Upon application of the coating sysCem, the roof beams and seams <br /> will be caulked and the tank interior will be disinfected as per <br /> AWW�C652. <br /> • ll�y Interior: The dry interior is showing signs of minor <br /> � deterioration in several locations. <br /> � ���� The underside of the bowl and some areas within the access tube <br /> r..r <br /> _���` will require a spot abrasive blast clean to a SSPGSP6 `commercial <br /> �'�� ' blast' cleaning condirion.

Our comprehensive maintenance plans extend the period of time <br /> benveen major rehabilitations, allowing our clients to eliminate one or <br /> possibly nvo major tank rehabilitations over the typical i5-year useful <br /> life of a water tank, sa�ing hundreds of thousands of future tank <br /> maintenance dollars. <br /> Other Tank Improvements/Modi f►cations <br /> As identified in our inspection, there are several antennas located on <br /> the tank. These antemias, and the related equipment,will need to be <br /> removed prior to commencement of the rehabilitation activities. Any <br /> painting of antenna components not welded to the structure of the <br /> tank will be the responsibility of the telecom provider. The antennas <br /> can be reinstalled upon completion of the rehabilitation project. <br /> Based on the findings of our tank inspection, the existing manways, <br /> � hatches, and railings have been found to be satisfactory and compliant <br /> with current standards. <br /> A comprehensive listing of all proposed tank improvements and an <br /> implementation timeline is identified in the Scope of Services section <br /> of this proposal. <br /> Our proposed Scope of Services includes the follo���ing: <br /> • Tank rehabilitation <br /> • Safety improvements <br /> • Routine maintenance <br /> • Annual inspections <br /> • Periodic tank wash-outs and exterior power washing <br /> � recommended approach � page 8 <br />
