A practical backup water source

For homeowners in suitable areas of Hermanus, a well point can be a highly useful additional water resource.

Depending on the water quality, it can potentially be used for garden irrigation, topping up swimming pools, or, where appropriate and subject to suitable water-quality testing and treatment, for use within the home.

A key advantage of a well point is its ability to provide independence from the municipal water supply. It can be particularly useful as a backup source during periods when municipal water is restricted or when homeowners want to reduce the cost of watering their gardens.

Well points in the Hermanus area are generally installed at relatively shallow depths, often between approximately three and nine metres. Local ground conditions and the availability of shallow groundwater largely determine the depth.

Hermanus benefits from significant water seepage from the surrounding mountains. This contributes to the movement and replenishment of water below the surface and helps make well points a viable option in certain areas.

Groundwater availability, however, varies considerably from property to property. Some areas have a particularly high success rate with well points, while other properties may produce less water or may not be suitable at all.

Local ground conditions and experience are therefore important considerations when assessing a property.

UNDERSTANDING WELL POINT WATER SUPPLY:

A well point should not necessarily be viewed as a limitless water source. Like any shallow groundwater system, its yield can vary.

Generally, a well point may produce less water during summer than during winter. In some properties, the available flow can also decrease after sustained daily use.

If, however, the well point is given sufficient time to recover – sometimes just a few hours – water can become available again at different intervals throughout the day. This makes correct management particularly important.

It is recommended to use a well point as a backup rather than an alternative water source, avoiding the impression that a well point will necessarily replace municipal water altogether.
