PRorEtr UNDERGROUND WATER <br /> 9 April 1999 <br /> Mr. Ray Borges <br /> San Joaquin County <br /> Public Health Services <br /> Environmental Health Division <br /> 304 E. Weber ST., Third Floor <br /> Stockton, CA. 95202 <br /> Re: Water Well &Pump at Sutter Home Winery <br /> Dear Mr. Borges, <br /> I am submitting for your consideration and approval the design of the water well&pump at the <br /> Sutter home Winery. <br /> As your are aware we drilled two tests wells and extracted samples. Mr. Bill Holden of <br /> Facility Construction Management has informed me that they plan on treating the water <br /> and want the capability of pumping 1000 gallons per minute at some time in the future. <br /> However they will not be needing that flow as of the present and under the current <br /> demand the winery will require 150 gpm at 100 psi. Their plan is to run it through <br /> treatment then store it in large fresh water storage tank. I have communicated to him that <br /> you will be needing the design proposal before you approve our permit. <br /> We plan to install the following; <br /> Gravel Pack Reverse Circulation Water Well <br /> 225 ft 26"Borehole with 195 ft 16" .250 steel Pipe and 30 ft of 16" Stainless Steel Well <br /> Screen including 100 ft Sanitary Grout Seal, Gravel-Packing, Test Pumping, and Pad <br /> The screens will be set from 225 to 195 ft according to the a-log. You will note that from <br /> 80 feet there is basically clay until 200 ft. Thus the 100 ft grout seal should prove <br /> acceptable. <br /> Pump and Tank <br /> 15 HP Grundfos Stainless Steel Submersible pump installed With 1500 gallon galvanized <br /> tank designed to ASME Code with a working rate of 125 psi. Proposed pumping fate 150 <br /> gpm @ 100 psi. I will be submitting final curve sheets after well is drilled and tested to <br /> match the pumping rate. <br /> 2024 EAST CHARTER WAY, STOCKTON, CALIFORNIA 95205-7016, TEL: 209/462-7676, FAX: 209/462-5597 <br /> GEN ERAt ENGINEERING CONTRACTORS, L Icense No .
