Harvesting Rain Water Using Local Resources And Modern Day Techniques

The purpose of storing the rainwater is to meet requirements whenever resource goes out. With saved resources, you can use them in times of scarcity. You can use the harvested water for agriculture, home, industrial, and irrigation purpose. The natural way to set up rainwater harvesting is to grow fresh-flooded forests. With this method, you can save your expenditure and use unwanted lands.

Local Resource For Harvesting Rainwater

  • Rooftops

Setting up a rainwater harvester on the rooftop is a great option. Collected rooftop water can be used for various purposes. When a building has large rooftops provides a large quantity of water to its users.

  • Open Areas

Open areas like parks, open fields, landscapes, gardens, and many other pavements help collect more rainwater. More the quantity of water it can be used for large areas. It will be beneficial for those areas that have less rainfall.

  • Water Bodies

Ponds tanks and lakes are the best resources to collect the rainwater. Harvesting water will help meet people’s requirements for different domestic and industrial purposes. Also, help in leveling up the groundwater.

  • Water Drains

Areas where there is a stormwater drain, provide cost-effective and simple water harvesting as these storm drains contain water that can use for cleaning purposes. Also cost-effective because they are already built-in storm-prone areas.

Modern Techniques of Rainwater Harvesting

There are many different methods every county design their rainwater harvesting method suitable for them. Let’s discuss the most common modern techniques:

  • Ground Water Dams

The most common method of modern-day is groundwater dams. Groundwater dam’s feature is that the water is stored underground but not on the surface. When the water is stored underground, water evaporation is less than the evaporation on the surface. Therefore, when it is too hot, the water will not dry up fastly.

Parasites breed when water is stored on the surface, but another advantage of groundwater is that they cannot breed in underground water. There is also a subcategory of groundwater dams that are as follows:

  1. Sub-Surface Dam

The sub-surface dams are built to stop the flow of rocks and sediments that seep the surface water. In addition, it helps reduce the variation level of the groundwater as it can be built underground only.

  1. Sand Storage Dam

Sand storage dams are built above the surface of the ground. The particle of soil and sand travels when the flow of rain is high. So to sand storage, let all the sand store behind the dam and deposit clean water. When this sand storage is built, they evacuate all the sand, pass clean water to bedrock, and use it for sub-surface dams.

  • Ferro Cement  Tanks

Ferro Cement tank is another common method used to store rainwater. These are the containers that are cheaper than plastic tanks. The capacity of these tanks is 5000 liters. In addition, the fibro cement tanks can be constructed and repaired easily. The containers have been in use for 25 years and are the most convenient.

Tanks are pot-shaped containers requiring hessian cloth, GI wire, MS bars, and cement to build. The technology is simple to set up but needs skilled people to build these tanks.
