[DWA01] Registrations of Domestic Waste Water Treatment Systems
Updated by provider on September 26, 2025 (11:00 AM).
The Domestic Waste Water Treatment Systems 2023 and 2024 releases show revisions when compared with corresponding figures in previous releases due to a change in methodology. In previous releases, registrations in early months of the year following the reference year were included and classified as existing registrations. From the 2023 release onwards, the methodology has been revised to exclude these registrations. As a result, there was a small decrease in annual total registrations and existing registrations for pre-2023 figures compared with previous releases. See Background Notes of statistical release
