Bruma Lake receives its water inflow from a vast area.

The source of the Jukskei Spruit is from the underground waters from under the JHB CBD. Presently these waters are of good quality but will come under the rising threat of the raising Mine Waters in the area.

However because of development within the catchment area, most of the inflow is from the storm water drainage system. The storm water drainage system incorporating parts of Yeoville, Cyrildene, Observatory etc. to the North and parts of Jeppe and Jeppestown, Ellis Park, Judith Paarl, Kensington etc. to the South.

All pavement and street litter in these areas ultimately finds itself into Bruma Lake.

A huge influx of this accumulated litter happens every year at the start of the rainy season.

During the dry season, tons of litter and waste accumulates in the storm water drains In anticipation of this, an external company was engaged by the Council to remove it. They were on site within days of the first rains and have so far removed some 30 tons of inorganic litter that has been incinerated at their plant.
