Query
We have noticed that the cost of peak hourly rainfall from IMD Pune is quite expensive and many clients refuse to pay the amount which then makes it difficult to size the rainwater system appropriately.
Could you please guide us on GRIHA accepted alternatives for peak hourly rainfall data.
Solution
Please refer to the attached journal for reference. Further, please let us know the city in which your project is located. We can try to help you out with the data accordingly.
