In areas where water supply is problematic or water resources are scarce, rainfall collection is a good solution. Reduce the use of treated municipal water for uses such as gardening, lavatory and laundry; Reduces the need for well drilling; And it reduces the maximum volume of storm water.
Rainwater harvesting can provide potable water for a small community. Especially when pipes are too expensive to install and a central well or pump can not be used all year round, a rainwater collection system is a viable solution.
Some advantages of rainfall collection:
• Easy access
• Installation costs are low, with easy construction, low cost materials and cheap maintenance
• Sustainability is greater
• Easy adaptation to different types of communities
