Changing for Climate Change: A study of vulnerability and adaptation planning for the Puerto Rico Aqueduct and Sewer Authority
Complying with the Governor of Puerto Rico’s Executive Order, the Puerto Rico Aqueduct and Sewer Authority (PRASA) completed both a Climate Change Vulnerability Study and Adaptation Plan for its entire infrastructure. PRASA is a public corporation of the Commonwealth of Puerto Rico, responsible for the production and distribution of potable water; and the collection, treatment, and disposal of a large portion of domestic and industrial pretreated wastewaters in Puerto Rico. The Vulnerability Study assessed PRASA’s infrastructure to identify potential climate change risks and impacts caused by five indicators or stressors: temperature, precipitation, sea level rise, hurricanes and tropical storms, and ocean acidification. The stressors that presented the most impact to PRASA’s water and wastewater infrastructure were: sea level rise, precipitation, and hurricanes and tropical storms. The Adaptation Plan analyzed all the climate change impacts identified in the Vulnerability Study and a set of actions and strategies (e.g. abandon, adapt, accept) to minimize their effect on PRASA’s facilities and operations were identified. Most of the actions focused on either adapting (mitigation) or abandoning the infrastructure (due mostly to inundation caused by sea level rise). The Climate Change Vulnerability Study findings and the strategies included in the Adaptation Plan serve as a roadmap for PRASA in its planning process and in its preparation towards the expected impacts of climate change in the near and not so distant future.
