Storing water underground is environment-friendly. The ecological benefits of rainwater harvesting are immense. It minimizes the impacts of flooding by funnelling the off water into large tanks for recycling and helps reduce the load placed upon drainage systems. It reduces soil erosion and flood hazards by collecting rainwater and reducing the flow of stormwater to prevent urban flooding. This increases the productivity of aquifer resulting in the rise of groundwater levels and reduces the need for potable water.
Rainwater harvesting is the collection and storage of rainwater for reuse on-site, rather than allowingit to run off. This water can be used for various purposes such as gardening, washing, transportation, drinkable with filtration etc. In urban area rainwater flows away as surface runoff. This runoff could be caught and used for recharging aquifers by adopting appropriate methods. Rooftop rainwater harvesting is a system of catching rainwater where it falls.
In rooftop harvesting, the roof becomes the catchments, and the rainwater is collected from the roof of the house or building. It can either be stored in a tank or diverted to artificial recharge system. This method is less expensive and very effective and if implemented properly helps in augmenting the groundwater level of the area. This blog gives the ideas to store rainwater and utilise effectively from our day to day routine life.
