This total production capacity is divided into three smaller units. One of those is steel plate installation with a capacity of 2×100 L/sec, which was built in 2005. As one of drinking water provider, PDAM Rawa Lumbu is demanded to be able to provide safe drinking water that meets national water regulation PERMENKES 907/MENKES/SK/VII/2002.
