Only one in ten of the poorest of Indonesia’s population have access to safely managed sanitation while 62 percent rely on unsafe drinking water. The United States and Indonesia will continue to improve water and sanitation services by helping at least 1.5 million people gain access to safe drinking water and one million to safe sanitation.

Access to clean sources of drinking water and adequate sanitation improves household health, makes cities safer and more climate resilient amid increasingly extreme seasonal weather fluctuations, such as heavy rains or droughts. The five-year USAID Indonesia Urban Resilient Water, Sanitation, and Hygiene (USAID IUWASH Tangguh) activity will help the Government of Indonesia advance towards the 2030 United Nations Sustainable Development Goals for 100 percent universal access to safe water and sanitation by increasing access to safe drinking water, sanitation, and hygiene (WASH) services for millions of vulnerable Indonesians.


Despite significant progress in access to improved water services and sanitation facilities over the past 20 years, Indonesia still faces challenges around insufficient drinking water, suboptimal sanitation products and services, and inadequate water resources management (WRM), particularly in poor and underserved urban areas. The $44.1 million USAID IUWASH Tangguh Activity will work with the Government of Indonesia, donor agencies, the private sector, nongovernmental organizations, service utility providers, and communities to strengthen Indonesia’s WASH and WRM sectors.

USAID IUWASH Tangguh will promote partnerships and provide technical assistance to the Government of Indonesia, private sector, and civil society to:

  1. Strengthen WASH and WRM sector governance and financing;
  2. Increase access for urban poor communities to climate-resilient, safely managed drinking water and sanitation services;
  3. Improve resources management so that drinking water provision remains resilient to climate change and weather patterns and is safely available throughout rainy and dry seasons; and
  4. Increase women’s participation in leadership roles that contribute to improvements in WASH and WRM. 

USAID’s IUWASH Tangguh activity will work at the national level and in ten provinces. The project builds on decades of USAID’s partnership in the WASH sector with the Government of Indonesia, the private sector, and other partners to improve access to safe water and sanitation services. The project will address climate-related risks, such as floods and droughts, and work to ensure climate risk data and response measures are factored into utility and local government water supply and WRM approaches.

Expected Results

Through partnerships, finance, and data, the USAID project will help at least 1.5 million people access safely managed drinking water and at least one million people gain access to safe sanitation services. USAID will work to build at least 50 public-private partnerships and reach at least one million people through campaigns promoting WASH and water resource management resilience. The project will also mobilize at least $310 million in domestic, regional, and international financing by brokering arrangements between utilities and new financing facilities to support new connections and water and sanitation infrastructure, including water treatment facilities and energy saving pumps.
