Connection to the existing 15" dia pipe in the alley is OK, however that is a very deep main and it's old concrete <br /> pipe (1917)—could be fragile, difficult and expensive. I suggest they use the existing side sewer pipe which is 6" <br /> dia PVC(2002)which is rather close to the proposed connection location anyway.Construction note hexagon#1 <br /> should be revised to inspect the existing 6" side sewer and its connection to the main—maybe some spot repair <br /> needed but would be easier and less expensive than building a new SS connection. <br /> 2. Sewer condition inspection was last done in 2002 and the condition was"POOR"for the main and manholes. <br /> Replacement or rehabilitation of this pipe is not currently planned, but work on regulator R4 at Chestnut is likely <br /> to happen before 2017. <br /> 3. The pipe shown as going diagonally to the NE from SSMH-D is going the wrong way—it diagonals to the NW and <br /> then North up the alley and is a 30" dia trunk. The 30" dia trunk continues going east from SSMH-D. At the NE <br /> cThe CB-A is shown connecting to an "SD" pipe which not correct—that is actually the 30"dia CS trunk. <br /> 4. Regarding the SD connection, kind of the same concerns as with the side sewer connection. There appear to be <br /> several existing connections to either the 15"or the 30"CS pipe and some are "standpipe"type. I suggest they <br /> find an existing"standpipe" connection that is relatively new and use that for the SD discharge. <br /> 5. There is high likelihood that a Stormwater separation project will happen to the north of this site and that the <br /> old 30"CS trunk would be re-purposed into a SD outfall going to SRO4. We would be able to divert the SD from <br /> this site into that outfall in the future. They should keep the SS and SD separated into the alley—the design <br /> shown is OK in that regard. <br /> That's about all I have time for right now. <br /> See you next week. <br /> Dave <br /> From: Dave Voigt <br /> Sent: Tuesday, July 15, 2014 4:30 PM <br /> To: Jane Zimmerman <br /> Cc: Gordon Witcher , / <br /> Subject: RE: Jacksons food store, Walnut & Everett ,' <br /> I will furnish you with some written comments before I leave. <br /> ia YC1 ( 1 <br /> From: Jane Zimmerman <br /> Sent: Tuesday, July 15, 2014 3:22 PM <br /> To: Dave Voigt <br /> Cc: Gordon Witcher <br /> Subject: RE: Jacksons food store, Walnut &Everett <br /> 1 <br />
