Why Wastewater Management Is So Important?

By Jonny Blair


The life on this world is impossible without fresh water, as all living creatures depend on it. Statistics show that only 3 percent of the water in this world is good for drinking, but major part of it is in inaccessible regions or locked in ice caps. As a result, we can use only 0.08 percent of fresh water that should meet the needs or growing population for sanitation, drinking, manufacturing, agriculture, leisure and so on.

A recent study conducted in 2007 revealed that over 1.2 billion people around the world suffer from the water scarcity, and they do not have access to water enough to meet their daily needs. Another 1.6 billion of people suffer economically from the water scarcity, i.e. their local authorities cannot satisfy the rising water demand in these areas due to the insufficient investments or lack of human capacity.

Since half part of the world population is concentrated in the cities and urban centers, the natural water sources located around the cities are polluted by industrial and urban wastewater. The cities should develop systems for treating the wastewater; otherwise, there could be a risk for people's health related to the use of wastewater, containing different pollutants, such as heavy metals, pathogens, etc.

Because of the limited quantity of the fresh water, people have directed their efforts at water management and optimization of its use. In many areas, water comes in the form of harvested rainwater, so people should learn how to manage it efficiently. The rainwater is usually collected in barrels to be used in those periods when there is little or no rain and for agricultural purposes. The groundwater needs to be utilized as well. People drill wells and use this water both for drinking and agricultural purposes. People should also revive and manage lakes that can collect the water to make it accessible to the nearby residents.

The major consumer that uses up to 70 percent of freshwater resources is agriculture. The increasing world population requires more food. As a result the industrial and urban centers expand more and more, so the scarcity of water becomes a major issue in many regions around the world.

The water problem should be resolved globally by taking the following six important steps. However, each and every individual should consciously contribute to the water problem to be resolved.

First, we need to improve all water related data. Second, we should protect and treasure our environment, preventing further pollution. Third, water governance should be reformed. Fourth, the agricultural water use should be revitalized. Fifth, the urban and industrial water demand should be managed. Sixth, the women and poor people should have an access to the water resources and their management.

These steps should be taken globally to avoid water crisis that would be devastating for our world. All industries and urban centers need to learn how to use water efficiently, so that people can increase the water for agricultural purposes to meet the increasing demand for more and more food.
