How clean is raw stormwater? Understanding the hazards

Stormwater runoff is now commonly used as a valuable water source for  non-drinking purposes, and is beginning to be used for potable  reuse in some places.

Since raw stormwater is likely to contain chemical, microbial and toxicological  contaminants, understanding its quality is a key first step in planning a stormwater harvesting  scheme.

The attached Industry Note summarises research  by the CRC for Water Sensitive Cities, which has provided the first database of stormwater quality from a range of  catchments across Australia.
