<br /> <br />Note: <br />a. Neutralization chemistry for post-cleaning backwash water is provided by <br />Hawkins in the form of 140 gallons of Sodium Hydroxide 30% solution. <br />b. Defoamer may be needed and will be provided by Hawkins. <br />c. Installation labor is not included and shall be by others. <br />d. Product will ship in 40 each of 50 lb bags. <br />e. Each filter will be dosed with ten (10) 50 lb bags. <br /> <br />The cleaning of the filter media is not the 2016 Adopted Budget. Staff has reviewed the <br />water department budget and in fund 700-4823-5150, Repairs Utilities, there is a <br />budgeted $17,500.00. (This is for any repairs needed to the water system such as water <br />main breaks, repairs of fire hydrants and repairs or replacement of water main gate <br />valves.) <br /> <br />Recommendation: <br />Staff recommends the City Council approve the quote from Hawkins Water Treatment <br />Group of St. Paul, MN, to provide the chemical needed to clean the filter media as well <br />as the supervision in applying the chemical at Water Treatment Plant #2, in the amount <br />of $7,140.00. Staff also recommends the Council approve a contingency fee of 10%, <br />($714.00) to cover any unforeseen expenses for cleaning the filter media. The monies <br />to cover this process will be taken from account 700-4823-5150, Water Infrastructure <br />and Equipment Maintenance budget. <br /> <br />Respectfully submitted, <br /> <br /> <br />Don Peterson <br />Public Works Supervisor <br />
