Program Management Services for Detroit WWTP
As part of a joint venture with Jacobs, Wade Trim provided on-site program management
at-risk assistance to one of the nation’s largest, single-sited wastewater treatment
facilities over an eight-year period. The team rehabilitated and upgraded the City of Detroit’s
1.5 billion gallon per day plant to achieve sustained, continuous long-term regulatory permit
compliance. Nearly every treatment process in the plant was improved using delivery methods
that minimized each capital improvement project’s start-up time including pre-purchasing
equipment, early completion incentives, packaging projects, and design-build. More than 50
capital improvements totaling $224 million were completed while maintaining plant operations
and permit compliance.

Duck Key Wastewater Treatment Facility Upgrade
The Florida Keys Aqueduct Authority is working to upgrade their Duck Key Wastewater
Treatment Facility to meet Advanced Wastewater Treatment effluent limits by 2010 and provide
centralized service to Hawk’s Cay, Conch Key, and Duck Key communities. Two separate
treatment plants will be converted into a single treatment train and capacity will be
increased by constructing a second treatment train adjacent to the existing one. Treatment
quality, capacity, and operations will be maintained during construction using a
design-bid-operate-build process that requires the contractor to prove plant operability
and assume operations from 30 days prior to construction until 6 months after construction
is complete.

Genesee County District No. 3 Wastewater Treatment Plant Expansion
This $14 million expansion increased treatment capacity by 50% to accommodate growing demand
in three nearby communities. The design addressed operational, hydraulic and system problems
and enables the facility to meet restrictive summer effluent limits in their NPDES permit.
The expansion was constructed in four phases to minimize operational impacts and reduce costs.
The 22 MGD maximum flow plant features new preliminary treatment, additional secondary
clarifiers, a new ultraviolet disinfection, and improved solids handling and
biological treatment.

Ocean Reef Wastewater Treatment Plant Upgrade
With minimal on-site space for expansion, the North Key Largo Utility Corporation is upgrading their
Ocean Reef Wastewater Treatment Plant to membrane biological reactor technology to meet Advanced
Wastewater Treatment standards. This advanced biological nutrient removal treatment process will
produce a higher quality of effluent within the same approximate footprint. Existing aeration basins
are being retrofitted into a four-stage Bardenpho to achieve nearly complete biological nitrogen
removal and odor concerns will be addressed by covering treatment tanks.

EFSDS Pump Station Maintenance, Rehabilitation and Replacement Plan
The Evergreen-Farmington Sewage Disposal System’s (EFSDS) ten pump stations were evaluated during development of
a pump station maintenance, rehabilitation and replacement plan for the Oakland County Water Resources Commissioner, MI.
The plan will be integrated into the County’s ongoing development of an overall master plan for the EFSDS to
guide future capital improvement projects and maintenance activities. The pump station plan provides a template
for asset management that will preserve operational efficiency within the EFSDS and can be used at other critical facilities.

Palm Bay Water Resources Utility Management
The City of Palm Bay, Florida, developed a framework to meet its future wastewater and water reuse
needs. Three master plans were completed for water, wastewater and reuse, and design efforts are
underway to implement projects recommended including water main extensions, sanitary sewer
improvements and reuse distribution systems. In addition, a Computerized Maintenance and Management
System is being implemented throughout Palm Bay’s Utility Department to assist with asset management.

George W. Kuhn Retention Treatment Facility Improvements
New permit requirements to reduce the number and volume of CSOs from the George W. Kuhn Drain
RTF in Oakland County, MI, are being met as a result of facility improvements. The existing
facility was expanded from 90 to 120 million gallons per day and upgraded to increase its
volume and provide adequate CSO treatment. Wade Trim led electrical and flushing design,
and assisted with hydraulics, structural and mechanical design. A three-dimensional computer
animation was created to aid in the design and show operators how the facility would function.
In addition, a scaled model of the facility was built to calibrate the hydraulic computer
computations to accurately predict basin performance.
