WATER SCARCITY IN THE DEPOK AREA

Abstract

When the development of a city is very fast, the city can experience environmental imbalance
if the needs of the population are not met, especially clean water facilities. Depok City is a city that has
grown very fast, and only has a piped water channel to 20% of the community, so 80% of people depend on
groundwater. This will cause a disaster in terms of water scarcity. Through the calculation method of water
balance, analyzed based on the number and density of the population, the type and area of land use will result
in the total water needs of the people of Depok city to be balanced by the water supply through the pipeline
network of Depok City. According to the water balance of Depok city for 2010–2027, until 2017, Depok City
has been experiencing depletion of water supply from PDAM Tirta Asasta, and will then experience
increased supply in year 2022 because PDAM Tirta Asasta will increase its production capacity to be 2,285
L/sec with addition of supply from IPA Legong, Citayam, Duren Seribu, and Cinere up to a total of 3,475
L/sec. However, the condition of this supply will not last long, and will again revert to depletion in 2027,
caused by the need for clean water in Depok City increasing without a simultaneous increase in the
production capacity of clean water by PDAM Tirta Asasta.
