System Roof Top Rain Water Harvesting

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.

System roof top rain water harvesting.

Greenhouse roof has the highest collection efficiency most surfaces are a ok. Traditionally this involves harvesting the rain from a roof. 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. Water from sloping roofs could be caught through gutters and down take pipe.

The rain will collect in gutters that channel the water into downspouts and then into some sort of storage vessel. There s just a short list of rooftop surfaces that rainwater harvesters should avoid. 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 use this calculator input the dimensions of your roof only area connected to rainwater harvesting system and the amount of rainfall in inches.

For the vast majority of tank based rainwater harvesting systems the catchment area is the roof surface. Rainwater from rooftop should be carried through down take water pipes or drains to storage harvesting system. 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. Rainwater harvesting is collecting the run off from a structure or other impervious surface in order to store it for later use.

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. The good news is most roofing materials are suitable for rainwater harvesting. This is a system of catching rainwater where it falls. Examples of such materials include wood plastic aluminum or fiberglass.

There are some important factors about the roof to consider when planning for a rwh system. Roof material the material of the roof is not as important as contaminants that may be on the roof. Here s a handy little calculator to help you estimate how much rainwater can you harvest from your roof. Water pipes should be uv resistant isi hdpe pvc pipes of required capacity.
