Rainwater Harvesting Essay
Rainwater Harvesting Essay : Rainwater harvesting refers to the most popularly used method of saving rainwater. In other words, it is referred to as one of the most effective water management and conservation methods. People mostly living in arid and desert areas resort to rainwater harvesting for future management and conservation. Rainwater harvesting defines the processes whereby the precipitation that falls on the site is captured, stored and diverted. Based on the required use the rain goes through treatment. Furthermore, rainwater harvesting encapsulates water from the surface water runoff and this is mostly practised in the United States. The rainwater is subjected to surface water regulations. For a wide variety of uses rainwater harvesting can be done. These are potable uses such as irrigation, flushing the toilets, plumbing and vehicle washing. Moreover, it can be used for potable purposes such as cooking, washing, showering and as drinking water.
Components of rainwater harvesting
Rainwater harvesting includes multiple components that pass through various stages such as filtration, storing the water in the tanks for further reuse and transporting the water through the pipes and drains. The first component is catchments which is the surface that directly receives the rainwater and then it is provided directly to the system. The second component is the coarse mesh stage which is attached to the basement to impede the passage of the debris. The third component is the conduit which drains the rainwater from the rooftop directly to the harvesting system. The fourth component is the filter which is of two types the sand water filter and the charcoal water filter. With the help of this filter, the suspended pollutants from the rainwater are removed that is collected over the roof. Before the water reaches the storage tank, the dirt and debris are completely removed.
Advantages of rainwater harvesting
Rainwater harvesting can save the future paucity of water mainly in arid regions. In other words, it can help as an effective tool in educating people about the water conservation and management process. The various advantages of rainwater harvesting are listed below as follows:
- Rainwater harvesting helps in meeting the demands of water in times of crisis mainly during the summer season. In India, Tamil Nadu is the first state to have used rainwater harvesting. Moreover, rainwater harvesting is also used for non-potable purposes such as irrigation in the most arid areas.
- The water supplied by the municipalities is now being replaced by rainwater. Thus the former needs no longer to bear the burden of supplying water to the houses.
- Installing and designing rainwater reservoirs and collecting systems can help proving employment to people.
- Another benefit of using rainwater as potable water is that it does not have many chemicals as it is the most disinfected form of water, unlike the water tread with chloramines by municipal corporations.
Conclusion:
In conclusion, it can be said that rainwater harvesting is one of the most significant and effective ways of conserving and sustainable forms of managing water. In 1992, the US government enacted the US Energy Policy Act whereby it encouraged the method of rainwater harvesting. Thus, rainwater harvesting extends opportunities to acquire more water conservation gains in future.
