【 摘 要 】

Lima is the capital of and largest cityin Peru, with an estimated population of about 10 millionpeople. SEDAPAL, Lima’s water utility, provides water tomost of the metropolitan region. While SEDAPAL is generallyable to meet the current needs of its customers and respondeffectively to most drought conditions that have beenexperienced in the past, it faces a number of challengesdoing so in the future. A rapidly growing population andexpanding city will likely increase demand. Currentlyavailable surface and groundwater supplies that SEDAPALrelies on are also just adequate to meet current needs.Changes in these supplies would challenge SEDAPAL’s abilityto manage drought conditions. This study evaluates theperformance of SEDAPAL’s current drought management planagainst future droughts and proposes augmentations. Thisstudy takes a deeper look into the operation of the system,the different triggers, other possible augmentations thanthose related to increasing supply. The audience of thisreport includes SEDAPAL and stakeholders from Lima as wellas other water managers and researchers interested in droughtmanagement planning methodologies and case studies. Thisstudy is novel, as it uses methods for Decision Making UnderDeep Uncertainty to explore uncertainty in near-term droughtmanagement conditions and identify drought managementstrategies robust to these uncertainties
