Leaks are a common cause of higher consumption than normal and higher than expected water bills. They can be along the service line from the meter to the residence or in the house. Your water meter may be your most useful tool in identifying water leaks on your property. Below are some directions on how to use your meter to check for a leak.
Costs related to locating and repairing are yours to bear irrespective of the outcome. King County Water District 90 is not responsible for leaks after the water meter. Service line and all interior fixtures are property of the homeowner. Therefore costs incurred for leak detection, contractor and/or plumbing charges are the homeowner’s responsibility.
If you have a leak in your main service line (the water line that runs from the meter to your house), you may qualify for a leak adjustment once the line has been repaired or replaced.
The District's responsibility, as far as the water distribution system is concerned, ends at the water meter. The customer owns the service line from the meter to the residence. Repair of leaks along the service line or in the house are the customer's responsibility.
The District makes every effort to notify customers that a leak may be present. District Staff is "flagged" by the "Conintuous Flow Report", provided by Neptune 360, which notifies the District staff that there may be a leak at the customer's location.
Notification of a potential leak by the District is considered a courtesy, and not a requirement. Ultimately, it is the responsibility of the homeowner to determine if their higher usage is due to a leak.
Since our community's water supply is limited and using it efficiently is of prime importance, we urge customers to repair all leaks promptly. To support our customers in this endeavor, the District offers a one-time leak adjustment (Review No. 6). Leak adjustments are applied to one billing period (two months).
However, if the same leak extends into a second billing period, a second leak adjustment can be considered. In no instance will a leak period longer than two billing periods (four months) be considered for adjustment.
To qualify for the leak adjustment, leaks must be repaired within 30 days from the District’s leak notification or 30 days from the time the customer detects the leak.
Leak adjustments are for leaks in the service line (from the meter to the house).
Leak adjustments are also available for irrigation/sprinkler systems, running toilets, faucets, water heaters, hoses, or other above-ground or in the home systems and will be considered on a case by case basis.
The owner is eligible for a one-time leak adjustment during the life of the user’s service line. A new owner is eligible for a one-time leak adjustment on the same service line even if the previous owner received one.
If a second leak is discovered and the owner replaces the total service line (meter to the house) a second adjustment can be considered once documentation and inspection by the District verifies the replacement. There is a $50 charge for the inspection.
Please note, consideration to approve additional leak adjustments is on a case-by-case basis and is at the sole discretion of the General Manager. The District will always send out a field tech to verify the leak has been repaired before issuing any leak adjustment and there will be a $50 charge for this inspection.
To be eligible for the leak adjustment, a customer's usage must be at least $50 above an average bill.
To initiate the process, the customer must complete the District's Leak Adjustment Request Form. A downloadable version is available the application from our Website in the Document Library > Applications section. Copies of receipt(s) from the plumber or contractor's work and materials used in the repair must be submitted along with the Leak Adjustment Request form.
Once the District office has received the request form, our field staff will verify that work has been completed and is no longer leaking. There is a $50 charge for this inspection.
The leak adjustment is calculated by collecting the previous three-year consumption history (or the number of years of history available up to three years). This billing history is used to calculate an "average water usage" for the same billing period during the previous years.
The average water usage figure is then deducted from the leak water bill usage. Next, the cost of additional water purchased from Seattle Public Utilities is determined. Credit is calculated that is equal to the amount billed, less both the customer’s average consumption and the cost of additional water purchased by the District. The leak adjustment is then applied to the customer’s current bill, and a copy of the adjustment is sent to the customer.
The first step is to find a plumber or contractor that can help you identify and fix the leak or plan to fix the leak yourself. The District encourages customers to call more than one contractor to get competitive quotes. The District does have an email on how to use your meter to detect leaks and a list of contractors who help with leak detection/repairs that can be sent to you upon request.
