Domestic Waste Water Cycle

Human use of water affects the water cycle in a variety of ways.

Specifically, water is drawn from its ordinary course of function within the water cycle and applied to domestic, agricultural and industrial uses. This diverted water, once used, must be returned to the water cycle somewhere further downstream.

Diverted wastewater falls into two categories depending on the degree of human waste it contains. Greywater is the most significant proportion of wastewater and flows from non-effluent sources such as drains, sinks, baths and showers. Blackwater is from your toilet.

All water used in a domestic situation must be collected and treated by statutory requirements before returning to the water cycle. A fully approved on-site wastewater treatment system must be used in houses not connected to a centralised sewage system.

Garden Master Septic Systems treat both black and grey water and, after processing it, returning it to the environment through a suitable irrigation system to the designated land application area.
