Know About Rain Water harvesting? Register to implement Rain Water Harvesting at your place
Water and managing its resources has been an important part of our efforts toward living a sustainable urban life. India has been blessed with abundant rainfall. However, various factors have been responsible for the erratic way in which receive our annual rainfall due to which the amount of rain that we receive is being perceived as insufficient. Coupled with rampant urbanization and the mushrooming of concrete cities, an important resource such as rainwater is being allowed to go waste.
Since its inception three years ago, Bluewiss has been providing solutions and know-how on efficient use of water and how we can utilize our water resources in a more effective manner so as to avoid the water crisis that we face every summer. Thus, we have been promoting the concept of harvesting rainwater to overcome our dependency on civic water supply during the harsh summer months.
Cost of Implementation
The cost of implementing a rainwater harvesting system varies from case to case. Some parameters that influence the cost of rainwater harvesting are:
How much rainwater to collect
Types of surfaces from where rainwater is collected
Existing structure and fittings for rainwater collection and flow
Type and capacity of harvested water storage device, if any
Method and system of rainwater retrieval for use from storage device
Here are some sample figures of how much rainwater can be collected from a given area:

Roof Area (A) 100 sq. m. Annual rainfall (B) 1000 mm =Approx. Annual Yield (A x B) 1,00,000 litres/year
Roof Area (A) 1000 sq. m. Annual rainfall (B) 40 inches =Approx. Annual Yield (A x B) 40,000 x 2.36 (constant) = 94,400 litres/year
Or use this simple third-party calculator:

1000 sq. ft = approx. 93 sq. m.
