what are the advantages of rain water harvesting?

Answer 1

You can take bath at least 5 times a day.

Answer 2

Rain Water Harvesting is the best solution for our country's water needs. Apart from collecting rain water in the 'pit' people can also divert the bath room water,not sewerage,specially laundry water into the pit, which can be dug near the bore well.You can see the difference in a month or two. The water that percolates to the tube well will have no telling effect and definitely the yield improves. But make sure the collection pit is done properly with charcoal,small stones ,sand and pebbles. You can get help from the local authorities to dig out the pit. Lately all the states have made rain water harvesting MANDATORY before building is given a sanction.

Answer 3

Rainwater harvesting is the collection of raindrops. In most cases, a roof is used for this purpose. The rainwater then flows through the gutters, into a collection tank. The size of the tank is dependant of the amount and purpose of the water but also of the annual rainfall and the size of the roof.
The advantages of rainwater harvesting


Rainwater harvesting systems are integrated with the house which makes the water easily accessible.
Rainwater harvesting systems are personal which prevents arguments about who should take care of maintenance.
Installation costs are low; roughly some 250 US$ per system including a slow sand filter while sustainability of the construction is larger than that of a pump or wel.
The required skills are present in ANY community which makes adaptation easy.
The used materials can be kept simple, are obtainable nearly everywhere at local (low) cost price.
The construction is easy and cheap in maintenance.


Disadvantages of Rainwater Harvesting


The annual rainfall is limited to a minimum of roughly 2000 mm/year and should be spread in at least two (long) rain-periods of three months without total drought inbetween.
Cost per capita is higher for a rainwater harvesting system than for a communal pump or well.
Personal systems do not improve social activities (nor do they nessecarily spoil them).
Some kind of organisation, structure or retailer should be and stay present after construction to supply the users of spare parts and repair materials.

Answer 4

While I am not aware of How far is Rain Water Harversting is valid in European Countries/ USA or Japan , I will base what I say on the Indian Climate Conditions. In India , we receive a lot of Monsoon Rainfall. This Rainfall Amount is quite High in Southern India ,Maharashtra (esp. Mumbai ) , in Himachal Pardesh and Hills of Uttaranchal and lower ( but still considerable ) in Delhi,Haryana and North India . North-East India too has areas with considerable rainfall. What happens normally is that a lot of this Rainfall escapes to the Rivers and from the Rivers to the Seas . In earlier times , due to lots of Trees and Vegetation Cover , a lot of this water was absorbed into the Underground water and could be used by people from the wells , Tanks and other Traditional sources , such as Bawlis (Bao-Lis ) . But with havey depletion of Tree Cover and Increased Human Habitation , this water preservation has considerably reduced . This has lead to water shortages in large parts of the country .

Rain Water Harversting is a solution to this , where Pipes are provided in the Homes so that Rooftop water or water in Gardens around the Homes is taken to an Artificially created reservoir. This water can then be used for Lot of domestic Chores such as Washing / Bathing etc . And if implemented successfully in our country , it can be a good solution to the water problems ( at least for Non-Drinking Water )

Answer 5

Disadvantages Of Rainwater Harvesting

Answer 6

Rainwater Harvesting are of 2 types, according to me: (1) Pits 20 - 30 meters deep made in the ground for the recharge of the ground water. This way the Rainwater doesn't go waste in to the Sewer Drains and likes, but directly flows deep into the ground and gets stored there. So, you can say the water we draw and use through the Bore-wells gets filled back that way. (2) The Rainwater can also be stored in an Underground Sump, in our Homes, through the Terrace, through smart routing of the Piping and suitable Slopes. This way we can use the Rainwater for many domestic purposes.

Answer 7

as we know that underground water resources are drying out day by day so due to rain water harvesting we can store rain water under the ground for future use.

Answer 8

The more water people store from their roof for their own use, the less governments will have to build water storage reservoirs. Another advantage is that we don't have chemicals added to our water, it is fresh, clean and tastes sweet, it hasn't travelled through long distances of corroded pipes to get to us and we don't have to pay a water authority to maintain the system.

Answer 9

Increased rate of communicable disease transmission and increased concentrations of carcinogenic and toxic substances in the host consuming the water.

Rain water helps to carry the toxins, carcinogens, bacteria, and viruses from the air so that it is collected in people's rainwater storage containers.

Answer 10

Rain water, which goes waste, is saved and used any other time.
