Beneath the Streets: New Tools for Managing Degrading Sewer Infrastructure

Description
Infrastructure degradation is a chronic problem for fats, oils, and grease (FOG) pretreatment programs at wastewater utilities, which can lead to harmful bypass and high loss of a renewable energy feedstock.

Infrastructure degradation is a chronic problem for fats, oils, and grease (FOG) pretreatment programs at wastewater utilities, which can lead to harmful bypass and high loss of a renewable energy feedstock. Not only does this exacerbate the potential for environmental harm, but not taking advantage of this resource leaves most FOG anaerobic digestion programs non-resilient and non-scalable. It is vital that there are strategies utilizing a sustainability perspective and integration of hard and soft infrastructure management principles to address this infrastructure degradation issue before there can be fully implemented zero-waste, FOG resource recovery initiatives. This applied project sought to answer the question, “How can municipalities sustainability manage the issue of degrading FOG pretreatment infrastructure?” with an emphasis on providing an applied example where a sustainability approach can mitigate complex, infrastructure problems. In partnership with the City of Tempe’s Environmental Services Section, this project addressed the issue of degrading infrastructure by crafting and implementing a comprehensive Infrastructure Assistance Program (IAP). Designed to assist food service establishments (FSEs) and wastewater utilities, the IAP provides pathways for preventing FOG infrastructure degradation through initiatives that bolster hard and soft infrastructure to support a more efficient means of achieving compliance and local goals for resource recovery and renewable energy.

Arizona State University had established a set of institutional sustainability goals of which Circular Resources or zero waste was one. The university currently has an established department and subsequent programs and initiatives to drive success towards university wide zero waste, however there was still opportunity for growth to help the university achieve the goal. This paper examines the process taken to assess organizational conditions used to justify the implementation of a new engagement strategy to advance the Circular Resources/Zero Waste goal. Readers should walk away with an understanding of how to translate this same process into other organizational structures.
