DRAFT 8 -17 -07 <br />As a final task, TKDA prepared a proposed capital improvement plan in the following <br />chapter. This plan leaves an option on storage size but does provide for a central storage <br />site and booster station site. It also shows the plant being built in 2017 and how it affects <br />the plan if delayed. <br />The plan as shown, has the booster station and Well No. 7 in the treatment plant building. <br />If the plant is delayed, the booster station and Well No. 7 should be built with the reservoir. <br />This would mean the treatment plant would be smaller and somewhat less expensive to <br />build at a later date. <br />All facilities on the list are needed as the City grows, except the plant is optional, based on <br />present regulations. The City's water demand is following the projection from the 2004 <br />water study prepared by TKDA. A slow down in development and conservation measures <br />may slow the growth pace. Therefore, timing may need to be adjusted based on actual <br />growth. <br />There was a question raised at the Council workshop about home water softeners and the <br />back wash water adding to the total water used in the City of Lino Lakes. In addition, there <br />was a follow -up question regarding the efficiency of home water softening versus softening <br />water at a City water treatment plant. <br />It is a part of a home water softener cycle to backwash the resin with salt water multiple <br />times per week which does use water and add to wastewater costs. It is also true that <br />there is an economy of scale for a City wide water softening plant. However, most cities <br />that start City wide water softening do so early before there are many thousands of houses <br />with home water softeners. As there are millions of dollars already invested in home <br />softeners, a City water softening plant was not considered. <br />Water Treatment Plant Study 25 13843.000 <br />
