About water meter

The water meter is an important "measurement meter" that serves as the basis for calculating water rates.
Since the amount of water used measured by the water meter is used for transactions or certification with customers, the standards are set by the "Measurement Law" to ensure proper weighing.
The validity period of the water meter is eight years after passing the test.
Water Works Bureau carries out systematic replacements before the expiration of the validity period.

Water Works Bureau will notify you in advance when the water meter installed at the customer's home has reached the replacement time due to the expiration of the validity period.
Notice of replacement of water meter is notified to customers using water supply by "news postcard" or "news leaflet".

※Some customers living in condominiums may also be notified by "news postcard" instead of "news leaflets".

Please note that replacement of the water meter will be replaced even if you are absent.
If you have any replacement for your absence or wish to change the schedule, please contact the contracted construction company listed on the postcard.

Replacement of the water meter will be performed by a contract contractor with Water Works Bureau. Contractors (workers) wear identification cards issued by Water Works Bureau and armbands of water meter replacement workers.

If an obstacle is placed around the water meter, meter reading or replacement is not possible.
Please do not place your car or luggage on the water meter.

After replacing the water meter, turbid water or water mixed with air may come out from the faucet.
Turbid water and air may cause equipment to malfunction, so after replacement, drain the turbid water sufficiently with a faucet before using the equipment.
In addition, in the water mixture faucet, please drain on the water side and drain.

If the water meter is replaced while the water supply pipe before and after the water meter is aging due to corrosion, etc., water leakage may occur.
In particular, if a water leak occurs in a pipe space such as an apartment, the lower floor may be flooded.
In order to avoid such accidents, we may stop replacing the water meter and ask customers to improve some of the water supply pipe, so we ask for your understanding and cooperation.
In addition, the cost of the construction of the water supply pipe will be borne by the customer.
