CITY OF ST. ANT11ONY REQUEST FOR- _CITY 'COUNC11, AC'T'ION • ----------------------------- ---------------------------------------------- Date Submitted Type of:�,Act:ion -Req.0°e.s-ted Agenda Ltem Number Resolution New .Business-] June 6 , 1984 ordinance Date Action Requested X Formal Action/Motion Title Water Report Other June 11 , 1984 ------------------------------------------------------------------------------- TO: Mayor and Councilmen FROM : Larry Hamer, Public Works Director ------------------------------------------------------------------------ SUMMARY DISCUSSION OF SUBJECT: Pumps #4 and #5 have recently been analyzed to determine their efficiency relative to meeting the City' s water needs . Data was taken from pumping records maintained for 1983• Well #4 is is first place in the running schedule, with a pumping capability of 1 ,656,000 gallons of water per day. Based on a 30 day operation , Well '4 can produce 49,680,000 gallons of water per month. Pumping Well #4 in first place gives the City only 65% efficiency. This is adequate for most of the year, with the exception of the summer months of June , July, and August . Wel1 15 produces 1 ,368,000 gallons of water per day and , again , based on 30 day operation , is capable of producing 41 ,040,000 gallons of water per month . Presently , the Clayton filling valve is .being readied for operation. When this is done, Well #5 will run in first place on the pumping schedule. 95 running efficiency will be attained with the change. We11 "5 will then pump the water directly to the customer and to the water tower , where after all is satisfied , it wi11 shut off. When the Clayton valve is in operation , excess water from the water tower wi11 flow into the reservoir. Well ,-!'4 would pump directly into the reservoir as usual . As a point of information , the peak' days for water usage in 1983 were July 13th at 2 ,252 , 100 gallons and August 19th at 1 ,964,400 gallons. This May , Well --4 was running 22. 2 hours a day to maintain the system. Note too, that the weekend of June 2-3, Well ='4 did not shut off and there was also a five foot deficit in the reservoir. SUMMARY To attain top efficiency from the City' s wells , we will change the operating system as outlined above, and we will be as prepared as possible to maintain the pumps. I Water demands began early this year and as you are aware, there has been construction delays wi..th the hookup to Rosevij le ' s water system. Although the City has never had i a sprinkling ban in the past , I -recommend we do so this summer. The ban could be in force according to odd/even calendar days. For your information , 1983 pumping data has been attached. Note: Well #5 is not filtered and- the line quality of the water must be closely monitored for Iron and Manganese during the next few months. y C(I�T MANAGER' S RF.VIE;I: COMMENTS
