How Rainwater Harvesting through Borewell Recharge can give you water supply throughout the year & can reduce your water bills
With the growing water insecurity in almost every country around the world, rainwater harvesting has become an essential activity for house owners. Apart from preventing water shortages, rainwater harvesting also helps House owners to reduce their water bills.
What is Borewell Recharge ?
Borewell recharging mainly focuses on utilizing surface or rooftop water that has been harvested and places where run-off water starts to percolate through Vee Wire Screen Filters. The water then passes through Vee Wire Screen Filters and percolates into the borewell. There are mainly two methods of borewell recharge which include direct and indirect recharge.
In the case of the direct recharge method, the percolation pit generally measures around 10 X 10 feet around the casing pipe of the tube well. This packaging pipe is then punctured with a drill machine and the openings are covered by a nylon network. The lattice doesn’t guarantee anything, however, the water goes across the borewell.
Presently the pre-projected concrete rings are put around the borewell packaging through which the reaped water would leak to arrive at seminararbeit schreiben lassen the nylon cross-section of the packaging pipe and multiplies into it through its openings. Around the casing pipe the Vee Wire Filter Screen is installed. The vacant region between Vee Wire Screen & RCC Rings is loaded up with separating materials like sand, rock, squashed stone, jam, and others. The downpour water from the adjoining water body, for example, a catchment lake is redirected into this well, it gets separated and afterward keeps on saturating the packaging pipe, hence topping off the drag well.
The direct bore well recharge method is however only recommended if the borewell has run dry and is not building any amount of water. Indeed, even a running borewell can ghostwriter rehearse direct re-energizing if there should be an occurrence of excess surface water which in any case would go down the channels and get squandered. However, letting unfiltered surface water saturate the ground is profoundly deterred as this might taint the groundwater or stop the spring with pollutants, for example, harmful minerals like fluoride and modern substance squander.
In addition to the direct recharge method, one can also use the indirect borewell recharge method. In this case, instead of digging up the pit around the casting pipe, it is dug within a radius of 20 feet and a minimum distance of 3 feet is maintained between the recharge well and the bore well. In the case of indirect recharge, the water first flows through the ground and then reaches the pipe. It then seeps in through the Vee Wire Filter Screen and casing pipe holes.
The indirect recharge method is found to work best for those bore wells which are functioning well and have not dried up completely. This is for ensuring that there is bachelorarbeit schreiben lassen continuous availability of surface water even during the dry seasons of the year.
Why is direct borewell recharge widely advocated?
The direct borewell recharge method is widely advocated as it helps in making the water available for both irrigation and drinking purposes. A well amount of water remains stored which can be easily used during the highly dry times of the year. Even the mostly dried-up borewells can also be filled up with direct recharge.
The method used for direct recharge is quite easy and the method of filtration is easy to understand for the general people. This is an environmentally friendly method and using this method also helps in preventing adverse social impacts like loss of agricultural land or displacement of population. Having direct recharge also helps in storing the surface water and minimizes the chances of water loss due to evaporation.
Groundwater is used extensively for both irrigation, agricultural, and domestic water supply which is resulting in a water crisis. At present, there has been a water crisis all across the world. The ancient civilization also flourished in the areas where there was abundant water. The need of the hour is to save water for survival.
Using the rainwater harvesting through bore well recharge not only provides water security but also helps in saving money. This method is cost-efficient as the water bills can be reduced to a significant amount using this method. The borewells remain charged with water throughout the year and they can be used throughout. The motor pumps for sucking the groundwater also do not have to be used and people can easily save a handsome amount of money from their electricity bills. In addition, water-saving aerators can also be added to the taps for reducing the wastage of water.
Groundwater is a common resource of water for all and all the apartments mostly draw it through the borewells. With the use of borewell recharge through rainwater harvesting, large quantities of rainwater can be sent underground. This will help in improving the groundwater levels of the locality. If these methods are implemented on a large scale, the groundwater level can be easily replenished and the water security will be guaranteed for all.
Before you take on Borewell recharge…
Borewell recharging undoubtedly is one of the best initiatives of 20th century. In order to extract 100% benefits of this process, certain pre-recharging research becomes inevitable
1. Aquifer Management
Some public initiatives of recharging the borewells goes ineffective due to lack of scientific understanding of groundwater. Before putting up with this process, one must have appropriate knowledge of the potential of their groundwater aquifer.
An approach called Aquifer mapping is a scientific method determining the quantity and quality of groundwater in a particular area. Aquifer mapping can help in
- Deciding the depth of recharge wells that can provide maximum recharge and maximum utilization of harvested water.
- Finding the recharge rate of an aquifer. This helps in deciding optimum number of recharge wells required for a given aquifer.
- Locating the natural recharge and discharge areas
- Defining how much water can be extracted and for how long.
2. Stream Pollution
Due to unchecked effluents from urban and industrial areas, stream pollution has become a matter of high priority. Measures must be implemented to ensure that the harvested water which is used for recharging the borwells must be free from water pollutants, especially in case of using a direct borewell recharge method. This is necessary to take care so that groundwater does not pose any health and environmental risks to the population.
3. Local legal framework
One must read and understand the legal regulations laid by central or state authorities for the area where recharging is intended to be done. This prevents unnecessary chaos and wastage of resources due to non-agreement.
