Rain water harvesting on rooftop.

It is important to control the decline of water levels and augment groundwater storage. The good news is most roofing materials are suitable for rainwater harvesting. Dew and fog can also be collected with nets or other tools. Roof material the material of the roof is not as important as contaminants that may be on the roof.

For the vast majority of tank based rainwater harvesting systems the catchment area is the roof surface. Roof area ft2 x precipitation amount in x 0 623 amount collected gallons easy formula to remember. 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. There are some important factors about the roof to consider when planning for a rwh system.

The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel. Rooftop rainwater harvesting is used to avoid flooding of roads. Traditionally this involves harvesting the rain from a roof. Greenhouse roof has the highest collection efficiency most surfaces are a ok.

The water is generally stored in a rainwater tank or directed to recharge groundwater. This is a system of catching rainwater where it falls. Rainwater harvesting is collecting the run off from a structure or other impervious surface in order to store it for later use. There s just a short list of rooftop surfaces that rainwater harvesters should avoid.

Rooftop rainwater harvesting has been practiced for more than 4 000 years of human history and still remains necessary in many areas where there is no centralized water supply system or when quality surface water or groundwater is lacking sc 1. There are the following needs for the rooftop rainwater harvesting such as. Rooftop rainwater harvesting 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. To meet the increasing demands for water and to reduce the runoff.

Rainwater harvesting rwh is the collection and storage of rain rainwater is collected from a roof like surface and redirected to a tank cistern deep pit well shaft or borehole aquiferor a reservoir with percolation.
