Carpentersville Aerator Building

In March of this year, a precast concrete Easi-Span building replaced a 50 year old redwood with metal siding structure at the Carpentersville, IL Water Treatment Plant.  Buildings are often looked at for what they contain, not for what they are.  In this situation, the building is an integral part of the aerator system which also consists of the filtration, ion exchange softening, chlorination and fluoridation.  The original aerator sat on top of a detention tank, and the new aerator had to be in the same location.  The 20′ x 20′ x 8′ Easi-Span building was placed on top of the existing concrete foundation, approximately 20′ tall.   McCann Concrete Products, a licensed Easi-Set producer, worked with project engineer Baxter & Woodman Inc. of Crystal Lake, IL and the general contractor Boller Construction of Waukegan, to accomplish the installation in just one day.  The existing aerator was installed in the 1960s and could not longer be maintained nor did it meet the needs of the growing village. The village wanted a replacement structure that was strong and long lasting.  A precast concrete building provided the right characteristics – a long lifespan, low maintenance, appealing appearance, cost competitiveness and ease of installation.

Easi-Span is a large clear-span all-precast concrete building system. The building has a simple broom finish texture on the exterior with a white concrete stain to match existing buildings. The roof consists of two Easi-Span building roof panels.  Customization is always an option and this one required very specific features. The structure required numerous air exhaust openings, air inlet openings and a steel entry hatch. In addition, an exterior flashing reglet was cast in the lower wall section, saving the contractor significant time and labor.  The project required locating and casting precise openings for existing equipment that remained in place during installation.
