SECTION D: CONDITIONS OF CERTIFICATION
1. It is the responsibility of the owner/developer to verify, by an engineering study, whether it is possible
to connect by gravity line to the existing City sewer system (a private lift station may be installed but is
not desirable). The City may require, at its option, the verification to be in the form of a letter signed by a
professional civil engineer.
2. The City does not guarantee that a stub exists for all properties, nor does it guarantee the condition or
location of the stub.
It is the responsibility of the owner/contractor to have an approved connection from the building sewer
to the City's sewer main. If there is a PVC stub, it is in good condition, and the owner/contractor can
locate it, then it is available for use. If the existing stub is concrete or clay, the stub shall be lined or
replaced with PVC. A Closed-Circuit Television (CCTV) inspection shall be performed on the existing
stub to determine if it can be lined. The determination of the condition of the existing sanitary sewer
stubs shall be the sole responsibility of the City and the City's decision shall be final.
If the stub is broken or the City determines that the stub's condition is not acceptable, it shall be the
owner/ contractor's responsibility to repair the stub, replace the stub at the existing tee, or to install a
new stub and tee directly into the main. The method of repair/replacement to be determined by the city.
NOTES:
I hereby certify that the above sanitary sewer information is true. This certification shall be valid for the
calendar-year that it was created.
