Preventing Pollution

By preventing pollutants from entering surface water and groundwater, our rivers, lakes, reservoirs and aquifers will continue to provide freshwater. Chemical and oil spills, and leachates from ground contamination are the major threats to freshwater. Bunding potential liquid pollutants, monitoring effluent, reducing discharges, using cleaner production techniques and ensuring proper waste disposal are some of the measures to prevent pollution.

PopUpFact

Choice of water

Grey water recycling consists of harvesting rainwater from the roof, filtering and storing it for later use and recycling water that has already been used.

Grey water suffers from images of filthy waste from washing machines. Yet, correctly treated grey water is as clean and clear as the water you would find in a swimming pool - something most people have no qualms about jumping into. This is more than adequate to flush the toilet.
