About Your Water/Wastewater Bill                               

Every two months the City of Thousand Oaks reads your water meter to find out how much water has been used during the period. (Commercial customers meters may be read each month.) The service charge is a minimum, bimonthly charge determined by the service size, plus the cost of water actually used. The City is one of four local water purveyors. Wastewater-only is billed a flat-rate amount every two months.

Reading Your Meter

Reading your water meter will tell you how much water you're using and whether you have a leak. Most meters are located near the curb in front of your home or business, under a concrete lid.

Billing units are in hundred cubic feet "HCF"; to obtain HCF, read all digits except the last two. Subtract your last reading from the current reading to determine your use in hundred cubic feet. To convert your usage to gallons, multiply by 750 (one hundred cubic feet (1 HCF) equals 748 gallons). To check for leaks, turn off all water inside and outside your residence -- if the flow indicator (colored plastic triangle on the face of the meter) moves or rotates, then you have a water leak.

Always replace the concrete cover, even if you'll "only be gone a minute."
