Discussion and possible action on any and all matters regarding the approval of Layne Christensen Company proposal for replacements of manganese water treatment pressure vessels and treatment media at three (3) well sites. (Manuel Rojas, Assistant Director of Public Works)

Over the past few years, staff has been working on repairs on the Layne Christensen Company, Manganese Treatment Unit pressure vessels on all the Well Sites.  Through the years, pinholes have developed on the pressure vessels.  In this Fiscal Year 2017-2018, staff budgeted to make the repairs of the pressure vessels and treatment media.  Reviewing possible repair options, staff received some quotes on vessel repairs as well as for new media.  From the cost proposals received, the budgeted allocation for the repairs on Well Site #4 and Well Site #6 for Fiscal Year 2017-2018 is sufficient to cover the repairs and media for pressure vessels at Well Site #3.  After review, and due to proprietary design, it would be more economical for the City to contract Layne Christensen Company on the repairs and media replacement.  Otherwise, any other company would have to re-create the design at extra cost.  Staff reviewed the new pressure vessel specifications, visited Maywood Mutual Water Company, approved the new specifications with a 2-year warranty and we are confident the new pressure vessels will perform.  Staff recommends the purchase in an amount not to exceed $292,481.36 and to waive formal purchasing procedures under these circumstances which are allowed under San Luis City Code-Purchasing Section 36.01(H). 
 

I MOVE TO WAIVE FORMAL PURCHASING PROCEDURES UNDER CITY CODE 36.01(H) FOR THE REASONS PRESENTED AND I MOVE TO APPROVE THE REPLACEMENTS NEEDED FOR THE MANGANESE TREATMENT SYSTEMS AT WELL SITES #3, #4, AND #6 AS PRESENTED.
