Sanitation treatment systems – ISO new work item proposal

We’re seeking feedback from relevant stakeholders on the International Organization for Standardization’s (ISO) proposal for a standard on ‘Community-scale resource-oriented sanitation treatment systems’.

All responses submitted to Standards New Zealand will help us to generate a New Zealand position on the proposal.

Please provide your feedback to by Friday 9 February 2018.

For more details, please consult the proposal [PDF, 663 KB].


The scope of the proposal is the following:

The international standard will define requirements and test methods to ensure safety, performance, and sustainability of community-scale resource-oriented fecal sludge treatment units that serve approximately 1,000 to 100,000 people. The standard will apply to treatment units that (a) primarily treat human excreta, (b) are able to operate in nonsewered and off-grid environments, and (c) are prefabricated. The standard will not apply to sanitation treatment units requiring sewer infrastructure or electric grid access. Additionally, treatment units to which the standard will apply exhibit resource recovery capability (e.g., energy, drinking water, fertiliser) and are capable of being energy independent or energy net positive.

The standard is intended to ensure the general performance, safety, and sustainability of such units. The standard will exclude installation, selection, and maintenance and operation of such units.
