An important factor influencing the location of Secunda was the availability of water. Water for the Sasol operations is supplied from the
Grootdraai Dam near
Standerton.
Streetscape The layout of the town is distinctive in that residential areas, or "quarter cells", are bordered by main roads and green strips. This design results in minimal through-traffic within residential zones. Pedestrian and cyclist access to schools, the central business district, and suburban shopping centres is facilitated by the green strips, which are free of vehicular traffic and provide shorter travel distances.
Architecture A defining feature of the landscape around Secunda is the presence of massive cooling towers, tall chimneys, and steel structures characteristic of South Africa’s oil-from-coal industry. The tallest structure in Secunda is the 301-metre-high chimney at the Sasol Synfuels plant. This
Eskom-type chimney comprising four refractory brick-lined concrete flues, each with a diameter of 4.6 metres. The outer windshield structure stands 292 metres high with an internal diameter of 26 metres. The chimney was constructed by

Hochtief, as part of the Sasol Synfuels steam plant project. Its foundation includes both vertical and raked
piles. It is considered one of the tallest free-standing structures in the
Southern Hemisphere.
