Water Rates Process

Water rates cover the cost of providing a reliable supply of high-quality drinking water to the communities of Fremont, Newark and Union City. The District regularly conducts an analysis to ensure water rates accurately reflect the cost of water service. 

On August 27, 2020, the District held a financial workshop to start a new rates process to review the allocation between fixed service charges and commodity charges in collecting revenues, the charges for dedicated fire service lines, and to provide an update on the District’s current financial status. View the presentation from the August 20 workshop.

On October 22, 2020, the District held a financial  workshop to continue the discussion regarding the District’s current and projected future financial status and potential water rates and charges increase. The workshop was conducted by webinar. Customers were invited to participate virtually to join the discussion and to learn more about the District’s finances, rates and charges, as well as the cost-of-service studies that the District is conducting to guide the rate setting process. View the agenda and presentation from the October 22 workshop. For additional in-depth information on the process, past financial workshops are available for review.

Following Board deliberation at workshops in August and October, District staff are preparing a water rates proposal with a 2 percent increase effective March 1, 2021 and another 2 percent increase effective March 1, 2022.  The Board will determine whether to proceed with this proposal or an alternative at its regularly scheduled Board meeting on December 10, 2020.  Information on how to participate in the virtual meeting will be available in the District's agenda center at least three days before the meeting.

There were a number of frequently asked questions by customers during the last rates process. View the rate increase FAQ document. 

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.

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. This covers a portion of the fixed costs of operating the water system, such as meter reading, customer service, service line and water main maintenance and renewal, and other infrastructure costs. 

Consumption Charge

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.

Determining Rates & Charges

As a public agency, ACWD cannot take in funds beyond the costs of providing its service. The District periodically conducts an analysis to ensure water rates accurately reflect the cost of water service. The District also uses outside expert consultants to ensure that its rates are properly determined. You can learn more about cost-of-service studies (PDF) and financial workshops that provide a deeper explanation of the process. Following a series of public workshops, the District notifies customers and the public about any proposed rate adjustments through various means:

  • A formal notice of any proposed rate adjustments will be mailed to all addresses within the District’s service boundaries. The formal notice contains the details of a public hearing where the revisions are proposed to be adopted by the Board after a formal 45 day public input period. View more information on District transparency.
  • Postings to the District’s website and social media sites
  • Email notifications to customers who have subscribed to receive board meeting notices
  • Press Releases
  • Printed advertisements in local newspapers.

The District continuously looks for and implements ways to minimize costs. These include delaying capital improvement projects when feasible, reducing staffing levels, and using the District’s diverse water supplies to maximize use of lowest-cost water. Cost controls have helped keep the District’s water rates consistently in the lower half of 30 Bay Area water agencies. You can view a chart that illustrates ACWD’s current average water bill in comparison to other Bay Area water agencies.

The District also continuously evaluates new revenue sources such as grant funds, and has secured about $18 million in grant funds and reimbursements in the past year, primarily for mandated fishery projects in Alameda Creek.

Cost Breakdown

To help customers understand how the District spends its funds, ACWD illustrates the FY 2020/20 budget in two ways: by major revenues and expenses.

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 $25 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.
