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 con1lic;t with the plans on this <br /> I 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 intluent COMection goes. This sh>Juld be clearly <br /> (. identified. <br /> .. SHEET 11 <br /> Use restrained joints (St. Paul WafJ:t Utility Standard) instead of thrust blocks. For the <br /> 1 <br /> outside drop, use integI3l bottom and base with precast S. M190 degree base bend. Use <br /> sand instead of concrete for b~t"lriill around outside drops. TIe rods are less desirable than <br /> I Megalugs. The 30 minute test period docs not comply with A WW A; it should be at least <br /> two hours in duration. There should also be a tr.K:er wire for the forcemain. <br /> I We have forwarded our Il:COl!tm,.,,"~tiQns to the Nalional 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 /> I Sincerely, <br /> I ~CQNSULTING ENGINEERS <br /> 'Uxl~~ <br /> . <br /> I '. <br /> .
