Jakarta Governor Basuki "Ahok" Tjahaja Purnama has revealed a plan to buy water springs in Purwakarta, West Java, and to construct a pipeline from Jatiluhur Dam in West Java to Jakarta to channel water.
The plan was discussed by Ahok and Purwakarta Regent Dedi Mulyadi, who visited City Hall on Wednesday. The governor said the plan to buy the springs was to ensure that Jatiluhur Dam had enough water to meet the needs of Jakartans.
"We want to buy springs that flow into Jatiluhur Dam to preserve the water," Ahok said at City Hall after meeting with Dedi. The governor said land to be bought by Jakarta included hectares of forests.
About 90 per cent of raw water that is treated in Jakarta comes from Jatiluhur Dam in Purwakarta, West Java.
Ahok said his administration would discuss this issue with the City Council so that the plan could be realised soon.
Meanwhile, the city administration has long planned to construct a pipeline from Jatiluhur Dam from Jakarta. Ahok said the project was scheduled to start next year and would be implemented by city-owned tap water operator PD Pam Jaya.
Jatiluhur Dam has the capacity to supply 19,000 litres of water per second, but 40 per cent of the water is lost while on its way to Jakarta through the Tarum Barat Canal, better known as Kalimalang.
Dedi welcomed the plan to construct a pipeline, saying it would significantly reduce water leakage. "Leakage is currently 40 per cent because we do not use a pipeline. If we use a pipeline, we can minimise the leakage to 5 per cent," Dedi said.
With the current supply arrangement, raw water flowing to Jakarta is also contaminated by various pollutants, such as domestic and industrial waste.
