Indonesia is in one of the most geologically active regions in the world. The country is extremely vulnerable to a range of natural hazards including floods, earthquakes, volcanic eruptions, landslides, and tsunamis. The World Bank estimates that at least 110 million people in 60 Indonesian cities are exposed regularly to such hazards, which are leading to significant disaster events more frequently due to the effects of climate change and inadequate risk mitigation strategies. Despite such disastrous events and negative impacts on communities, most water supply infrastructure in Indonesia has not been designed to be resilient against, and cope adequately with, disaster events. In disasters, water supply services are sometimes disrupted for weeks, due to destroyed pipe infrastructure and water treatment facilities and thus reducing the quality of drinking water. Even where the water supply system is left intact, there is a high risk of contamination from sewage or seawater brought by the tsunami. Flooding events have similarly is rupted water supply and contaminated water sources.
The overarching goal of this consultancy assignment was to provide advisory services and technical inputs to increase awareness and capacity of relevant Government of Indonesia line agencies, AKATIRTA (tertiary education institution in Indonesia that creates environmental engineering professionals specializing in water supply and sanitation) and water supply service providers in developing disaster risk management and climate adaptation plans for water supply infrastructure, particularly to address seismic and hydro meteorological (floods, droughts and landslides) risks.
