+# <p align="center">Rainwater Harvesting Calculator</p>
+
+## Description :-
+
+The Rainwater Harvesting Calculator is a web-based application that calculates the average annual rainwater that the harvesting tank can store (in liters) based on inputs fields such as:-
+ - height of the roof (in metres)
+ - width of the roof (in metres)
+ - Average annual rainfall (in mm) in the region
+ - Harvesting system efficiency (high , low ,medium)
+ - Storage capacity of tank (in litres).
+
+## Tech Stacks :-
+
+- HTML
+- CSS
+- JavaScript
+
+## Working :-
+
+-  The working is based on below formulas :-
+   1) area = length * width
+   2) totalRainwater = area * (rainfall / 1000) * efficiency * 1000
+
+## Screenshots :-
