Re: 15" Sanitary Sewer Line - Riverchase
Dear Steve:
We have reviewed the above subject plans for your concern
regarding the backing up of sewage in the subject sewer line.
Our review took into consideration your statement that the sewage
is backed up approximately 320' from the point of entry to the
TRA interceptor. After review of the as-built plans showing the
angle of entry where the 15" SS ties into the TRA system, we
recommend that further engineering be pursued to improve this
present condition prior to final acceptance of the facility.
It would be appropriate in this situation to have Terra and their
consulting engineers re-evaluate the situation and propose an
acceptable solution to you that will alleviate this present
backing up situation. On a gravity sewer line, the City should
look for a design that allows for the discharge of sewage to not
be restricted by any opposing velocity head.
We hope this accommodates your concerns.
Sincerely,
Kevin Peif'fe~
