WATER USE AND TOTAL WATER USAGE PROJECTIONS The Otay Water District bills customers approximately every 30 days; a billing cycle may vary between 29 to 31 days depending on the actual day the meter is read. Customers are billed for the exact number of days between billing periods. Water consumption is measured and billed in units of 100 cubic feet or HCF; one HCF is 748.5 gallons of water. YOUR TOTAL WATER USAGE is the difference between the current meter reading (TODAY S METER READING) and the previous meter reading (LAST METER READING). To figure out your average daily usage, YOUR TOTAL WATER USAGE is divided by the number of days between the meter readings. It is easier to understand this number when calculated in gallons per day. The NEXT BILL PROJECTION is the average daily usage in GALLON PER DAY multiplied by 30 DAYS. The Otay Water District will display total water usage in HCF on your water bill. If a bill projection indicates a significant increase in water usage, this may be due to various factors: seasonal changes with resultant increase in exterior water usage; planting a new lawn or plants with additional water usage; or, a property-side leak which may need immediate attention. The most common property-side leak is a toilet leak which may vary from between 20 gallons per day to more than 4,000 gallons per day. Make Every Drop Count!
