The rollout so far is 81 meters at 63 sites. Mobile networks are judged too unreliable for the rest, so the bureau is testing whether water readings can ride the electricity smart-meter network.

Osaka's municipal waterworks bureau tested radio-linked water meters over LoRaWAN from 2015 to 2017, then in April 2019 fitted 81 meters at 63 sites in the Nanko Sakishima waterfront area so they could be read remotely instead of on foot. A separate trial from December 2018 to March 2022 put narrowband meters in 30 mostly single-elderly households and watched consumption patterns for signs that something was wrong. Citywide reading remains distant: the bureau says mobile networks are not reliable enough, and since February 2024 it has been researching with the regional electricity distributor whether water readings can ride on the electricity smart-meter network instead. A strategy adopted in August 2025 targets deployment across the whole service area only in the 2030s.
