If your water bill is higher than normal, it may be time to check for a leak. Leaking water causes higher than normal water bills. What can you do?
Check the easy things first:
It might be out of sight:
Tuolumne Utilities District may provide a leak adjustment to metered water customers whose leak has caused a substantial increase in water consumption. If approved, a customer may receive a relief of 50% of the consumption portion of their bill, compared to the same billing period as the prior year. Leak adjustments may be granted every 3 years.
Leak Adjustment Guidelines:
All customers requesting a leak adjustment in accordance with the above guidelines are required to complete a Leak Adjustment Form. This form, along with the appropriate repair documentation, must be submitted for an adjustment to be considered. To obtain a copy of our leak adjustment policy and Leak Adjustment Request Form, please contact our Customer Service Department at (209) 532-5536 or by email at [email protected].
