Kerala, with its abundant rainfall, is an ideal place to implement rainwater harvesting methods. Rainwater can be harvested in two main ways: collecting surface runoff and storing rooftop rainwater. In this blog, we will briefly explore advanced rainwater harvesting methods using water storage tanks.
Harvesting Surface Runoff
Harvesting surface runoff is effective for urban areas. Here, rainwater flows over ground surfaces is collected in large storage solutions. This method involves using ponds, reservoirs and huge rainwater collection tanks to capture and store the runoff. Efficient harvesting systems and storage solutions ensure the collected water remains clean and available for use.
Innovating rainwater harvesting for space-efficient, sustainable water management
Rooftop Rainwater Harvesting
Rooftop rainwater harvesting is popular in Kerala, especially for households and schools. Rainwater is collected from the roof catchments of buildings, then diverted and stored in rainwater collection tanks. These tanks are equipped with filters, first flush devices, and overflow systems to keep the water clean and safe.
Importance of Water Storage Tanks
Water storage tanks and gutter pipes are central to rainwater harvesting systems. These tanks come in various sizes and materials to meet the specific needs of households and communities. Proper tank installation is crucial for effective rainwater harvesting. This involves placing the tanks strategically to maximize water collection and ensure easy access. Regular maintenance keeps the water clean and the system functioning efficiently.
Benefits of Harvesting Tanks
Harvesting tanks provide a sustainable way to collect and use rainwater. Households can lower their water bills and save on energy costs. The harvested rainwater can be used for various purposes, including Irrigation, household chores and potable uses (with proper treatment)
Direct Store and Use Method
In the direct store and use method, rainwater collected from rooftops is directed into a storage tank. The stored water can be used for non-potable purposes such as gardening, washing cars, and flushing toilets.
Embracing these modern methods of rainwater harvesting ensures a sustainable water supply. It also contributes to environmental conservation and cost savings. With the right water storage tanks and efficient systems, Kerala can make the most of its abundant rainfall.
