Domestic Waste Water Cycle

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

Specifically water is drawn from its normal 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.

Wastewater can be divided into two categories depending on the degree of human waste it contains. Grey water is the largest proportion of wastewater and flows from all the non-effluent sources such as drains, sinks, baths and showers. Black water is from your toilet.

By statutory requirement all water used in a domestic situation is required to be collected and treated before it is returned to the water cycle. With houses that are not connected to a centralised sewage system this treatment must be carried out in a fully approved on-site wastewater treatment system.

Garden Master Septic Systems are designed to 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.
