Audit Objective: The objective of this fixed site audit is to ensure that Gippsland Water has procedures and systems in place to actively manage the systems associated with activities undertaken on site. When working on any Gippsland Water water treatment or quality sites, the Gippsland Water Drinking Water Quality Framework incorporating SDWA, SDWR, ADWG Regulations, Gippsland Water drinking water management systems policies, procedures, and all legal and other requirements (i.e. SOP's, legislation, regulation) must be adhered to. The audit team has the right to issue minor, major, critical non-compliance (NC); system improvements (SI); and/or observations (see Evaluation of Compliance Criteria for definitions) to the Responsible Officer (RO) of the site depending on the nature of the findings.

Compliance Evaluation Criteria Observation an issue that requires attention in order to improve the operation of the Drinking Water Quality Management System/Manual/Procedures and that if left un-addressed is likely to lead to a non-compliance during future self-assessment; or an example of good drinking water quality practice that deserves recognition; or flag or re-revisit at the next self-assessment. System Improvement an identified improvement in Gippsland Water’s Drinking Water Quality Management System/Manual/Procedures Non-compliance a non-fulfilment of a requirement, whether that of an Drinking Water Quality Management System/Manual/Procedures
