Do I still pay surface water drainage charges if I have a rainwater harvesting system?

If the rainwater harvesting system recycles the majority of the surface water to be used for garden irrigation, and very little rainwater is returned to the public sewer, an allowance is due.

However, no allowance is due if the water is recycled for domestic purposes, e.g., toilet flushing.
