How does it work?
SimTanka analyzes rainwater harvesting systems with covered rooftop tanks using a simple mathematical model. It factors in the size and nature of the collecting surface, storage tank capacity, and daily water demand. By simulating real-world rainfall patterns over five years or more, it estimates your system's reliability and suggests strategies to meet your water needs reliably.
Features
- Downloads the past daily rainfall records for your location and displays them. Powered by Visual Crossing Weather.
- Allows you to set your daily water budget.
- Uses your water budget and the past daily rainfall records to suggest optimum tank sizes.
- Helps you plan for water shortages and droughts by estimating the amount of water available in the next thirty days.
- Allows you to keep a water diary to record the amount of water harvested, potability of water, and a log of maintenance.
Thanks
- The development of SimTanka was made possible by the unwavering encouragement and support of Janaki Abraham.
- The mathematical model employed by SimTanka relies on the historical daily rainfall records specific to the location of the rainwater harvesting system, with these crucial rainfall data being provided by Visual Crossing Weather as part of their support for open-source projects.
