BACKGROUND:
The Springbrook Water Reclamation Center (SWRC) biosolids storage building was built in 1992. The building houses biosolids produced from the treatment of wastewater from Naperville and Warrenville.
A structural assessment of the SWRC biosolids storage building was completed by Donahue & Associates in May 2018. Their recommendation was to clean and coat all minor corrosion on the surface of the building framing, wall grit, purlin connection bolts throughout the entire building bracing, and any minor panel rusting that was noticed inside of the building. This will be Phase 3, which will include the building from the floor to the ceiling where Phase 2 was completed. It will also include painting the two center trusses. Staff has used Garland/DBS Inc. for other painting projects and have a good working relationship.
The storage facility is essential as biosolids are produced continuously, but only land applied two or three times per year. At the SWRC, about 12,000 cubic yards, or 2,000 dry tons, of biosolids are produced per year, which is enough to fertilize about 350 acres of farmland. The nutrient rich biosolids meet guidelines for land application as fertilizer. Storing biosolids in an enclosed building protects the biosolids from weather to maintain the proper moisture content for land application, which is more cost effective and sustainable than landfilling. In addition, covered storage reduces the likelihood of odor complaints from neighboring homeowners. Phase 1 of the restoration/painting was completed in 2019 and Phase 2 was completed the following summer in 2020. This is the third of four total project phases.
