The Dekalb Sanitary District completed it Facility Plan Update in 2007. The plan identified the long range needs of the community, the rehabilitation needs of existing infrastructure and the regulatory issues facing the Disitrict. The adopted plan identified the need for agressive infiltration and inflow reduction program as well as rehabilitation of the existing wastewater treatment facility. These rehabilitation projects need to be completed prior to expansion of the sytem.
The DeKalb Sanitary District is moving forward with a phased rehabilitation program expected to be complete by 2017. The program is divided into three separate projects: biosolids, biological, and excess flow treatment. The Biosolids project includes rehabilitation of raw sludge handling, biosolids stabilization upgrades, the addition of sludge dewatering and storage capabilities. The rehabilitation project will improve the efficiency of the Disitrict's facility in multiple facets including reducing the biologigacil looad to the treatment process by minimizes recycle flows from the biosolids process.
Trotter and Associates, Inc. is in the processs of developing contract documents for the Phase I - Biosolids Rehabilition Project. The Design Phase will be completed in the Spring of 2009. The project will be funded through an Illinois EPA Low Interest Loan and is scehduled for construction from the Fall of 2009 through 2011.
The Village of Bloomingdale has been working with TAI to develop a plan to improve both the appearance and air quality at Village Hall. The Village was concerned about air quality within the lower levels of Village Hall do to the location of the air intake for the HVAC System. The air intake was located near the front of the building and occasionally became contaminated by fumes from vehicles parked in this area. Rather than redesign the entire ventilation system, the team developed a unique solution to the issue. The Village and TAI decided to extend the intake up to avoid exhaust fumes and other irritants. The new duct is located interior to a new chimney which is consistent with the architectural design of the building.
The project was designed in the Spring on 2008 and the Village awarded the construction Phase to Driessen Construction. The project will be complete in late 2008.
Trotter and Associates, Inc. is working with the City of St. Charles on rehabilitation of the East Side Lift Station. The lift station was originally construction in 1972 and last updated in 1985. The lift station serves most of the community east of 7th avenue and has a peak wet weather flow of 13.3 MGD. The project includes conversion of the existing lift station from a wet well/ dry well design to a submersible pump station. The lift station upgrades will include neW gates, mechanical screen, screenings compactor, pumps and controls. The design is expected to be complete in the early 2009 and out to bid in May 2009.
The Village of Port Barrington is located along the Fox River in McHenry County. Many of the homes adjacent to the river were originally constructed with private wells and septic systems. Over the years, high ground water and flooding has caused these septic systems to fail. The failing septics have had a negative impact on the water quality within the Fox River.
The Village of Port Barrington recEntly completed the Phase 1 Improvements which included construction of a low pressure sewer system to serve over 100 of the Village's homes. During a dedication ceremony held on August 8th the Village of Port Barrington honored U.S. Congressman Don Manzullo August 8th for his efforts in assisting the community to clean up the Fox River. Congressman Manzullo was responsible for drafting and championing a bill that held a line item appropriation which helped fund the project.
The Village will be pursuing additional funding to implement Phase 2 which serves the remainder of the community. The Phase 2 funding will be a combination of low interest loan and grants and is estimated to cost $2.0 Million dollars.
Trotter and Associates, Inc. has moved to its new corporate office. The office is located 5 miles west of Randall Road near the intersection of Illinois Route 64 and Burlington Road.
The office layout has been specifically designed around the TAI’s casual corporate environment with hardwood floors, exposed brick walls and wood beams – it will maintain the loft feel of the existing offices. These new facilities will allow TAI to continue to expand. Currently with a staff of 15 professionals, TAI's new offices will support up to 40 engineers, surveyors and technicians.

The City of St. Charles has awarded Trotter and Associates, Inc. the Vertical Control Network Project. This important project will result in horizontal and vertical control benchmarks throughout the community. A significant number of the benchmarks will be certified with the National Geodetic Survey. This control network will ensure that future projects throughout the community are constructed on the same datum.
