Water management explained simply means “water care” where water is being cleaned after using it and before injected it again to the environment. Water in nature is meant to be clean and fresh, and that is the way water ends it global natural cycle in the form of rain. 

Successful water management policies are not only essential for life on earth but it is imperative and should be composed of many dynamic key issues involving the effective removal of waste and pollution from joining the water cycle in all its stages. Waste and pollution management, public awareness, education, protection of water bodies and associated monitoring programs are typically carried out through major, strict and comprehensive national strategies, directives and regulations. These have to be in place all the time, anytime and everywhere, it is not a matter of being done now and then as the costs involved in rehabilitation are very huge and time consuming with complicated procedures and actions.

A typical case to illustrate is The Citarum River, indonesia, which is known as the dirtiest river in the world. The Roadmap for the rehabilitation of the river system is an extensive plan with many components and phases that is to be completed by 2023 at a total cost of $3.5 billion. This will be a huge undertaking by people and government of Indonesia for empowering communities to better plan and manage their water resources for a more sustainable future.
