Advantages And Disadvantages Of Rainwater Harvesting

According to the International Water Management Institute environmental research organisation global water stress is increasing, and a third of all people face some sort of water scarcity. Where demand exceeds supply and no effective management operates, there will be conflicts between the various players involved.

Water is one of the most precious resources, which support the life of almost everything in the world. Indeed, the world is covered by 75% water, but most of this water is not suitable for human consumption or use. On the same note, the world has been increasing its consumption of water due to the increasing population, leading to increased demands. The increased water consumption, which has been a result of high population, is worrying because the matter may lead to massive water shortages in the future.

The world’s supply of water is in steep decline as more and more is being used each year by more and more people around the globe. Currently, 800 million people do not have access to a drinking source. At the current rate, 1.8 billion people could be living in areas of absolute water scarcity by 2025.

Areas prone to flooding can be drained quickly or be unaffected, protecting thousands of families and government property from destruction. On the flip side, water shortages are plaguing states like California causing raging wildfires and public unrest. This system can ensure that people across the nation have a safe constant supply of water.

There is a water crisis which faces many parts of the world and it is a threat to survival of human beings since humans are primarily dependent on water. Shortage in drinking water is beginning to show its effects in first world countries, but is a current major problem facing lesser developed countries which have not taken drastic steps to harvest water and purify it to make it safe for human consumption. In developed countries the population growth has strained available water resources and stretched the ability of governments and private firms to provide safe drinking water to the vast majority of the population. Seventy one percent of

The most highlighted activity at the Southbank is rainwater system. Rain Bank stormwater harvesting project in South Bank Parkland, Brisbane is an important demonstration project for distributed alternative water supplies in Australia, providing an alternative solution for future issues and its highlight the profit and importance of having such solution. It has reduced the usage of main water supply, improves drought security and contributes to a cleaner, healthier waterways (Hamlyn,

Some areas of the world are already considered water stressed. In areas that are water stressed, the amount of sustainable water is running low. The people in these regions are in need of new and clean water to start being present. According to Roberts, “By 2050 more than half the world’s

Water, like food, is a necessity for human life that is used for many purposes such as agricultural, industrial, and domestic systems. While water is a common element around the world not all of it is clean and able to be consumed or used by humans. With only a percentage of the world’s water being clean and the use of water increasing, the availability of water around the world has become a common issue in the developing and even the developed world. This may be a smaller problem in areas close to clean water sources compared to areas far from a clean water source but, the availability of water is not strictly based on location, it also depends on the specific political and social needs and issues of the area as well. These all become issues that must be accounted for when deciphering whether water is a basic human right or a commodity and what action must be taken to aid the developing water systems in community’s that lack them.

You can collect rainwater on your own property as long as you do not dam up waterways that feed water reservoirs designated for public use. Water from your own roof can be collected till your heart's content. You cannot collect water deemed public water without the proper permits.

Storm water connects everyone to the same system and gives places with a limited supply of fresh drinking water a relatively

Refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning, manufacturing, and agricultural irrigation.

A new comprehensive study conducted by Dr Arjen Hoestra of the Netherlands’ University of Twente, demonstrates that water scarcity around the world is a getting worst than ever. Water shortage is becoming a global issue that may result in regional conflicts, economic losses and environmental risks.

Solving the global water crisis moves beyond the technical feasibility stage.(2011). Trends Magazine, (104), 19-24.

Less water means farming and other crops that need water to grow have lower yield. Water is needed to ensure food security, to feed livestock, and to conserve the biodiversity and environment.

It is an essential resource for sustaining life as well as central to agriculture and rural development, and is intrinsically linked to global challenges of food insecurity and poverty, climate change adaptation and mitigation, as well as degradation and depletion of natural resources that affect the livelihoods of millions of people across the world. According to the World Bank, (2010) report, water is a scarce resource with multiple interwoven uses that range from drinking water, energy, irrigation, manufacturing things, transport of people and goods among others. The report further states that, more than one-sixth of the Worlds’ population does not have access to safe drinking water, with 80% living in rural areas thus access to water cannot not be guaranteed globally.
