Review Comments
July 21, 2004
General
1. Based on the A/E's certification in the Permit Application that all 15A NCAC 2H .0200
requirements regarding gravity sewers and force mains, and the Division of Water
Quality's Gravity Sewer Minimum Design Criteria adopted February 12, 1996 have been
met, a review of these items has not been performed. It shall be the permittee's
responsibility to ensure the plans and specifications meet the appropriate design criteria
and rules. Final approval of these documents will not imply approval of any variance
from these criteria unless specifically requested and granted. Failure to comply may
result in penalties in accordance with North Carolina General Statute 143-215.6A--143-
215.6C, construction of additional facilities, and/or referral of the N.C. Professional
Engineer to the licensing board.
2. Calculations
a. Provide a downstream sewer analysis for the gravity line below the pressure
system.
b. The schematic shown in the model does not show the street names. Indicate the
location of Arbor PI. with respect to the existing system.
c. Provide documentation to support the number of simultaneous pump operations.
Specifications
1. The grinder pump and wetwell specifications should be separate from the calculations.
Provide a copy of the pump curve for the calculations.
Low Pressure Sewer Customer Information
