It is better to collect rainwater in ponds or artificial lakes as,it will take a lot of time to recharge the groundwater .It is a faster process , lot of water is collected in ponds and lakes as it rains for a long time.The water will directly fall in the ponds or lakes , without building any additional pipes.A lot of water can be stored in ponds and lakes.
