India's sedition law has an interesting past. IPC was brought into force in colonial India in 1860 but had no section concerning sedition. It was introduced in 1870 on the grounds that it was dropped from the original IPC draft by mistake.

Water is the basic essentiality for us, and due to activities such as scanty rainfall and overpopulation, Rainwater harvesting is highly essential. Rainwater harvesting is the accumulation of rainwater for collecting, storing, and saving water to prevent water crisis and future use.
Rainwater is collected from the rooftop and is directed through tubes or pipelines into a storage tank to save the remaining water. Rainwater harvesting is of high quality and is a sustainable source of water.
Rain Water Filtration
Rainwater can be harvested or purified in multiple ways. The catch area before harvested must be cleaned thoroughly, and the pipelined must be flushed regularly. Initially, the water flow is diverted to wash or rinse the area.
Rainwater contains contaminants or other waste materials that affect the quality of the water. Contaminants such as dust, Bird excreta, pollution, leaves, and sand particles can affect water quality.
Filteration removes contaminants and other impurities and purifies rainwater for drinking and other purposes. However, the harvested water has to treated and tested before consumption to ensure the right quality check.
Industries use the practice of pre-filtration to ensure that the purified water is directed water to the tank. The pre-filtration measure is a vital step that the water supply system should not compromise in terms of water quality.
Some techniques of rainwater purification are solar sterilization, use of chemicals like iodine or chlorine, or sediment filtration. However, harvested rainwater used for drinking purposes can be filtered through Reverse Osmosis (RO).
Conclusion
Thus, several methods incorporate water purification. Rainwater used as drinking water must not be consumed without purification and filtration.

The main purpose of the rainwater harvesting is to use the locally available rainwater to meet water requirements throughout the year without the need of huge capital expenditure. This would facilitate the availability of uncontaminated water for domestic, industrial, and irrigation needs.
