SECTION 3 — EVALUATION OF EXISTING FACILITIES <br />A. GENERAL <br />This Section provides a summary of existing water supply, treatment, storage and <br />distribution facilities for the City of Ramsey. In addition, infrastructure needs will be <br />assessed for each of the facilities. <br />B. WATER SUPPLY AND WELLHEAD PROTECTION <br />1. Existing Water Supply Facilities <br />The City of Ramsey is underlain by two aquifers, the Ironton -Galesville and the Mount <br />Simon -Hinckley formations. The City's wells are currently located in the Ironton - <br />Galesville formation, which is located above the Mount Simon -Hinckley formation. <br />Wells in the Ironton -Galesville formation are currently producing between 210 and 1450 <br />gpm. <br />The City has an established Wellhead Protection Plan to help protect the wellhead <br />protection areas from contamination from the land surface. Estimated costs for <br />maintaining the City's wellhead protection program are reflected in the proposed water <br />rates discussed in Section 6. Grant money is also available from the State of Minnesota. <br />A summary of the specific well construction is presented in Table 3.1 <br />City Well No. <br />Unique Well No. <br />Year Installed <br />Capacity (gpm) <br />Casing (in.)/ <br />Depth(ft.) <br />Total Depth <br />1 2 <br />161441 416183 <br />1984 1987 <br />700 220 <br />14 in/ 14 in/ <br />243 ft 240 ft <br />448 ft 320 ft <br />Table 3.1 <br />Well Construction Summary <br />City of Ramsey, Minnesota <br />3 4 5 6 7 8 <br />580303 580313 593672 706840 743832 743833 <br />1997 1998 2000 2004 2006 2006 <br />1450 850 850 900 850 1400 <br />24 in/ 24 in/ 24 in/ 30 in/24 in 30 in/ 24 in 30 in/24 in <br />222 ft 191 ft 210 ft 180 ft 230 ft 120 ft <br />345 ft 321 ft 316 ft 370 ft 320 ft 310 ft <br />2. Water Supply Capacity <br />The Recommended Standards for Water Works (Ten States Standards) <br />recommends that the average day demand be met by the firm well pumping <br />capacity. In addition, the daily well output is calculated based on operating for 20 <br />hours per day to allow 4 hours per day for aquifer recharges.
