- Domestic rainwater harvesting system
A domestic rainwater harvesting system can consist of a
collection surface, a storage tank, and guttering or channels to
transport the water from one to the other. Other peripheral
equipment is sometimes incorporated, such as a first-flush
system to divert the initial dirty water that contains roof debris
built up during prolonged dry periods; filtration equipment; and
settling chambers to remove debris and contaminants before
the water enters the storage tank or cistern. For detail section
of this see figure 11.15.
