Existing areas of concern include: Houle Circle (Node J-29), Grange View (Node J-32), Lamotte Drive (Node J-350), Clear Ridge (Node J-34), Lakeland Circle and Mount Court. These areas contain six inch water mains or are located on dead end streets, which causes existing fire flows to be just under the 1,000 gpm fire flow requirement. --., The new tower being 6.5 feet higher will help improve the Houle Circle, Grange View and Clear Ridge deficiencies. However, only increasing the existing main sizes or looping of the dead ends will make these areas surpass 1,000 gpm. " ! I The scheduled Peltier Lake Drive water main loop this year will increase the Lakeland Circle and Mound Court fire flows by over 400 gpm for a total over 1,400 gpm. Completing the Peltier Lake Drive wa~er main loop all the way to node J-385 on CSAH 14 will increase the flow over 600 gpm and put the fire flow around 1,675 gpm. Both of these increases are without the new tower. Completing an 8" water main loop to the MCES lift station via Lamotte Drive and Heritage Street, will increase the MCES area in the ultimate system by 1,800 gpm for a total available fire flow over 2,500 gpm. The new tower and mains to the east side Commercia1lIndustrial areas will provide fire flows just over 3,500 gpm when entirely interconnected with the IDtimate System. The available fire flow for the dead end 8" main to node J-28 on 21st Avenue is only 1,422 gpm. Looping that system to node J-I04 on 20th Avenue will increase the fire flow to above 2,500 gpm. "'-, Refer to Table No. 3 below for a model comparison of the existing sytem fire flows to the ultimate system fire flows. Refer to Figure No.2 and Figure No.3 for the existing and ultimate modeling node locations. 19 Water Tower Feasibility Report
