Planning for Climate Resilience in Coastal and Inland Wastewater Systems
Publication: Leveraging Sustainable Infrastructure for Resilient Communities
ABSTRACT
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, 16 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.
