Tianjin Water Group has swapped in remote-read meters for 3 million-plus households since 2019. The city's own water authority says network leakage is now down to 9.4% — a self-reported number, with no independent audit found.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

Since 2019, Tianjin Water Group has been replacing residential analogue meters with remote-read NB-IoT smart meters that report consumption automatically and enable app-based (Alipay/WeChat) bill payment. By an October 2022 municipal water-conservation conference, more than 3 million meters had been replaced and over 600 km of aged (50-plus-year) supply pipe renovated, and Tianjin's Municipal Water Authority reported the city's public water-supply network leakage rate had fallen to 9.4%. The replacement programme, run through Tianjin Water Group's district service centres, was still actively processing resident applications as of April 2025.
📊 Impact
Tianjin's public water-supply network leakage rate had fallen to 9.4% as of an October 2022 municipal conference, after Tianjin Water Group replaced more than 3 million meters and renovated over 600 km of aged pipe since 2019. Self-reported by the Tianjin Municipal Water Authority; no independent audit was found.
🎓 Lesson
The leakage rate and the meters arrived together with something else. In the same period Tianjin Water Group renovated more than 600 km of supply pipe over fifty years old, so the 9.4% figure covers a network that was being physically rebuilt while it was being metered — nothing in the record separates the two. The figure is also the water authority's own, announced at its own water-conservation conference, and no independent audit was found. What the meters demonstrably changed is the billing relationship: readings arrive without a visit and residents pay through Alipay or WeChat.

Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
