RAND WATER FEATURE

GOING BEYOND

IRRIGATION:

NATURAL POOLS

AND SUSTAINABLE

WATER DESIGN

ut the water­wise revolution doesn’t stop at the
garden bed. Innovative design choices are helping
Bto transform the way we think about water in the
landscape, and one of the most exciting trends is the rise
of natural swimming pools. Unlike traditional pools that
rely on chemicals and consume vast quantities of potable
water, natural pools are eco­friendly, self­sustaining systems
that bring both form and function to a garden.
In the Highveld, a standard pool can lose between 2 and 3.5
metres of water per year through evaporation alone. This is a
massive loss, particularly in a region already facing water stress.
Natural pools offer a compelling alternative as they mimic the
structure of wetlands or river ecosystems, using indigenous aquatic
plants, gravel, bark and beneficial micro­organisms to purify the water
naturally. Instead of chlorine, plants and microbes keep the water clean
and clear, creating a safe and chemical­free swimming experience.
A typical natural pool includes a top wetland zone, essentially a raised,
planted filter bed, and a lower wetland or regeneration area filled with water
lilies and aquatic vegetation. As water circulates through these zones, it
undergoes filtration and oxygenation before flowing back into the
swimming area. Maintenance is minimal: monthly clearing of debris
and light pruning of aquatic plants is usually sufficient to keep the
system thriving.
Beyond their aesthetic and ecological appeal, natural
pools also support biodiversity by creating habitats for
aquatic birds and animals. Even better, these pools
offer extended water storage that can be tapped for
garden irrigation, particularly during dry periods. By
integrating rainwater harvesting and solar­powered
pumps, these systems can even function completely
off the municipal water and energy grid ­ a bold step
toward self­sufficiency.
For landscapers, incorporating natural pools
and adaptive irrigation systems offers clients
a tangible solution to rising water costs, while
aligning with growing environmental awareness.
For homeowners, it means enjoying a lush,
sustainable garden and the luxury of a private,
chemical­free swimming haven, all while doing
their part to protect Gauteng’s precious water
supply.
As we face mounting climate pressures and
shifting weather patterns, the role of the landscape
professional becomes more vital than ever. With
thoughtful design, smart technology and a few key
changes in how we water, we can create gardens that
are not just beautiful, but resilient for the future. n
