Feasibility Study <br />Water Treatment Plant <br />City of Lino Lakes, MN <br />WSB Project No. 015822-000 Page 21 <br />7. WATER TREATMENT PLANT SITE EVALUATION <br />7.1 Potential Sites and Land Acquisition <br />A potential site has been identified for the water treatment plant at the southwest intersection of <br />Birch Street and 12th Avenue South, as shown on Figure 3 and Figure 4 in Appendix A. The <br />site is located just east of Well No. 3 and is also within a mile of Well Nos. 1, 3. 5, and 6. <br />Therefore, raw watermain can be installed efficiently to treat these four wells at this central <br />location. A portion of the raw watermain is already in place from Well Nos. 1 and 6. The new raw <br />watermain that will be required for existing Well Nos. 1, 3, 5, and 6 and future Well Nos. 7 and 8, <br />if treated, is shown on Figure 5 in Appendix A. <br />The site is located within a 35-acre parcel that is currently privately owned. The City would need <br />to acquire 4 acres of land at a minimum for the construction of the water treatment plant. Vehicle <br />access to the site would be from 12th Avenue South, as shown in Figure 7 in Appendix A. The <br />chemical rooms would be located on the east side of the building with exterior doors for chemical <br />deliveries. <br />The site is located within the Rice Creek Watershed District. There are existing wetlands to the <br />west and south of the site. Surface water from the site drains west to the public ditch located <br />between the site and Well No. 3, which drains north to Wards Lake then west through the Rice <br />Creek Chain of Lakes. A stormwater retention pond and low maintenance landscaping should be <br />included in the site design to contain the additional stormwater produced from this site. <br />7.2 Water Treatment Plant Building <br />The proposed water treatment plant should include, at a minimum, the following features: <br />7.2.1 Architecture <br />The building architecture for the plant should include cost-effective sustainable design <br />features and provide an attractive appearance since the building will be highly visible to <br />the public. The water treatment processes within the building should be constructed of <br />cast-in-place concrete foundations and double wythe walls concrete block and brick <br />masonry or insulated load bearing precast concrete wall panels as shown below. The <br />roof structures should include precast concrete double ‘T’ roof beams to allow wider <br />spans without internal support columns. <br />WTP with Concrete Block and <br />Brick Masonry Walls <br />WTP with Precast Concrete <br />Wall Panels <br />The sustainable architectural features of the building should include natural daylighting <br />throughout, low maintenance materials, and building materials that meet or exceed the <br />current energy code.
