Our water system at the school is dependent on the underground aquifer. We relie on three bore holes which are serviced by electrically powered pumps. Generally, we have no major water use restrictions. The excess use of water, e.g. watering lawns with hose pipes or sprinklers, is not allowed during the hot-dry season. We use no metres to monitor the use of water, though.
Water is used for agricultural irrigation, leisure, etc.
This is seconded by thermal. Solar power is a new phenomenon.
