The Greater peoria Sanitary District assumed ownership of an existing wastewater treatment facility built in the late 1970's when a subdivision, which had previously owned the facility, annexed into the District.  At this point, the District became responsible for the proper operation and maintenance of the wastewater treatment facility, which was in desperate need of repair due to its age and years of neglect.  Rather than dedicate time, money and personnel to the facility, the District decided to build improvements to their existing collection system which would bring all wastewater flows from the development to their main facility for treatment.  Maurer-Stutz, Inc. was retained to design a new sanitary sewage pump station and force main.

The sanitary sewer improvements included the following: a trunk sewer to bypass the existing wastewater treatment facility and provide sufficient capacity for future development; duplex submersible pump lift station, a split-face masonry control building; sewage force main; bituminous access road, rehabilitation and/or relocation of existing sewers within the subdivision, and decommission of the wastewater treatment facility.  The project included a 730 gpm duplex submersible pump lift station, 6,100 feet of 12" sewage force main, 600 feet of 18" gravity sanitary trunk sewer, 900 feet of a 12 feet wide bituminous access road, and a 900 square feet concrete masonry unit control building.

We were chosen by the City of Canton to design improvements to their combined sewer collection system.  The existing Kilroy Sewage Pumping Station was constructed in 1975 to handle sanitary sewage as well as large volumes of combined sewage.  Thirty years of operation, coupled with station flooding from a nearby tributary to Canton Lake have resulted in a pumping station requiring much attention and maintenance.  In addition, the station was no longer in compliance with current regulatory requirements.  Maurer-Stutz, Inc. was retained to design a new combined sewage pumping station that is cost effective, safer for City personnel, and in compliance with today’s more stringent regulations.

The pumping station improvements included the following: a mechanical bar screen with emergency by-pass to capture large debris from upstream combined sewers; submersible pump lift station with four pumps to handle both dry weather and wet weather flows with a maximum pumping capacity of 3,000 GPM, a control building housing a motor control center, pipe gallery, and 550 KW emergency generator; a site constructed completely above the 100-yr flood elevation; bituminous pavement around site; and security fencing. 

Maurer-Stutz, Inc. was retained by the City of Pekin to assist the City in its efforts to improve the capacity of the wastewater collection system.  Through the development of a Comprehensive Plan, the City recognized a high probability for development to the north and east of the City, property which did not, at the time, have sanitary sewer service.  Our team worked closely with City personnel during the planning phase of the project to not only develop the most cost effective design, but also to develop a design that would maximize the benefit to the community.  Maurer-Stutz, Inc. was retained to provide planning, design and construction phase services for the new facilities.

The wastewater collection facilities were designed to handle wastewater from short term development as well as from long run future development in the defined project area.  The wastewater collection system improvements included: a large diameter interceptor sewer, a duplex submersible pump lift station with controls and emergency generator, telemetry capability, sewage force main, bituminous access road, three bore and jack operations, and several creek stabilizations.  Numerous easements and land acquisition were also important components of the overall project.
