Municipal water networks are vulnerable to disaster events like earthquakes, flooding, pollutants and water shortages caused by drought or poor management. With a rainwater system a home or community can capture and collect water suitable for drinking, cooking and gardening even during periods where there is insufficient rainfall to satisfy the public water network. Other benefits cited by the collection of rainwater include reducing expense (in regions where water supply is not free), lowers local demand on freshwater resources, reduces risk of flooding in low-lying areas and slows erosion in dry environments<ref>https://www.treehugger.com/beginners-guide-to-rainwater-harvesting-5089884</ref>. Water is typically captured from a sloped roof, but it can also be captured from a structure deliberately built for the purpose. | Municipal water networks are vulnerable to disaster events like earthquakes, flooding, pollutants and water shortages caused by drought or poor management.

== Rainwater collection calculator == | |||
'''Formula''' | |||
The formula to calculate the rainwater collected (RC): | |||
RC = A * R * C | |||
Where: | |||
RC: Rainwater Collected (in liters or any desired unit) | |||
A: Collection Area (in square meters) | |||
R: Rainfall Intensity (in millimeters per hour) | |||
C: Collection Efficiency (expressed as a decimal or percentage) | |||
'''Example in metric''' | |||
Suppose you have a collection area of 60 m², a rainfall intensity of 10 mm/h, and a collection efficiency of 65% (0.65 as a decimal). Using the formula: | |||
RC = 60 * 10 * 0.65 = 390 liters | |||
390 liters of rainwater can be collected in this scenario. | |||
