Rain Water Harvesting On Rooftop

The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel.

Rain water harvesting on rooftop.

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. 1 of rain on 1 000 sf roof will yield 623 gallons roof area m2 x precipitation amount mm amount collected liters other water conservation calculators. 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. To meet the increasing demands for water and to reduce the runoff.

It is important to control the decline of water levels and augment groundwater storage. The water is generally stored in a rainwater tank or directed to recharge groundwater. There are the following needs for the rooftop rainwater harvesting such as. Traditionally this involves harvesting the rain from a roof.

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. Roof material the material of the roof is not as important as contaminants that may be on the roof. Greenhouse roof has the highest collection efficiency most surfaces are a ok. Rainwater harvesting is collecting the run off from a structure or other impervious surface in order to store it for later use.

Dew and fog can also be collected with nets or other tools. This is a system of catching rainwater where it falls. For the vast majority of tank based rainwater harvesting systems the catchment area is the roof surface. 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.

While metal roofing or plastic sheeting e g. Roof area ft2 x precipitation amount in x 0 623 amount collected gallons easy formula to remember. There s just a short list of rooftop surfaces that rainwater harvesters should avoid. There are some important factors about the roof to consider when planning for a rwh system.

Rainwater harvesting is a technology used to collect convey and store rain for later use from relatively clean surfaces such as a roof land surface or rock catchment.
