Can you design a simple water filter using everyday materials? What would you include and why?
I can make a water filter using a plastic bottle, cotton, charcoal, sand and gravel. Cut the bottle, place cotton at the bottom, add charcoal, then sand and gravel. When dirty water is poured through, it filters out dirt and some impurities. Though not perfect for drinking, it shows how filtration wRead more
I can make a water filter using a plastic bottle, cotton, charcoal, sand and gravel. Cut the bottle, place cotton at the bottom, add charcoal, then sand and gravel. When dirty water is poured through, it filters out dirt and some impurities. Though not perfect for drinking, it shows how filtration works. This is a useful science activity to understand water purification basics.

(a) Keep the river clean
To keep the river clean, I’d ensure industries treat wastewater before release, build sewage treatment plants and enforce strict anti-dumping laws. Citizens would be educated on eco-friendly habits. Plastic use would be reduced and riverbanks cleaned regularly. Eco-clubs in schools and campaigns would involve the community. This would preserve aquatic life and ensure the river remains safe for all living beings.
(b) Prevent floods during heavy rains
To prevent floods, I would design the city with proper stormwater drainage and green spaces to absorb excess water. Flood-prone areas would have embankments and sandbag stations. Forested areas near the river would reduce runoff. A warning system would alert people early and emergency shelters would be built for safety. This ensures both human lives and animals are protected from flood disasters.
(c) Ensure there is always enough water for everyone, even during summers
To ensure water during summers, I would build reservoirs and promote rooftop rainwater harvesting in every building. Treated greywater would be reused in gardens and toilets. Water ATMs would provide access in public places. Laws to prevent water wastage, community storage tanks and educating citizens would make usage efficient. Groundwater recharge zones would be created to store water naturally and sustainably for year-round supply.

Tributaries are smaller rivers or streams that flow into a main river. In the case of the Godavari, these tributaries—like Indravati and Sabari—carry additional water that helps increase the Godavari’s volume and strength.

In the case of the Godavari, these tributaries—like Indravati and Sabari—carry additional water that helps increase the Godavari’s volume and strength. They support the river’s journey across many states, making it capable of serving human needs, wildlife habitats and agriculture along its long course toward the Bay of Bengal.

Godavari is a perennial river because it continues to flow throughout the year, thanks to regular rain in the Western Ghats and support from its many tributaries. This makes it reliable for drinking, farming and industry. In contrast, seasonal rivers depend entirely on monsoon rains and dry up during summer, which makes them less dependable for continuous water supply and human or ecological needs.
