Rainwater can be collected from the roof of a building, shed, or other structure. All rainwater harvesting systems should have four main components: (1) a collection surface; (2) gutters and a downspout; (3) a storage tank; and (4) an overflow system .

What are the objectives and components of a rainwater harvesting system?
Each rainwater harvesting system consists of three basic components ( Figure 3): 1 catchment or roof surface to collect rainwater 2 delivery system to transport the water from the roof to the storage reservoir (gutters and drainpipes) 3 storage reservoir or tank to store the water until it is used.
What are the factors of rainwater harvesting?
- The quantum of runoff.
- Features of the catchments.
- Impact on the environment.
- Availability of the technology.
- The capacity of the storage tanks.
- Types of the roof, its slope and its materials.
- The frequency, quantity and the quality of the rainfall.

What are water harvesting techniques?
A number of water harvesting techniques are based along contours including: contour ploughing; contour ridges; stone lines; grass strips and terraces . The technique used depends on the steepness of the slope, soil type, conditions, crops grown and other factors such as the availability of labour.
How do I switch from mains to rainwater?
A rainwater to mains water switch can be either automatic or manual: An automatic switching device detects when rainwater is low then switches to mains water. It typically uses either a float switch in the tank, or detects the tank water levels based on pump pressure.

Can you drink rain water?
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.
What is harvesting system?
A rainwater harvesting system comprises components of various stages – transporting rainwater through pipes or drains, filtration, and storage in tanks for reuse or recharge . ... Catchments: The catchment of a water harvesting system is the surface which directly receives the rainfall and provides water to the system.
How do you use a rainwater harvesting system?
The easiest way to harvest rain is through a rain barrel (make your own from a large trash can or an old drum) linked to a pipe fitted to collect rainwater from the rooftop and verandah of the house.To prevent the barrel from becoming a mosquito breeding ground, fasten a tight-fitting top to it, and screen the ends of ...
What are the short and long term water harvesting techniques?
Runoff harvesting for short and long term is done by constructing structures as given below. Contour Bunds: This method involves the construction of bunds on the contour of the catchment area (Fig. ... These bunds hold the flowing surface runoff in the area located between two adjacent bunds.
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 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.
Which one of the following is the benefits of rainwater harvesting?
Which one of the following is the benefit of rainwater harvesting? Explanation: Rainwater harvesting helps for flood mitigation . Appropriate designed recharges in open public spaces will help to keep the roads from flooding.
