4, <br />if <br />Page 2AUG M 19 mu <br />seven countyThe Prairie du Chlen aquifer supplies the 3,000 square miles, » <br />ground water pumped for public water suppl^T <br />7 ^nn gallons are pumped dally from this aquifer. That Is approximately <br />/,500 times more water than we are using. These figures clearly reveal the <br />magnitude of the Jordan aquifer and the gallons of water available. The U.S. <br />Geological Survey, titled: "Water Resources Investigations Report 83-4237", <br />talks of the hydraulic connection" of area surface lakes and th.s underground <br />water supply. This "hydraulic connection" completes a cycle of water being <br />extracted for public consumption and replenished by these surface lakes. The <br />pologlc cross-sectional .nap verifies the location of the Jordan aquifer and <br />Lake Mlnnetonl^ above, thereby allowing this hydraulic connection to occur. <br />The geothermal heating system now becomes an effective environmental heatinp <br />and cooling alternative by re-cyling water used. <br />4. Pump size — specs on pump: <br />Red Jacket brand, submersible pump. 10 horsepower. Three-phase power. <br />Pumping capacity of 150/gallons per minute. <br />5. Profile of discharge pipe statlon/elevations/percentage on grade: <br />lagoonfro® George Shoppe showing pipe going Into the <br />6. Temperature of discharge water - winter/summer: <br />Temperature of discharge during heating season: 39-40 degrees, U <br />Temperature of discharge during cooling season: 57-60 degrees. <br />This is explained In the information submitted by Terra-Therm, Inc. <br />Method of anchoring ends of discharge line: <br />Since the discharge pipe has been re-designed to go to the lagoon, <br />anchoring to lake does not apply, but a similar anchor and stand will be used <br />in the lagoon, drawing is included. <br />8. Depth and location of 100 feet discharge line - lake: <br />Does not apply after re-design of discharge pipe. <br />9. Submit list of hardships since applicant seeks a variance from the City: <br />SURFACE DISCHARGE <br />1. Natural drainage system of the Ulrich property and adjoining <br />properties would be over extended and undue erosion of <br />said properties could.occur. <br />2. Tax hydraulic capacity of the existing pond located on <br />southeast corner of Lot 1, 1595 Bohn's Point Road. <br />3. Contamination and degradated water quality by carrying <br />on shore nutrients Into the Lake. <br />4. Open water may occur causing dangerous liability situation. <br />7.
