Q; How can I find water leaks?

A; You can find leaks simply by looking at your home's water meter.
If the pilot in the water meter is turning round even when you are not using any water, then there may be a leak somewhere between your water meter and the taps.

Q; There is a leak on my property. What should I do?

A; If it is clear that the leak is occurring on the house side of the water meter, you should request a repair from a Tokyo designated plumbing contractor (a plumbing firm that has been designated by the Tokyo Metropolitan Government) or from the Maintenance Center (Telephone Number: 3585-0195).

Q; There is a water leak on the road. What should I do?

A; If it occurs in the 23 wards of Tokyo, the staff of the Bureau of Waterworks, or if it occurs in the Tama District, the staff of Tokyo Water Co., Ltd. who are subcontractors of the Bureau of Waterworks, will conduct an inspection. So please contact the Bureau of Waterworks Customer Service Center, or the Bureau of Waterworks Tama Customer Service Center.

Q; I had the water leak fixed, but is it possible to have my water charges reduced by the amount of the leakage?

A; The water supply infrastructure in your home is the property of the customer and it is your responsibility to manage it. Even if a leak occurs, you will have to pay for the amount of water recorded by the meter.
However, depending on the circumstances, there may be some cases where your bill could be reduced. For details please contact the service station responsible for your contract.

Q; How much will a leak affect the size of my bill?

A; This depends on the size of the leak. Even if the leak is initially small, with each day that passes more water will leak out, and not only will valuable water be lost, your charges will also mount up to a large amount.

Q; How much does it cost to repair a leak?

A; This depends on the condition of the leak. We recommend getting a Tokyo designated plumbing contractor (a plumbing company that has been designated by the Metropolitan government – if possible, multiple companies) to submit an estimate. The preparation of an estimate may also involve a cost, so check that in advance with the contractor.

Q; I requested the maintenance center to repair a leak but was told they can’t do that. Can I get the Bureau of Waterworks to do it?

② Cases in which leaks cannot be repaired because of technical or material shortages
　Repair of leaks in water supply equipment sometimes requires specialized material or techniques, and sometimes the plumbing contractor initially contacted may be unable to carry out the necessary repairs.
We apologize for any inconvenience, but in that case, please contact the maintenance center again to explain the situation and allow them to introduce you to other plumbing contractors.

Q; The maintenance center introduced me to a plumbing contractor who can repair my leak, but their charges are too high. I’d like you to instruct them to lower the charges.

A; The contents and cost of repairs are a contractual matter between the customer and the contractor. The Bureau of Waterworks cannot issue instructions in relation to the price of repairs.

Q; I hear that only a plumbing contractor designated by the Bureau of Waterworks can carry out water service installation work. Why is that?

A;　If inappropriate materials and construction techniques are used to repair water supply equipment, customers cannot enjoy safe and high quality tap water, and moreover, concerns also arise about public health problems.
For those reasons, the Bureau of Waterworks designates plumbing contractors who are accredited as capable of carrying out the appropriate work to install or modify water supply equipment.
The standards for designation are determined by the Water Supply Act and are the same nationwide. So, in the case for a request for designation, when the Bureau of Waterworks accepts that a plumbing contractor meets the criteria, we must confer the designation.

 

Q; I am not using any water at all, but the pilot on my water meter is still turning. What should I do?

A; It is possible that you have a leak.

①If you already know a plumbing contractor.
You should contact the plumbing contractor yourself and ask for advice.

②If you do not already know a plumbing contractor.
