Dew and fog can also be collected with nets or other tools. There are some important factors about the roof to consider when planning for a rwh system. The good news is most roofing materials are suitable for rainwater harvesting. The rooftop rainwater harvesting is a method from which rainwater is captured from the roof catchments which is then stored in reservoirs and by adopting artificial recharge techniques to meet the household needs through storage in tanks harvested rainwater can be stored in the sub surface groundwater reservoir.

Rainwater from rooftop should be carried through down take water pipes or drains to storage harvesting system. There s just a short list of rooftop surfaces that rainwater harvesters should avoid. All components of a rooftop rainwater harvesting system should be made of chemically inert and non toxic materials to keep the water quality from being negatively affected by chemicals. Traditionally this involves harvesting the rain from a roof.

The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel. 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. Greenhouse roof has the highest collection efficiency most surfaces are a ok. Examples of such materials include wood plastic aluminum or fiberglass.

Roof material the material of the roof is not as important as contaminants that may be on the roof. Rainwater harvesting is collecting the run off from a structure or other impervious surface in order to store it for later use. While metal roofing or plastic sheeting e g.

Rooftop rain water harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs. Here s a handy little calculator to help you estimate how much rainwater can you harvest from your roof. Water from sloping roofs could be caught through gutters and down take pipe. 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.
