Sustainability in Water Management
On a global scale, sustainable water provides each person with affordable access to 20 to 50 litres of daily water required to sustain life. This is in accordance with the United Nations General Assembly recognition of “the right to safe and cleaning drinking water and sanitation as a human right that is essential for the full enjoyment of life and all human rights”.
Nations lacking freshwater has desalination an adequate water supply for many years. Yet, higher energy demands have challenged the adaption of desalination as a sustainable alternative. We continue to face real water crisis that can only be solved with sustainable consumption, promotion of clean energies, optimization of production processes and the use of recycled water.
In 2015, the United Nations (UN) warned that Earth will have water deficit by 2030 if it we do not change our current consumption habits.
A common approach to the challenge is to work towards setting up a balance in the use and supply of water. In simple terms to ensure sustainable water management the amount of water used should be less or about the same as the amount of water that is returning to the water source. It has been noted worldwide public water suppliers have taken active measures to reduce the use of water and help pay for keeping surface and groundwater supplies clean and plentiful by charging extra fees for increased water use. This encourages industry and people in their homes to conserve water. Many organizations also work to educate residents about the importance of a sustainable water supply.
The rapid rate of population growth increases the challenges of water and wastewater even more pressing —and it is potentially greater threats to peace and security.
Ensuring sustainability features in water supply, is to say, three-fold goals of economic feasibility, social responsibility and environmental integrity, is linked to the purpose of water use.
These purposes compete when resources are limited; for example, water needed to meet the demands of an increasingly urban population as well as those needs of rural agriculture. Sustainable water supply is a component of integrated water resource management, the practice of bringing together multiple stakeholders with various viewpoints in order to determine how water should best be managed. In order to decide if a water system is sustainable, various economic, social and ecological considerations must be considered.
