About the Water Wise Household Water Calculator
The Water Wise Household Water Calculator is an easy-to-use educational tool designed to help households better understand their daily water consumption, estimated monthly water costs, and opportunities to save water.
By answering a series of simple questions about household size and everyday water-use activities, the calculator estimates your household's water consumption and compares your results with Water Wise recommendations and national water-use benchmarks. It also provides practical suggestions to help reduce water consumption, lower municipal water costs, and promote more sustainable water-use habits.
Whether you are a homeowner, tenant, student or educator, the calculator is designed to raise awareness of how everyday actions can make a meaningful difference in conserving one of South Africa's most precious natural resources.
Important Information
- The results are estimates only and are intended for educational and awareness purposes.
- Actual household water consumption will vary depending on individual behaviour, plumbing fixtures, appliances, property size and local conditions.
- Estimated monthly costs are based on the selected municipal water tariff and may differ from your actual municipal account.
- Municipal accounts may also include fixed charges, sanitation charges, wastewater charges, refuse removal, VAT and other service fees, which are not included in this calculator unless specifically stated.
- Municipal water tariffs are updated periodically. Users should refer to their local municipality for the latest approved tariffs.
- The Water Wise Score and Household Benchmarking are intended as guidance to help households identify opportunities to improve water-use efficiency and should not be regarded as an official assessment of water consumption.
Every drop counts. Small changes in daily water-use habits can make a significant difference to conserving South Africa's precious water resources for future generations.
