Abstract : Life on earth is linked with water. Early human settlements date back to 5000 BC and people began to settle down near to water resources. This shows the importance of water for human community. In the present condition, about 1.1 billion population face scarcity of water and about 2.7 billion people face the shortage of water at least one month a year. Despite the fact that India has heavy rainfall, many parts of India face scarcity of water. The existing study shows that even though 60 percent of the rainwater can be conserved and utilised, only 20 percent of the rainwater is being utilised. The best method available to conserve rainwater is through harvesting the rainwater. From the study, we found that well recharging model is the most commonly used method of rainwater harvesting. Other methods like artificial storage tanks and rain pits have also been implemented. This project tries to make an impact study on the implementation of rainwater harvesting in Thrissur District of Kerala. The study sample has been chosen from three areas with varied terrain where rainwater harvesting was implemented. The effect of the change in water level was analysed using the tools percentage analysis, paired sample t-test and the statistical tool of one way ANOVA. After conducting the study, it was observed that rainwater harvesting has led to an increase in the water level. It was found that factors like terrain of the area or the type of rainwater harvesting method implemented do not have an effect on the quantum of change in water level after implementation of the system. The results of the study, implies that rainwater harvesting is the best suited method for houses and buildings to solve the problem of water scarcity
