.As mentioned above, to see that. Water is important and useful loads. We should help the sewage treatment or loss of water resources by water conservation:
1.Use it sparingly. Water use efficiency in addition to the cost of the water down. The water dropping down the water quantity is less. And prevent water shortage by
2.Conservation of water use. In some seasons, or in the presence of water, waste water should be related to use, such as the storage tank water, creating in the jar. Dredging, including creating a reservoir. Irrigation systems and
3.Development of water resources in some areas that lack water. Necessary to find the water more. In order to be able to have water to use.
