Understanding Your SAWS Water Bill Basics
SAWS stands for San Antonio Water System, which provides water and wastewater services to the San Antonio, Texas area and surrounding communities. Your monthly SAWS water bill is the statement you receive that shows how much water you used and how much you owe for that usage, plus any additional charges or fees. Understanding what appears on your bill is the first step toward managing your water account responsibly.

Your SAWS bill typically arrives once per month and contains several key pieces of information. The bill shows your account number, the billing period covered, your current meter reading, and the amount of water you consumed measured in units called hundred cubic feet (HCF), also written as CCF. One HCF equals 748 gallons of water. The bill also displays your service address, any previous balance owed, and the total amount due by the payment deadline.
SAWS bills include charges for both water consumption and wastewater treatment. The water charge covers the cost of treating and delivering fresh water to your home. The wastewater charge covers the cost of collecting and treating the water that leaves your home through drains and toilets. If you have a sprinkler system, you may also see separate charges for outdoor water use. These different charges allow SAWS to track water usage patterns and help customers understand where their water costs come from.
The billing structure in San Antonio uses tiered pricing, which means the rate per unit changes depending on how much water you use. During winter months, tier 1 rates apply to the first amount of water used, with higher rates kicking in if you exceed that amount. During summer months, the tiered structure may shift to encourage water conservation during hotter, drier periods. Understanding these tiers helps explain why your bill may vary from month to month even if you use water at similar levels.
Practical Takeaway: Before you pay your next bill, locate each section of your SAWS statement and identify the current charges, your meter reading, and the due date. Keeping this information organized in a folder or digital file will help you track changes in your usage over time and catch any unusual charges.
How to Calculate Your Water Usage and Charges
Reading your SAWS water meter allows you to verify your usage between billing periods. Your meter measures water consumption in hundred cubic feet. To find your current usage, look at your meter reading on the current bill and subtract the previous month's reading. The difference is how much water you consumed that month. For example, if this month's reading is 1,250 HCF and last month's reading was 1,220 HCF, you used 30 HCF that month, which equals approximately 22,440 gallons.

SAWS charges customers based on consumption levels that vary by season. In 2024, the winter rate structure (November through March) typically includes tier 1 rates for the first 6 HCF per month, with higher tier 2 rates applying to usage above that amount. Summer rate structure (April through October) may apply higher rates to encourage conservation. For instance, if winter tier 1 rates are around $3.50 per HCF and tier 2 rates are around $5.75 per HCF, a household using 8 HCF would pay approximately $3.50 × 6 = $21 for the first 6 units, plus $5.75 × 2 = $11.50 for the additional 2 units, totaling about $32.50 before wastewater charges.
Your wastewater charge is calculated based on your water consumption, as SAWS assumes that most water entering your home eventually leaves as wastewater. The wastewater rate per HCF is typically lower than the water rate but still represents a significant portion of your bill. Some SAWS customers have separate meters for irrigation water, which is charged at a different rate and does not generate a wastewater charge, since outdoor water does not enter the sewer system.
SAWS bills may also include fixed charges that appear on every bill regardless of usage. These charges cover meter maintenance, billing services, and system infrastructure. Additionally, customers may see line items for stormwater utility fees in some service areas, taxes, and other municipal charges. Some customers qualify for reduced rates through specific programs, though these are evaluated on a case-by-case basis and require verification of eligibility through SAWS directly.
Practical Takeaway: Review your last three monthly bills and calculate your average monthly usage. Compare this to your current bill to spot any sudden increases that might indicate a leak or unusual consumption pattern. A significant jump in usage often occurs when outdoor irrigation starts in spring or when a household member changes their water habits.
Payment Methods and Options Available to SAWS Customers
SAWS offers multiple ways to pay your water bill, allowing you to choose the method that works best for your situation. The most common payment method is online payment through the SAWS website at saws.org. To pay online, you'll need your account number and either a checking account, savings account, or credit/debit card. Online payment typically processes within one to two business days and allows you to schedule payments in advance or set up automatic recurring payments.

Automatic payment is another popular option that removes the need to remember your due date each month. You can arrange automatic payments through your bank's bill payment service or directly through SAWS. When you set up automatic payments, your bill amount is withdrawn on a date you specify each month. Many customers choose to have their payment processed a few days before the due date to ensure on-time payment. Some banks may charge a fee for bill payment services, so check with your financial institution about any costs associated with this option.
Phone payment is available by calling SAWS customer service at 210-704-7275. A representative can process your payment over the phone using a credit card, debit card, or checking account information. Phone payments are useful if you prefer speaking with a person or need to ask questions about your bill at the same time you pay. Payment by phone typically processes within one business day. Some customers use this method to resolve billing issues before making their payment.
Mail payment and in-person payment at SAWS payment locations remain options for customers who prefer not to use electronic methods. If you pay by mail, send your check or money order with your payment stub to the address listed on your bill. Payment by mail typically takes five to seven business days to process, so mail your payment early if your due date is approaching. SAWS also accepts in-person payments at several service locations and authorized payment centers throughout the San Antonio area during business hours.
Practical Takeaway: Choose one payment method and use it consistently. If you select automatic payment, verify that your account information is correct before the first payment processes. Set a calendar reminder to review your bill each month even if you have automatic payments, so you can catch any billing errors or unusual charges promptly.
Due Dates, Late Fees, and Payment Deadlines
Your SAWS water bill includes a due date, which is the deadline by which you must pay to avoid late fees. The due date typically falls 20 to 25 days after the bill is issued. The specific date depends on when your meter is read and when SAWS processes your billing. Late fees are assessed when payment is not received by the due date shown on your bill. Currently, SAWS charges a late fee on accounts that become delinquent, meaning the fee is added to your balance if you do not pay by the deadline.

Understanding the consequences of late payment helps you prioritize paying your water bill on time. If your payment arrives after the due date, you may owe a late fee in addition to your regular bill amount. The exact fee amount appears in SAWS' rate schedule, which is available on their website. Additionally, if your account becomes significantly delinquent—typically after 30 to 45 days of non-payment—SAWS may issue a notice of intent to disconnect service. This notice informs you that your water service could be shut off if you do not bring your account current.
If you cannot pay your full bill by the due date, contact SAWS before the deadline to discuss your options. SAWS customer service representatives can explain what arrangements may be available in your situation. Some customers work out payment plans where they pay a portion of the bill by the due date and the remainder over subsequent billing cycles. Making contact before your account becomes delinquent shows good faith and often results in more favorable arrangements than waiting until after the disconnection notice arrives.
