Water Resource Management: Onsite Water Reuse for Universities & Campuses

In addition to water scarcity, drivers to consider water reuse now include aging or inadequate infrastructure, resiliency, resource recovery, green-building initiatives (LBC/LEED) and increasing costs for conventional water and sewer. Onsite or distributed systems are located closer to the source and point of use making it more efficient to recover and reuse both the water and embedded energy.  

Case studies will be reviewed including The New School University (NYC) and the redevelopment of Microsoft’s Silicon Valley campus (Mountain View, California). The New School University represents an urban academic application of direct non-potable water reuse within the University Center. This system requires a very high level of treatment in a very small footprint with membrane bioreactor (MBR) technology for flushwater, cooling and laundry reuse. The Microsoft campus incorporates a wetland treatment system that addresses the Living Building Challenge water petal objectives for non-potable water. These projects are a testament to the evolution of distributed systems over the last few decades including changes in regulations, technology and project delivery methods along with the integration of our water and energy infrastructure. This presentation will focus on drivers for these projects, benefits, key challenges, lessons learned, financial drivers/solutions and a discussion as to how the elements of these projects can be replicated at other universities and campuses.

Participants will learn how these approaches can:
• Reduce total water consumption by 50 to 95% and 100% non-potable water use reduction along with associated application to the Living Building Challenge process
• Reduce wastewater discharges and waste loads by 60 to 100%
• Reduce environmental impacts from Combined Sewer Overflows
• Reduce nutrient and chemical loads to water bodies
• Incorporate energy recovery with economical operations that uses the waste as a resource, provides treatment at the source and yields a favorable Life Cycle Cost and Life Cycle Assessment.
