Extract out of the presentation:
Rainwater management
. Bloemfontein has a surface area of approximately 120 km2 and an average annual rainfall of approximately 550 mm.
. Total rainfall per annum: 66 million m3.
. This volume exceeds the current municipal water demand, even after accounting for evaporation losses and groundwater recharge.
. Most of this water is lost through the storm water drains, eventually ending up in the Modder River.



Groete/Greeting
Ludwig, Retha & Arno Everson