The Village of Algonquin is expanding their existing Wastewater Treatment Facility from 3.0 to 5.0 MGD, with an ultimate design capacity of 8.0 MGD. This expansion and upgrade were the result of the community's successful strategic plan to attract high end commercial development to the area. The Village commission TAI to complete a Wastewater Master Plan in 2005. The Plan identified a series of collection system and treatment improvements as well as provided an implementation plan to achieve the Village's goals.
The wastewater treatment facility expansion included construction of biological nutrient removal process that will reliably achieve 5/5/3/1 (BOD, Suspended Solids, Total Nitrogen and Total Phosphorus). The upgraded facility includes Biological Phosphorus Removal with chemical polishing as well as a denitrification loop and second stage methanol polishing for total nitrogen removal.
The project was planned and design by TAI and HDR Engineering of Omaha, NE. The Village selected a ground breaking delivery method in Construction Management. IHC Construction has taken the lead and is acting as the C. M.
Trotter and Associates, Inc. and IHC Construction are completing the start-up of the Algonquin Wastewater Treatment Facility - Phase 6A. This phase increases the Village's capacity from 3.0 to 4.0 MGD. Phase 6-B is currently under construction and expected to be completed by June 08. Phase 6B will result in an overall increase to 5.0 MGD. Future Phases will increase the plants capacity to 6.0 MGD and ultimately 8.0 MGD
Trotter and Associates, Inc. has developed a Water Master Plan for the City of St. Charles. The Master Plan includes a comprehensive review of the existing infrastructure including water supply, treatment, storage and distribution system. In addition, TAI has updated of the City's WaterCad Model and is providing support to community development department in review of proposed projects. The recommendations of the Master Plan focus on defining long term needs, addressing water quality issues as well as capacity and pressure concerns. The recommendations include a Capital Improvements Program which will be implemented by the City beginning in 2008.
Trotter and Associates, Inc. provided planning, design and construction engineering services for the Village of East Dundee's Treatment Facility Expansion. The project expanded the Village's WWTP from 1.15 MGD to 2.30 MGD. The project was initiated by an intergovernmental agreement between the Village of East Dundee and West Dundee to provide for growth within the region. The $7.2 M project was funded through an IEPA Low Interest Loan. The project was constructed by River City Construction L.L.C., Hogan Contracting Corp. and Kadlec Electric. The Construction team achieved substantial completion on time and within budget.
The expansion incorporates biological nutrient removal capabilities utilizing a two three-ring oxidation ditches in conjunction with ORP and D.O. monitoring capabilities. The proper anaerobic. anoxic level is achieved within the outer ring of each ditch through the incorporation of VFD's on the aerator motors. The design also included tertiary clarification for enhanced settling capabilities and an upgrade of the UV disinfection facilities to include automated cleaning capabilities. All of which is intended to lower maintenance and operational costs as well as improve over plant efficiency. Ron Bockenhauer has report that the plant effluent is continuous meeting 2 mg/l BOD and 3 mg/l TSS.
Biosolids stabilization is achieved through aerobic digestion and was upgraded with an anoxic basin for alkalinity recovery as well as Kubota membranes for sludge thickening. This innovative use of membrane technology significantly improves the efficiency and stability of the digestion process. The process design includes a four stage digestion system operating in series. The concept of digestion in series alleviates concerns regarding recontamination of the stabilized biosolids. The first stage digester operates in conjunction with the anoxic basin and membrane basin in a continuous loop to removal water created during initial VSS destruction. The first stage digester is capable of achieving an estimated 30% VSS reduction at 20 Degrees C and 40% VSS reduction at 35 Degrees Celsius. Both waste activated sludge is introduced and permeate is withdrawn on a continuous basis, which is made possible through the implementation of the membrane technology. This design has significantly reduced the need for operator attention in comparison with the centrifuge thickening operations required prior to the expansion.
