### History and Progress of Wastewater Management in Asia

#### 1990s
In the 1990s, more than 240 billion cubic meters of industrial wastewater were discharged annually into the Yellow and Yangtze Rivers in China, causing heavy metal pollution with lead and cadmium. In India, over 100 million liters of untreated wastewater flowed into the Ganges River daily, affecting the health of approximately 400 million people living along the river. In the Philippines and Indonesia, untreated wastewater was directly discharged into the ocean, damaging marine ecosystems.

#### 2000s
In preparation for the 2008 Beijing Olympics, China significantly increased its wastewater treatment capacity, with facilities processing up to 3 million cubic meters per day. South Korea achieved a 50% wastewater reuse rate, focusing on industrial water recycling. In the Philippines, a facility with an annual capacity of 200,000 cubic meters was established around Manila Bay. JICA supported Indonesia in expanding wastewater facilities, while ADB improved sewer infrastructure in the Philippines.

#### 2010s
Shanghai began operating a wastewater treatment plant capable of processing 150 million cubic meters annually, improving urban water quality. In India, JICA supported enhanced wastewater management along the Ganges River. In Kathmandu, a facility was established with a capacity to treat 95,000 cubic meters of wastewater per day, meeting the demands of the rapidly growing city.

#### 2020s
With increasing water shortages and urbanization, wastewater reuse projects have become critical. Shanghai processes 1.7 million cubic meters of wastewater daily, using advanced technologies to remove heavy metals and chemicals. In Manila Bay, 50 million cubic meters of untreated wastewater flow into the ocean annually, severely impacting fisheries and tourism.

Veolia and BASF are driving projects in China and the Philippines to reuse 20 billion cubic meters of water annually. JICA and ADB aim to raise Indonesia's wastewater treatment rate from 14% to 20% by 2025, promoting sustainable water resource management across the region. These efforts are expected to improve water quality and protect the environment throughout Asia.
