A bit about Cikapundung
• Rainfall: averagely
2300 mm/annum
• Role: water supply
for 300,000 ha of
rice fields; nearly
2.5 million
population (in 5
major developing
areas); small
electricity power
plant (3.150 kW).

Gaps: quantity vs quality
• Water quality decreases as the
river flows deeper into the city.
• Contaminations: heavy metals,
nitrates, and organic
substances.
