MEMO To: CLERK -ADMINISTRATOR AND CITY COUNCIL <br />FROM. DIRECTOR OF pUBL1C WORKS/COMMUNITY UE'VF;LOPMF.'N'I' <br />DATE; JUNE 20, 1985 <br />SUBJECT: WATER PILOT PLANT STUDY POk WELL NO. 3, <br />PHASE I1[ <br />As you may recall, the City has conducted two pilot studies <br />on well number 3 water. The City is attempting to solve the <br />problem of high iron content and high manganese content in <br />weLL number 3 drinking water. The first two pilot studies <br />Or treatment processes were not as successful as we would <br />like. Theretore, Toltz, King, Duvall and Anderson (TKDA) <br />and I recommend conducting pilot plant studies for treating <br />well number 3 water with ozone. A copy of TKDA's letter is <br />attached for your review. <br />Mr. Tom Kirk of TKDA has indicated to me that the larger <br />ozone equipment supplying companies charge approximately <br />$30U-$400 per day just to rent their equipment. Therefore, <br />a thirty -day pilot study would cost approximately $12,000. <br />Therefore, I have located a supplier of ozone equipment who <br />will conduct the pilot study for a more reasonable cost. <br />Tile company is Waterco, Inc., 251 - 5th Street NW, New <br />Brighton, Minnesota 55112 (636-3067). Attached please <br />find a copy of his quotation and exhibits. The cost of the <br />pilot study is as follows: <br />Waterco, Inc. $4,825.00 <br />Serco Labs (Manganese Tests) $ 500.00 <br />Contingency $ 475.O0 <br />Report (By City Staff) $ - 0 = <br />TOTAL ESTIMATED COST $5,800.00 <br />This work is scheduled under the long term maintenance <br />and repair. program. The money for this pilot study is in <br />the 1985 budget under line item 700-122-4123. <br />RECOMMENDATION: I recommend awarding the pilot study for <br />well number 3j Phase III to Waterco, Inc, for a not to <br />exceed price of $5,800.00. <br />SWT/mjs <br />Attachments: <br />
