The WaterPod will be collecting rainwater from a few of the impermeable roof areas. The calculations for collection are on this spreadsheet. There are three tabs feeding the results:
- Tab:Collection Calcs - Calculates the monthly availability of the rainwater.
- Tab:Collections Dimensions - Calculates the available rainwater collection area based upon the planned structures.
- Tab:Regional Climate Data - Show monthly rainfall from historical averages. Could be made more current.
