Melchert Block and Associates. Those plans have been reviewed and following are some <br /> remarks and concerns that we would like to share with you: <br /> . SHEET 2 <br /> . A wet tap valve should be used instead of a cut in the tee at the connection to the 12" <br /> I watermain at TH 96 and Hamline Avenue. Joint restraints should be provided through the <br /> casing. There is an inadequate distance between the forcemain and the watermain. There <br /> ClY'J. _(iJNG, should be a minimum of 10 feet of separation; in this case, there is only fi \ e feet. <br /> I E<!NfAL SHEET 3 <br /> IIJ,NNJNG <br /> I SOlID wASil In the note about connecting the 6" pipe to existing sanitary SKNIer manhole, mention should <br /> STlUC1\.!lA1 be made of a core drilling and using an S" boot. The meter socket should be located at the <br /> SUM'flNC control panel so Arden Hills will not have responsibility for unnecessary utilities. <br /> I 1WfIC <br /> TRANSPOIrATION QIIP,dinnco::- <br /> I ElfOllOol/MfCIW<<U.l __ 1. Are any manholes to TCAAP to be abandoned? <br /> !N(;lNf(iJNG, <br /> 1lVN; ...... 2.

A new invert <br /> will have to be constructed. <br /> SHEET 5 <br /> I <-- <br /> The section of forcemain that passes under the storm sewer should be insulated due to the <br /> I lack of ground cover. Show the change from PVC to DIP at the connection to the lift <br /> station. Move the lift station into the boulevard and out of Hamline Avenue. <br /> ~ES IN: <br /> I EAl'OUS <br /> ; PIllOltlAKE <br /> ST. PAUL <br /> I W!<SECA <br /> --- --- <br />
