ADOPTED THIS 2/ day of 1990. Z:Vr7r/d. MAYOR ATTEST: CITY CLERK Grout Resolution 8/16/90 cw MEMORANDUM August 17, 1990 TO: The Honorable Mayor & Members of the City Council FROM: Chris Waarvick, Wastewater Superintendent Bruce Bates, Assistant Wastewater Superintendent SUBJ: Purchase of Chemical Grout Products The Yakima Wastewater Facility has completed renovation of their grouter /packer vehicle which is now being utilized in the sealing of leaking sewer collection lines throughout the City. This program was presented in the most recent comprehensive sewer plan for collection system activities. It is estimated that the City could utilize ten tons of the necessary chemical grout per year for the sealing of leaking sewer lines. In addition to the chemical grout, we will utilize two types of catalysts which control the gel rate and consistency of the grouting product and a product for tree root control. A list is attached of the specific chemicals, usage rates, and prices to • explain the estimated costs per year of chemical grout. These figures appear significant, but are quite reasonable in comparison to costs associated with excavation and replacement of deeply buried sewer lines or the cost of outside contracted services for sewer line rehabilitation such as "insitu- form." The availability of a low toxicity grout to be used in our operation. The term "low toxicity grout" is used in the context of previous formulations which had a much higher concentration of acrylamide and made those formulations less desirable to work with from an employee safety standpoint. Research to date indicates only one chemical grout manufacturer which supplies the low toxicity grout and meets all other specifications related to our application. Therefore, we request that the City Council, based upon our investigation of this product, approve the sole source purchase of ten tons (more or less) of this product to be utilized yearly in the restoration and sealing of City sewer lines from Cue Incorporated, Rancho Cordova, California. Chemical grout products shall be purchased through a contract prepared by the Wastewater Division, Purchasing Division, and approved by the Legal Department. This quantity of grout and associated catalyst is estimated to cost approximately $43,000 per year. A 30 -day withdrawal clause could be stipulated in the contract to allow the City to withdraw from the contract in the event that additional sources of this low toxicity grout were located. cc: Bill Thompson HD -Daily BB4 COST ESTIMATE WORKSHEET FOR.
