Impacts of climatic events to wastewater infrastructure in recent years have highlighted the importance of planning for resilience. Orange County Sanitation District and Los Angeles County Sanitation Districts have performed assessments to identify climate threats, assess vulnerabilities, and develop resilience measures to adapt existing wastewater facilities to climate change. Coastal and inland facilities were assessed, including six wastewater treatment plants, sixteen pump stations, and collection systems. Climate threats considered in the assessments included flooding, sea level rise, tsunami, wildfire, extreme heat, extreme winds, and drought. The collection of climate threats, vulnerabilities, and resilience measures have been summarized in climate resilience plans, which provide a systematic approach for adapting existing infrastructure to climate change. Comparison of resilience plans for coastal versus inland facilities identified flooding due to sea level rise as the main climate threat for coastal facilities while wildfire, localized flooding, and extreme heat posed the greatest threat to inland facilities.

Track 2: Planning for Climate Resilience in Coastal and Inland Wastewater Systems

To lean into ASCE’s sustainability efforts to mitigate environmental effects and use resources wisely, ASCE’s International Conferences on Sustainable Infrastructure (ICSI) 2021 will be held as a virtual event. The dates of ICSI 2021 will be December 6-10th.

Powered by the ICSI Steering Committee based in Houston, the 2021 event will bring together leaders to discuss leveraging sustainable infrastructure for resilient communities.  The program will offer content from across the globe, but have several highlights on sustainability initiatives in Houston, Texas. We hope you will join us virtually for plenary sessions, technical discussions, along with opportunities for Q&A and networking, connecting with virtual exhibitors, and to earn professional development hours.
