~ In discussion, it was noted that the cost of the. 6" line is estimated @ $130,200 and the combination 12" and 8" line @ $170,500 (difference of $40,300). It was queried whether the Improvement will provide any service to the mobile home park. Lee and Christoffersen explained that Arden Manor's new wel I is in the Hinckley formation which Is very high In Iron content, but good potable water. It usually needs treatment to remove the iron. Christoffersen said the City anticipated that Arden Manor would probably connect to CIty system at some time; it Is debatable whether the Arden Manor system can withstand the pressure of the City ~Y~1em; Arden Manor has very low pressure at the present time. It was noted that th~^~re hydrants (existing and proposed) can be used for emergency fire protection at Arden Manor. Christoffersen was asked If an 8" I ine would. be sufficient for fire protection. Christoffersen said, if the system could be looped, an 8" main would probably be sufficient; feels the 12" main Is needed to properly serve the lumber yard, which has . been one of the po I nts of concern; noted that 6" or8" ma i ns are usua II y adequate to serve residential. Christoffersen said he'd have to check figures again to determine the adequacy of an 8" system. MeAl lister asked Christoffersen to explain who paid for the main south of, and along the west and north of Round Lake. Christoffersen said it was partly assessed to abutting property owners on front foot and areas basis and partly paid by the City. McAllister asked why City did not run water to this area at that tlme1 Christ- offersen said he believes It was because the residents objected, and It was deleted from the project; recalls the assessment at that time was about $13/front foot, plus acreage assessment for large parcels. Lee was asked what the chances are for future contamination of the Arden Manor wells. Lee said the Oepartment of Health feels they have good protection from con- tamination in the Hinckley formation for many years; of course, there is no guarantee. Hicks asked why Arden Manor did not connect to the City system Instead of putting in the new we II. I twas exp I a i ned that a reduct i on va I ve was proposed to be 1 nsta II ed to reduce the pressure through the Arden Manor lines; cost of water @ 87~/M gal. (an on going cost) and the sewer rate, which is tied to the water usage are probably the reasons. Hicks asked the residents if EPA pays the total cost, would they go for the 12" main. Werllen said yes, but feels City can get by with an 8" main; would want the 12" if EPA pays entire cost; 12" would be better, but feels 8" is o.k. Geske was asked how his hookup charge to Arden Manor system compares to the proposed $15.75/foot charge1 Geske said his hookup cost was less. Woodburn noted that about 20 years ago there was a calculation on the effect of City water on fire insurance. McNlesh reported that a substantial reduction 1n fire insurance rates resulted in areas of the City with municipal water. De Witt noted that Arden Manor can charge anything they want to for use of their water; can even stop service if they desire. . -4-
