A hydrant should be placed near the wet tap valve to allow air to vent. <br /> SHEET 8 <br /> I A hydrant should be placed near station 10+00 on Ham1ine Avenue, and station 15+00 <br /> for flushing. <br /> . SHEET 9 <br /> I A remote panel makes removal of pumps, and especially a level transducer very difficult. <br /> As a note of caution, understand that the cast iron hatch will be extremely heavy. A water <br /> trap should be provided in the drain line as a check valve is ineffectual for this purpose. <br /> . Use a stainless steel lifting chain. (The specifications conflict with the plans on this <br /> matter.) The inclusion of a stilling well is unusual in a lift station of this size. We were <br /> unable to tell where the second booted influent coMection goes. This sh'Juld be clearly <br /> .- identified. <br /> SHEET 11 <br /> I Use restrained joints (SI. Paul Water Utility Standard) instead of thrust blocks. For the <br /> outside drop, use integral bottom and base with precast 8" M1 90 degree base bend. Use <br /> . sand inste3d of concrete for backfill around outside drops. Tie rods are less desirable than <br /> Megalugs. The 30 minute test period does not comply with A WW Ai it should be at least <br /> two hours in duration. There should also be a tracer wire for the forcemain. <br /> I We have forwarded our recommendations to the National Guard's engineers for correction. <br /> If you should have any questions or concerns regarding the National. Guard Utility <br /> . Extension project, please contact Greg Stonehouse at 644-4389. <br /> Sincerely, <br /> I ~.
