Roof based rainwater harvesting.
The practice of collecting rainwater from rainfall events can be classified into two broad categories.
Dew and fog can also be collected with nets or other tools.
Using rainwater where appropriate conserves potable.
The image below shows how differences in roof slope do not change this building s catchment area.
Calculating your roof surface area building plans offer the easiest way to calculate your roof surface area after all the numbers should all be on there.
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.
Rainwater is collected from a roof like surface and redirected to a tank cistern deep pit well shaft or borehole aquifer or a reservoir with percolation.
Use this rainwater harvesting calculator to find the answer.
Rainwater harvesting rwh is the collection and storage of rain rather than allowing it to run off.
To calculate how much rainwater that you can harvesting use the equation below.
As your roof surface is the catchment area for harvesting rainwater it s important to know how large or small it is so you can calculate how much rainwater you can expect to harvest.
Rooftop rain water harvesting is the technique through which rain water is captured from the roof catchments and stored in reservoirs.
Collecting rainwater runoff from roof surfaces which usually provides a much cleaner source of water that can be also used for drinking is called roof based harvesting while collecting rainwater runoff from land surfaces is called land based harvesting.
From rainwater the practice of collecting rainwater can be classified into two categories such as.
Rainwater harvesting is an excellent means of supplementing water for use on site if the process is permitted by state and or local laws.
Land based rainwater harvesting occurs when runoff from land surfaces is collected in furrow dikes ponds tanks and reservoirs.
Wondering how much rainwater you could collect off your roof.
