It is important to know how people in Jakarta satisfy the need of clean water. They use ground water, the governmental water supply or PAM ( Perusahaan Air Minum ) and public hydrants. The number of the population in Jakarta is 8,5 million, but only 41% of them have accessed to clean water from PAM, while the rest still depend on ground water. The shallow ground water is used in hotels, offices, factories, and areas of residences. There won’t be any problem if they do not use the water more than the resource’s capacity.
Man is granted a large amount of colorless liquid called water. Life will not exist without water. There are a lot of domestic purposes as drinking, preparation of food and beverages, bathing, cleansing, and watering the lawns and gardens and secondarily in industrial processes, commercial products disposal of wastes in sewers, fire fighting, street sprinkling, swimming pools, and public fountains. For most of the purposes above the quality of water must be good.
There are a lot of sources of water supply such as underground and surface water. Ground water resources are near at hand and systems are cheap to install, i. e by setting a pump or digging a well. The surface water is obtained from large lake or river nearby, consequently it will be very expensive to get the water because the supply depends on the amount of water in large reservoirs, from which long pipes are needed to pump the water into the houses. Ground water is generally clear, cold, cold, colorless, and cleaner than surface water in some regions.
In order to have clean water supplies people should conserve the water. It can be conserved in many ways, including measurement and recording of all-purpose water consumption, holding flood water in o0versize reservoirs, desalting seawater and guard of ground water against the intrusion of seawater, and reducing evaporation in reservoirs using large ground water reservoir more extensively.
