Rainwater harvesting is a traditional water harvesting technique used in India to collect and store rainwater for various purposes, including drinking, irrigation, and groundwater recharge.

The primary objective of water harvesting is to increase water availability by capturing and storing rainwater or other water sources for future use.

Rooftop harvesting, gutter harvesting, and percolation tanks are all common methods for rainwater harvesting.

Check dams serve multiple purposes, including controlling soil erosion, storing water for irrigation, and recharging groundwater.

Rooftop rainwater harvesting offers several advantages, including reduced water bills, improved water quality, and increased groundwater recharge.

The primary function of a percolation tank is to recharge groundwater by allowing rainwater to infiltrate the soil.

Tanks, reservoirs, and dams are all traditional water storage structures used in India to store water for various purposes, including irrigation, drinking, and industrial use.

Reservoirs serve multiple purposes, including storing water for irrigation, generating hydroelectric power, and controlling floods.

Dams offer several advantages, including flood control, irrigation, and hydroelectric power generation.

Large dams can have several negative impacts, including displacement of people, environmental impact, and increased sedimentation.

Rooftop rainwater harvesting, groundwater recharge, and fog harvesting are all sustainable water harvesting techniques that can help increase water availability without compromising the environment.

Water harvesting and storage face several challenges, including climate change, population growth, and pollution.

The Indian government has launched several initiatives to promote water harvesting and storage, including Atal Bhujal Yojana, Jal Shakti Abhiyan, and Pradhan Mantri Krishi Sinchayee Yojana.

Community participation is crucial for ensuring sustainable water management, raising awareness about water conservation, and implementing water harvesting and storage projects.

Underground storage tanks, aquifer storage and recovery, and cloud seeding are all innovative water storage techniques that can help increase water availability.
