Understanding Your Water Bill
ACWD bills customers every other month, or six times per year. On these bimonthly bills, a customer is billed both a fixed "service charge" and a "consumption charge" based on the quantity of water used during the billing period. To learn more about how the District sets water rates and charges, please visit the Water Rates Process page. You may also view the full Schedule of Rates and Fees.
Bimonthly Meter Service Charge
Water customers are charged a fixed service charge based on the size of each meter at the customer’s property. For residential customers – who typically have a meter accommodating either 5/8- or 3/4-inch pipe -- the current service charge is $56.61 bi-monthly. The charge is designed to recover costs which do not vary with consumption. These costs include meter reading and billing customers for each bimonthly period, a portion of the District's debt service costs, and maintenance and replacement of meters and service lines in the distribution system. The charge is in addition to the District's commodity charge which is based on the amount of water consumed.
|Meter Size||Current Charge|
|5/8" & 3/4"||$ 56.61|
|1" Meter||$ 87.29|
|1-1/2" Meter||$ 163.97|
|2" Meter||$ 255.99|
|3" Meter||$ 547.39|
|4" Meter||$ 976.81|
|6" Meter||$ 2,464.48|
|8" Meter||$ 4,304.88|
|10" Meter||$ 6,451.99|
The water consumption charge is based on the number of "units" used by each customer. One unit is equivalent to 100 cubic feet or 748 gallons of water. The water consumption charge is currently $4.596 per unit for the typical customer.
The average single-family residential customer currently uses about 16 units of water in a two-month billing cycle, or about 200 gallons per day. This means an average bi-monthly bill of $130.15.
Commodity Rates (All Customers):
|Type||Base Rate Per 100 Cubic Feet (100 Cubic Feet Equals 748 Gallons)|
Bi-monthly Private Fire Service Charge
Private fire services are charged a bimonthly service charge based on the size of the detector check. There is also a bimonthly service charge for the bypass meter installed with the detector check, based on the District's established service charge for standard type meters.
|Detector Check Size (Inch)||Amount|
|4 or less||$ 14.40|
Customer Assistance Program - Help on Tap
ACWD recognizes some customers may experience difficulty paying their water bills. The District’s customer assistance program, Help on Tap, provides income-qualified residential customers a $35 credit on the bimonthly water service charge.
The Board approved an update to the program income guidelines effective in March 2020, setting the household income limit at the greater of 50% of Area Median Income or 250% of the Federal Poverty Level. More information and applications for Help on Tap are available on the District’s website.
