The problems

Clean water sources are usually disrupted by the use and misuse of water resources such as:

1. Agriculture. Wastage of water due to absence of good drainage on land that is irrigated with irrigation (for savings in the short term) which may eventually lead to loss of water and soil productivity.
2. Industry. Although the industry uses far less water than agricultural irrigation, but water use by industry may carry a more severe impact viewed from two aspects. First, the use of water for the industry are not regulated in the national water resources policy, the likely excessive. Secondly, the disposal of untreated industrial waste may cause pollution of surface water or groundwater, seihingga become too dangerous for consumption. Industrial wastewater is often discharged directly into rivers and canals, pollute it, and ultimately pollute the marine environment, or the waste is sometimes left to soak into the ground water source without any processing. Damage caused by these emissions is through the proportion of its volume. Many modern chemical contamination is so strong that little is enough to make water in a very large volume can not be used for drinking without any special processing.
3. Exploitation of water resources by households en masse.
The situation in urban areas is much worse than in areas where domestic sources are forced to care for underserved by makeshift toilets because of the scarcity of water, and septic tank emptying services booming due to unreliable, or simply by using other means that neither complete and unhealthy. This not only lead to problems for the users themselves, it is often dangerous to others and a threat to the environment because of their waste off without processing.

Due to lack of clean water.
The absence of clean water resulting in:

A. Diarrheal diseases. In Indonesia, diarrhea is the second largest cause of death for children under the age of five. As many as 13 million children under five with diarrhea every year. Contaminated water and lack of knowledge about clean living culture suspected to be the root of this problem. While Indonesia's 100 million people lack access to clean water.
2. Worms.
3. Impoverishment. Households that buy water from vendors to pay twice to six times the average monthly paid by those who have a connection to a private channel for only one-tenth the volume of water.

To improve environmental conditions and water that has been damaged, recovery efforts are required.
- Jointly disseminate water is vital, although the numbers remain, but the seizure of more and more. Hence the need for conservation, from simple starting from our own.
- Be selective in choosing products that use high water.
- Slowing the rate of run-off water.
- Do not throw garbage / waste on the river

To get healthy drinking water we can use solar water disinfection technology (Solar Water Disinfection)
Solar water disinfection is drinking water treated with the hot sun so that the water to be healthy and fit for human consumption.
In principle, solar water disinfection is done by drying the raw water in transparent containers for several hours to allow the heat generated together with UV (Ultra Violet) to kill bacteria in water.
