Do not let precious rain water simply flow into your drains! Use this RWH Calculator now, and see how much water and therefore money you can save by making efficient use of rain water. There are just a few necessary steps to take. From the integrated database (from National Hydraulic Research Institute of Malaysia, NAHRIM), the averaged precipitation is determined for each location in Malaysia. You simply select the location; specify the type of roof, the roof area, the amount of first flush, usage and the cost of treated water in your locality. Even if you are not located in Malaysia, it's not a problem! You can always input the average annual rainfall figure manually and continue with the calculation.

Based on these data, the maximum possible savings in water and money are calculated. With a slider you can view the development of the savings for a period from 1 year up to ten years. Your RWH system capacity is displayed and the system is cross checked – the resulting balance between rainwater collection and usage is clearly presented on a bar scale for easy understanding. In Auto mode, RM4.50/m3 is used as the total cost of treated water in Malaysia (USD1.50/m3 for everywhere else).

You'll be amazed at the potential of rainwater harvesting on your wallet.
