If a client wishes to go forward with manual irrigation then what should be done for criterion 10 (GRIHA Version 3)? What measures can be taken by the landscape architect in this case?
If the project is not providing any irrigation facility then the project landscaping should demonstrate reduction of water for landscaping through reduced grass, plantation of local species etc.
The calculation can be done and checked for different cases in the online calculator. Only if the project is able to achieve more than 30% reduction, the criterion should be attempted.
