Based on the annual costs of imported (purchased) water, pumping (energy), water supply infrastructure and borewell maintenance, wastewater treatment, human resources, rainwater harvesting maintenance, sinking fund (cost of replacement of infrastructure), this spreadsheet-based toolkit by Biome Solutions, helps calculate the total cost (in Rs/KL) of water.
This toolkit is designed for a urban residential layout and currently uses sample data from the case study on the work of the Rainbow Drive Layout Bangalore, and can be replaced with customised data.
