Rain Water Harvesting From Roof Top
The good news is most roofing materials are suitable for rainwater harvesting.
Rain water harvesting from roof top. Components of a rooftop rainwater harvesting system. Harvested rain water can be stored in subsurface ground water reservoir by adopting artificial recharge techniques to meet the household needs through storage in tanks. Rainwater harvesting is collecting the run off from a structure or other impervious surface in order to store it for later use. Rainwater harvesting differs from stormwater harvesting as the runoff is collected from roofs rather than creeks drains roads or any other land surfaces.
There s just a short list of rooftop surfaces that rainwater harvesters should avoid. While metal roofing or plastic sheeting e g. Calculating your water budget. Before you begin make sure that rain harvesting is legal in your area.
To give you an idea of how much water you have at your disposal for irrigation here is a simple equation for figuring out how many gallons your roof sheds when it rains. Rooftop rainwater harvesting systems are useful for augmenting the water systems in both urban and rural areas and they are excellent for use in arid and semi arid areas where traditional water sources are not readily available. This is the best and most effective method of harvesting rainwater for apartments as it is less expensive and if implemented efficiently helps in augmenting the groundwater level of the area. Rooftop rain water harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs.
The main objective of rooftop rain water harvesting is to make water available for future use. Rainfall data was collected from the jalja report. Dew and fog can also be collected with nets or other tools. Rainwater harvesting is the collection and storage of rain rather than allowing it to run off.
The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel. Greenhouse roof has the highest collection efficiency most surfaces are a ok. There are three basic components of a rooftop rainwater harvesting system. Its uses include watering gardens livestock irrigat.
Rainwater is collected from a roof like surface and redirected to a tank cistern deep pit aquifer or a reservoir with percolation. Traditionally this involves harvesting the rain from a roof. Roof size in square feet x annual rainfall in inches x 6. Rooftop rainwater is allowed to percolate in the ground and become helpful to increase ground water recharging groundwater aquifers.
Rooftop rainwater harvesting is one of the optimistic and economically viable methods of rainwater harvesting.
