Case study for students: Meeting demand for drinking water.
| Water source | Surface water |
|---|---|
| Ability to manage supply to meet demand | Effective |
| Forecasting future demand | Forecasting is relatively detailed and likely to be accurate (for example, it includes analysis of factors influencing demand). |
| The existing supply is sufficient to meet projected demand. | |
| Planning to meet future demand | Planning and implementation are good. |
| Supply strategies include investing in new or upgraded infrastructure, looking for new water sources and a pressure-control programme. | |
| Demand strategies include universal water metering and charging, education and water restrictions when necessary. | |
| Quality of drinking water | Graded A in 2010. |
Water-quality grades: A = completely satisfactory, B = satisfactory, C = marginally satisfactory, D = unsatisfactory, E = unacceptable
