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.
What are the objective of rainwater harvesting?
The main objectives of rainwater harvesting are
Reducing loss of water by its running –off. Avoiding flooding of roads. Meeting the demands of increasing water. Reducing groundwater contamination.
What are the main objectives of rainwater harvesting class10?

What are the two main techniques of rainwater harvesting?
There are two ways of harvesting rainwater, namely; surface runoff harvesting and rooftop rainwater harvesting.
What are the qualities of rainwater?
Rainwater is slightly acidic and very low in dissolved minerals; as such, it is relatively aggressive. Rainwater can dissolve heavy metals and other impurities from materials of the catchment and storage tank.
What are the ways to conserve rainwater?
Tips for Managing the Quality of Saved Rainwater
- Regularly clean your roof or gutters to reduce contamination from dust and bird droppings.
- Use a simple filter to prevent debris from entering the barrels or cisterns.
- Quickly cover or use water collected in containers to prevent mosquitoes from breeding.
What is water harvesting and its techniques?
Water harvesting techniques gather water from an area termed the ‘catchment area’ and channel it to the cropping area or wherever it is required. Conservation techniques conserve water within the biomass and the soil by reducing run-off and keeping the water where it falls, as much as possible.
What is rainwater harvesting explain with diagram?
Rain water harvesting (RWH) is a technique of collection and storage ofrainwater into natural reservoirs or tanks, or the infiltration of surface water into subsurface aquifers (before it is lost as surface runoff). One method of rainwater harvesting is rooftop harvesting.
What are the benefits of drinking rainwater?
It contains alkaline pH, which has detoxifying effects and also promotes a healthy digestion. The toxins and free radicals we ingest and absorb every day make our blood more acidic. Rainwater, with its alkaline pH, helps to neutralize our blood pH, thus helping to make our body function in a more efficient manner.
What bacteria is in rainwater?
Pathogens found in rainwater include members of genus Campylobacter spp., Salmonella spp., Shigella spp., Vibrio spp., pathogenic E.
Is rain water safe to drink straight from the sky?
Safety of drinking rainwater
There is nothing inherently unsafe about or wrong with drinking rainwater, as long as it’s clean. In fact, many communities around the world depend on rainwater as their primary source of drinking water. That said, not all rainwater is safe to drink.
