The City of Yakima (City) Water Treatment Plant uses an onsite sodium hypochlorite generator to produce chlorine for drinking water disinfection as required by state and federal regulations for water quality. The generator utilizes an electrode assembly cell and electricity to produce sodium hypochlorite from a brine solution. This electrode assembly is encased in an acrylic casing.
The acrylic casing developed cracks and has been recently replaced. Cost of the electrode with tube assembly and the recently purchased acrylic casing is over the $50,000 threshold which requires Council approval. The electrode with tube assembly is reaching the end of its useful life. It is therefore prudent to replace that assembly before it fails.
As described in the attached Sole Source Justification form, De Nora Water Tech LLC is the sole manufacture of the assembly for the Clortec generator used by the City. The City followed the requirements of RCW 39.04.280, City Charter and Municipal Code for sole source purchases over $50,000, as De Nora, the manufacturer, sells directly there are no other vendors. The sole source purchase, including a 2-year warranty, of just the electrode with tube assembly is in an amount not to exceed $42,225 (see attached Sole Source Justification and Quote).
The electrode assemble with tube assembly purchase is funded through Water Capital Fund 477. As was the previous purchase of the acrylic casing. |
