Disclaimer:
- Calculations are based on predictions using formulas. Actual results may vary depending on factors such as soil composition, infiltration well placement, local rainfall patterns, rooftop shape and material, shading structures, maintenance practices, and multi-level building designs. Since not all of the roof area can be included in the calculation due to potential structural limitations, shading, or multi-level designs, current water collection calculations use estimates to calculate recharge from both rooftop and ground surfaces.
- Users are encouraged to consult local experts or environmental data for more precise calculations
- Household:
- The calculation assumes that lower household incomes use smaller amounts of water, based on available research (source)
- Restaurant:
- The formula is based on the number of chairs and does not include water use by employees or other operational activities
- Hotels:
- The formula considers the number of bedrooms and pool capacity (if applicable) and does not include water use by employees or other operational activities
- Industry:
- Due to the variety of industries, a simplified formula is not provided. Users must input their average monthly water use for accurate results
