

Subject:                      Purchase request 43571 to Siemens Industry Inc. for maintenance services of the Emergency Chlorine Scrubber System at the Turnpike Water Treatment Facility (WTF)

Staff Recommendation:

Staff recommends approval of purchase request 43571 to Siemens Industry Inc. for maintenance services of the Emergency Chlorine Scrubber System for the Environmental Services Department for a total amount of $27,983.00.

Analysis:

Emergency scrubber systems contain and neutralize chlorine vapors in response to a gas leak or catastrophic cylinder failure.  When a leak occurs, the pump and fan start automatically.  The fan provides sufficient vacuum to contain the chlorine gas and deliver it to the scrubber.  The pump circulates concentrated caustic solution over the scrubber packing to absorb the chlorine gas.

Chlorine scrubber system maintenance service is typically performed approximately every five years.  The Turnpike System was serviced, or washed eight years ago.  During a recent inspection by the manufacturer of the system, Siemens Industry, Inc., a build-up of crystals on the media and spray nozzles was found.  A complete acid wash service should be performed and 2,100 gallons of 20% Membrane/Rayon Grade Caustic is required to refill the unit.

The Emergency Chlorine Scrubber System used at the Turnpike WTF is proprietary to Siemens Industry Inc. and results in a sole source purchase from Siemens.  Both the price quotation and the sole source letter from the manufacturer have been attached for your review.

Options:

1.  Approve the purchase from Siemens Industry Inc.; or

2.  Such alternative action as the Commission may deem appropriate.

Fiscal Impact: 

Funding for the cost of this work, $27,983.00, is budgeted in the account listed and funded with available Renewal & Replacement funds.
