Thanks Jason, we will add that note to the plans. The manhole location is pretty set as we are placing it between the
existing water line and proposed duct banks. The Contractor will have to make adjustments to the pipe segments
accordingly.
Thanks,

Thanks Jonathan,
Yes, please add the note to the drawing that a full length of ductile iron sewer pipe be centered over the existing water
main so that the sewer pipe joints are as far from the water line as possible. From the drawing, it appears that this may
require the reconfiguration of manholes. Will that be the case?
Thanks,

Hey Jason,
Sheet C-201 is attached for your reference. We are meeting the requirements of 15A NCAC 18C .0906c, in that we will
have 18 inches of separation from the outside of the water main and the outside of the sewer. This stipulation allows
for the water to be below the sewer. We can add a note to our drawing that requires a full length of ductile iron sewer
pipe be centered over the existing water main so that the sewer pipe joints are as far from the water line as
possible. Please let me know if you have any further questions or need any additional information.
Thanks,
Jonathan

Hi Jonathan,
You're correct in that a sewer over a watermain does not meet the separation requirements of 15A NCAC 02T
(f). Therefore, 15A NCAC 02T (g)(3) must be met (see below). I don't think we have a copy of the plans (Sheet C-
201). Does the sewer crossing over the waterline meet watermain standards (18C .0906)?

for public water main horizontal or vertical separations, alternatives as described in 1 SA NCAC
18C .0906;

Hey Jason,
Sorry for not providing any clarification with that 'no' response. It does not comply with the chart shown in IX.1 where it
states that water over sewer is preferred. As shown on Sheet C-201, we have a proposed sewer main crossing over
existing water mains; however, we are still meeting the 18" separation.
Please let me know if you have any further questions.
Thanks,
Jonathan

Subject: QUESTION: WQ0043938 - UNC McColl Building Addition and Renovation (MBAR) sewer application
Jonathan & Nick,
We're reviewing the referenced application and have the following question:
Item IX.2 is checked "no" for meeting water main separation requirements. This doesn't appear to be explained in the
narrative. Please explain.
Thanks,
Jason
