Comparison of conventional rainwater harvesting systems with KFP RWH system : Varshajal

Rainwater Harvesting Systems - a Comparison

Advantages of KFP rainwater harvesting over conventional RWH systems

Huge Evaporation Losses
Occupies land of farm
Storage capacity 10-15% rainfall
Life is 10 years
Silt deposition
Electricity is required

Need Stream/ Nullah
Life is just for 1 year
After that sand filled woven plastic bags start wearing and flows away
The plastic bags add to the pollution

Huge land is submerged
Causes displacement of people.
Huge Evaporation Losses
Cannot supply water for irrigation due to Urban demand for water.
Cannot irrigate even 2-3 times of submerged land
Percolation stops within 3-4 years due to silting.
Huge Electricity is required

Needs filteration
The acquifers in the well gets clogged
Through direct recharge, silt can enter water
Can harvest only 5 - 10 lakh ltr. rainwater

Harvests 80% rainwater underground
No evaporation /run-off losses
Huge storing capacity
No wastage of Land
Life more than 200 years
No silt deposition
Water available through out the year
Eco-friendly solution
Saves irrigation power
