The answer to this question depends on how long the leak lasts, whether the leak causes property damage, how much the repair costs, whether and how much of an account credit you receive after fixing the leak, etc. Below are estimates of water and sewer costs for leaks of various sizes, if they last for one day, week or month. As shown below, a small leak can be costly if it continues for a week or more.
THE INCREMENTAL COST OF A GALLON OF WATER AND SEWER SERVICE: 1.3¢
For an individually-metered residential customer using 4,000 to 5,000 gallons per month, the incremental cost of 1,000 gallons of water and sewer use is $6.39 per water (based on our block two water rate for 3,000 to 5,000 gallons of monthly water use) and $6.48 for sewer service, for a total of $12.87. This equals about 1.3 cents per gallon. For customers who use more than 5,000 gallons per month or less than 3,000 gallons per month, our water rates are higher or lower. Please click here for an explanation of OWASA's monthly bill for individually-metered residential customers for more information on our increasing block water conservation rates, which rise with the level of monthly water use.
GALLON AND DOLLAR COSTS OF RESIDENTIAL LEAKS
For non-residential customers, who pay seasonal water rates, the cost of a leak depends on the time of year and whether the higher “peak” seasonal rate or the lower “off-peak” seasonal rate is in effect. Sewer charges per 1,000 gallons do not vary with the season, but they may change in October with annual rate adjustments.
