Reduce Unexpected High Water Bills After a Leak — Step-by-Step Guide
Introduction
A sudden spike in your water bill can be shocking — especially when caused by a hidden or underground leak. Fortunately, several utilities in King County offer leak adjustments (sometimes called leak bill forgiveness) to help homeowners reduce the financial burden when a verified leak causes excessive water use. This post walks you through how leak adjustments work in King County and exactly what you need to do to apply.
What Is a Leak Adjustment?
A leak adjustment is a billing credit applied to your utility bill when a verified leak (especially underground or service line leaks) leads to abnormally high water usage.
• It doesn’t refund the cost of repairs.
• It recalculates excess water charges based on your normal usage history. (King County Water District #90)
Who Offers Leak Adjustments in King County?
Different municipalities and districts in King County have their own policies — here are a few key examples:
1. Seattle Public Utilities (SPU)
- Offers leak adjustments on water and sewer charges for most leaks.
- Underground leaks between meter and foundation require inspection before repairs are covered.
- You must provide proof of repair or inspection completion. (Seattle)
2. King County Water District No. 90 (Renton area)
- Provides a one-time leak adjustment applied to the billing period where the leak occurred.

Step-by-Step: How to Successfully Apply for a Leak Adjustment
Here’s your roadmap to increasing your chances of approval:
1. Identify the Leak Quickly
Before anything else — find and fix the leak. Use your monthly bill history and sudden water usage surge as a clue. Specialized leak detection pros can help locate underground/service line leaks.
2. Fix the Leak Promptly
Most utilities require repairs within a specific time window (e.g., 30 days). Save all receipts, invoices, and documentation from your plumber or contractor.
3. Gather Required Documentation
Typical requirements include:
- Leak Adjustment Request form (from your city/district).
- Proof of repair — paid invoices, receipts, photos, or inspection confirmation.
- Your recent water bills for comparison.
Seattle, for instance, may require an inspection for underground leaks before repairs are covered. (Seattle)
4. Submit Your Leak Adjustment Request
Depending on your utility:
- Online portals (e.g., Redmond)
- Mail or in-person
- Call customer service first to clarify next steps
Be sure to submit before your next billing cycle when possible.
5. Follow Up
If your adjustment is denied or you don’t hear back:
- Call your utility’s billing support number.
- Ask for specific reasons and what additional documentation is needed.
How Leak Adjustments Are Calculated
Utilities typically calculate a leak credit by:
- Reviewing past water usage over prior years.
- Calculating average water consumption for the same billing period.
- Subtracting that average from the bill with the leak.
- Applying a credit based on the utility’s policy rules. (King County Water District #90)
What Leaks Usually Do Not Qualify
Most utilities don’t cover:
- Above-ground leaks (e.g., irrigation systems)
- Running toilets or faucets
- Leaks caused by negligence or delayed repairs
Seattle’s policy explicitly excludes aboveground or indoor fixture leaks from adjustment eligibility. (Seattle)
Tips to Improve Your Adjustment Approval Chances
✅ Fix leaks as soon as possible after discovery
✅ Submit complete documentation at once
✅ Contact utility billing before repairs if possible
✅ Keep good records of meter reads and communication
