The City of Cape Town has urged residents to use boreholes and well-points responsibly and sparingly, as this is not an unlimited resource.
If too much groundwater is extracted too quickly it may become depleted.
For this reason, the City is recommending that customers with groundwater restrict watering to the hours prescribed and limit watering to the early mornings and/or late evenings to avoid evaporation.
The City though has indicated that it would be lobbying national government to more tightly regulate this resource for domestic use.
Residents have also been reminded that, once installed, boreholes need to be registered, and may have to be fitted with meters to monitor usage.
