System Roof Top Rain Water Harvesting

There are some important factors about the roof to consider when planning for a rwh system.

System roof top rain water harvesting.

Greenhouse roof has the highest collection efficiency most surfaces are a ok. Rooftop rain water harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs. The good news is most roofing materials are suitable for rainwater harvesting. 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.

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. 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. Examples of such materials include wood plastic aluminum or fiberglass. While metal roofing or plastic sheeting e g.

There s just a short list of rooftop surfaces that rainwater harvesters should avoid. This is a system of catching rainwater where it falls. Water pipes should be uv resistant isi hdpe pvc pipes of required capacity. Rainwater from rooftop should be carried through down take water pipes or drains to storage harvesting system.

Dew and fog can also be collected with nets or other tools. 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. To use this calculator input the dimensions of your roof only area connected to rainwater harvesting system and the amount of rainfall in inches.

Here s a handy little calculator to help you estimate how much rainwater can you harvest from your roof. Rainwater harvesting is collecting the run off from a structure or other impervious surface in order to store it for later use. 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. Roof material the material of the roof is not as important as contaminants that may be on the roof.
