Explanatory information:
OBJECTIVE
SA FO1
The Objective of this Part is to—
- safeguard people from illness, injury or loss (including loss of amenity) due to the failure of an on-site wastewater management system installation; and

- conserve water and energy; and
- safeguard the environment; and
- safeguard public and private infrastructure; and
- ensure that an on-site wastewater management system installation is designed and is capable of being maintained so that throughout its serviceable life it will continue to satisfy Objectives (a) to (e).
