Residential Water

Customers pay a monthly base fee plus the tiered rate per 1000 gallons of water used. The base fee is determined by the meter size and the tiered rate is based on the monthly volume.

Tiered Water Rates

The City of Round Rock employs rates designed to encourage water conservation throughout the year by charging a higher rate to higher usage customers. Customers who use 15,000 gallons a month or less – 74 percent of residential users – will not see any change in their monthly bills. Those using more than 15,000 gallons a month comprise about 20 percent of our residential customers, but that 20 percent consume approximately 50 percent of all water used by residential customers.

By watering wisely and installing drought-tolerant landscaping, higher rate users can reduce their consumption and pay the lower rate. See Water Conservation for more water-saving tips.

The table below indicates the volume (gallons) for each tier based on meter size. The standard residential meter is 5/8 inch.

Wastewater Averagingrr-indr-wtr-grphc-trans

Each year, the City takes your average water use for the months of November, December and January to calculate your wastewater usage for the year. Typically, water use is the lowest this time of year due to little or no outdoor water use.

Depending on your route, consumption used to calculate your wastewater average may come from usage in November, December, January, and February. Watch your bills to determine the approximate date on which your meter is read each month. Your wastewater average calculation will start on the day your meter is read in November and will end on the day your meter is read in February.

Connection Fee and Deposit

The connection fee and deposit will be reflected on your first month’s bill. A service connection fee of $25 is required for each new connection or transfer of existing service. If a customer requests service after normal business hours or same-day service, they are responsible for the $25 connection fee plus the $75 after hours/same day fee.

Deposits are based on meter size. The standard residential meter size is 5/8 inch.
  • 5/8 inch to 1-inch meter – $100
  • 1 1/2 inch meter – $150
  • 2 inch and larger – $100 per inch or fraction thereof
The deposit will be refunded to the customer when:
  • Service is canceled; provided, however, that any unpaid charges will first be deducted from the deposit; or
  • The customer has 12 consecutive months of satisfactory payment history.

If the city has refunded the customer’s deposit for “satisfactory payment history,” and thereafter the customer’s service has been discontinued for non-payment or meter tampering, then the customer will be required to pay the deposit again.

Late Fees

Utility customers have 16 days from the date the bill is mailed to pay the balance due on their account without penalty. The payment due date is noted on each bill you receive. Any due date falling on a weekend or holiday will be extended to the following business day. Payments made after the payment due date are subject to a late fee. Late fees are assessed on the day after the due date and are 10 percent of the past due balance or $2.50, whichever is greater. For payment options go to Make a Payment.

Residential customers over 60 years of age can apply in writing to waive late fees up to 25 days beyond the original due date.

Service Interruptions

Service may be disconnected if payment has not been received within 14 days of the bill due date. To have service restored on the next business day, the customer must pay the past due balance plus the $50 service fee during normal business hours. To have service restored on the same day, the past due balance plus the $75 service fee must be paid by 4:30 p.m. To have your service restored please contact the Utility Billing office.

Additional Trip Fees

The City charges $25 for additional trips to re-read meters unless the trip is caused by the City’s error. If plants, large rocks, building structures or any other obstacle hinders or prevents the meter from being read, the obstacle will need to be removed and an additional trip fee will be charged for having to re-read the meter.

Admin Fee

As an incentive for on-time payments, the City has adopted a $25 fee for utility customers who don’t pay by the disconnect date. The $25 fee is applicable even if service isn’t disconnected.
