The challenge
A wastewater company does environmental work by definition. The challenge was not proving purpose but expressing it in indicators:
- Positive impact also needs measuring: treating water improves the environment, but it had to be quantified.
- Operational data, not reporting data: the information existed in process terms, not as public indicators.
- Diverse stakeholders: owner authorities, municipalities, staff and the public.
The auma solution
The report is built around what the organisation does and can evidence:
- Selection of environmental, social and governance indicators relevant to wastewater operations.
- Data collection and validation with the managers responsible for each area.
- A document written to be understood by non-technical audiences while keeping the figures rigorous.
The result
- Sustainability report delivered, with traceable indicators and documented methodology.
- The organisation holds a repeatable indicator framework for subsequent years.
- A transparency instrument towards owner authorities and the public it serves.
In a public environmental service, the sustainability report is not marketing: it is how you account for what is done with everyone's money and water.
Frequently asked questions
What is a sustainability report?
A document that periodically reports an organisation's environmental, social and governance performance, with quantified indicators and explicit methodology, addressed to its stakeholders.
Are companies required to publish one?
The obligation depends on the organisation's size and nature under European sustainability reporting rules. Many companies that are not required publish voluntarily, often because customers or owner authorities ask for it.
What indicators does a wastewater company report?
Volumes treated and effluent quality, energy consumption and energy recovered, sludge generation and destination, process-related emissions, plus the organisation's own social and governance indicators.
Do you need to explain your environmental performance with data?
We write sustainability reports with verifiable indicators and language people can follow.
