Project Experience
Fee Fee Creek Sanitary Relief
Owner: MSD
Commencement: Jan 2004
Construction Value: $3,200,000
The objective of this
project is to provide a design for a sanitary trunk sewer replacement in
the Fee Fee Creek watershed. The new trunk sewer will eliminate
surcharging and associated backups and enable the removal of the
sanitary sewer overflow (SSO) bypass. The project reach of trunk sewer
is approximately 7,800 feet long and serves commercial and residential
properties. The design considers the staging of the pipe installation
to facilitate continued use of the system during the construction
phase. ABNA will also provide the boundary survey and strip map,
topographic survey and all easement and working room plats.
North Price to Pernell Sanitary Relief
Owner: MSD
Commencement: Jan 2003
Construction Value: $1,400,000
The objective of this
project is to design the replacement for a 1,300 foot reach of sanitary
trunk sewer adjacent to River Des Peres. The design considers the
staging of the pipe installation to facilitate continued service to
industrial and residential properties facilities during construction.
The depth of pipe
installation and associated spaced limitations due to proximity of
existing structures and facilities dictates the requirement for
tunneling a significant part of the new reach of pipe. ABNA will also
provide the boundary survey and strip map, topographic survey and all
easement and working room plats.
Deer Creek Flood Study
Client: U.S. Army Corps of Engineers
Completion Date: Jan 2002
ABNA performed hydraulic
analysis on a three (3) mile reach of Deer Creek, using new field
information and HEC-1 and HEC-2 computer software. There were four
bridges along this reach that were experiencing flooding and the study
was utilized to resize the openings of these bridges along the creek.

Fenton Wastewater Treatment Plant Improvement
Owner: MSD
Commencement: Jan 2004
Construction Value: $3,600,000
ABNA has begun
Construction Management work on a $3.6 million project to upgrade a
wastewater treatment plant in Fenton, Mo., for Metropolitan St. Louis
Sewer District.
The facility will have
the capacity to process 6.75 million gallons of sewage per day when
complete. The improvement will add two clarifiers, upgrade the aeration
system and install piping and instruments to expand the plant's
capacity. It will also add a biofilter to help control odor.
The upgrade will add 10
years to the life of the plant, which eventually will be eliminated when
the new Lower Meramec River treatment plant in Oakville is completed.
The project is part of
MSD's $647 million capital improvement and replacement program.
Harlem Baden Phase III
Client: MSD
Completion Date: Jan. 2003
Const. Value: $2,200,000
This project involved
performing a watershed study of the Harlem Baden area. Questionnaires
were delivered to ascertain the level of backup problems in the area.
The data collected was then analyzed and imputed into a GIS system. The
GIS data base was used to determine the location of the worst backup
problems and areas where I/I was evident when there was a major rain
event. The watershed area was then broken into 3 sub watersheds and the
combined sewer problems were then addressed with relief sewers and
addition of new inlets and manhole structures. Some pipe reaches were
lined to reduce inflow and Infiltration. A new detention basin was
designed to further reduce inflow from surface drainage into the
combined sewer system.
