Water Wise Watch - January 2021
04.01.21
As the new year begins and we embark on a new chapter of our lives, may we look forward to making new memories. May 2021 restore all that has been lost. May we hold onto our HOPE, but most importantly, may we keep each other safe.
Happy New Year to ALL from Water Wise.
- Hydrozoning of plants: this is the grouping of plants according to their watering needs. Hydrozoning prevents the unnecessary watering of plants. Plants are grouped according to high, moderate, low and no water use categories.
- Rainwater harvesting: using rain water tank systems, rain water is captured from the roof of the lapa and directed straight to a storage pond.
- Permeable hard landscape that allows water to percolate into the soil.
- A seating area that allows visitors to explore the surrounding landscape.
- A play area for children with artificial lawn covering the ground, making it a low maintenance and no water use area.

Control erosion by utilising smart plants
Soil erosion is very devastating in landscapes that are situated on slopes. Important nutrients in the soil may run off after heavy rainfall events or irrigation, preventing plants from absorbing the necessary minerals to sustain growth. As a result, plants end up dying and this then creates patches within the landscape. One way of mitigating the effects of erosion by water is by using suitable plants that are wind resistant, able to spread along the ground, low maintenance and can be used as a living mulch to help preserve water in the soil. An example of suitable ground covers are Plectranthus ciliates, Dymondia margaretae, Carpobrotus deliciosus and Aptenia cordifolia (see below images).

Reduce water flow
Putting a bathroom renovation off is one thing, but putting the replacement of your plumbing accessories off is another. You can save water in your bathroom by simply inserting flow regulators in the taps and shower heads. Flow regulators can be inserted in old and modern taps and showers to help reduce water usage by 50% without negatively impacting the water flow, but reducing the flow rate.
There are two new DIY videos on our YouTube channel. These show you how to make your own rain gauges and watering cans from household items. Click on the YouTube icon below to go to our channel.
