The government of countries where there is abundant rainfall should make rain water harvesting compulsory so that more number of people willingly come forward and participate in rain water harvesting. The world is facing a major water crisis in many different countries such as Africa and India where there is not enough water for drinking and fulfilling the daily needs such as washing and bathing. Rain water harvesting is the only solution to put an end to the water crisis that the world is currently experiencing. Many people do not realize and are yet to realize the importance of rain water harvesting and the numerous benefits that it has to offer mankind and nature. First of all, rain water is our primary source of ground water. It is from the ground water only that we get the water for our daily needs. So if we continue to use the ground water without giving the opportunity to  replenish it, then we will be in a very bad situation where we would not have enough ground water for the future generation to use. Hence it is advisable to indulge in rain water harvesting. To harvest rain water in our own homes, we can seek the help of water storage companies such as eco sac which has tons of experience when it comes to setting up of rain water harvesting facilities at homes, large buildings and other areas.
