City seeks water customers who earned conservation discounts

The Water Utilities Department is seeking to refund $284,138 to 25,031 water customers who did not receive conservation discounts they have earned since 2009.

The average credit owed is $11.35 per customer. In total, 14,225 customers with active accounts are owed $197,557. Another 10,806 non-active account holders are owed $86,581. Active customers will be credited the amount they are due during their next monthly billing cycle. The names of former water customers who earned discounts are published here, along with information about how they can claim their credits.

Water customers earned a conservation discount up to $3.32 for each month from 2009 to the present in which they used no more than 3,000 gallons. The credits were not received because of a coding error in the water billing system.

“We apologize to our customers for this oversight and understand the frustrations this news will cause,” Water Utilities Director Allison Strube said. “We are doing and will do all we can to return what is rightfully theirs to our current and former customers. At the same time, we are taking measures to strengthen incentives to conserve water and to ensure this does not happen again.”

Some customers who had received the conservation discount contacted the Water Utilities Department after noticing the credit was missing from their monthly bill. During their investigation, City officials unearthed an error in a handwritten, 48-page computer code that a former City employee created in 2006 to determine who receives the discount.

The City has begun the process of refunding active customers. If an account closes prior to all the credits being used, the remaining balance will be returned to the customer.

“We encourage any customer who has questions about this to contact us,” Strube said. “We are trying to be as open and transparent about this as possible. Again, we apologize for this mishap and are willing to work overtime to make the customers who were impacted whole again financially.”

The Water Utilities Department plans to soon present to the City Council for its consideration an ordinance that would reward customers who actively conserve water.

“Many of the customers who earn the discount currently are not actively seeking to do so,” Strube said. “They manage to earn the credit simply by circumstance, such as the case with a realtor briefly needing water service for an inspection or a single person living alone in a home. We want to create a robust conservation program that encourages our customers to actively take steps to save water.”

Online customers should seek new credit cards 

San Angelo water customers who made one-time online payments between June 17 and Aug. 16 are advised to contact their financial institutions and request a replacement card if they have not already done so.

The City has received the results of a forensics investigation regarding a breach last month to a vendor’s online water payment system. The investigation found that malware skimmed credit card information from the contracted vendor’s server from June 17-Aug. 16. Only online one-time payments – as opposed to payments automatically drafted from a credit card – were at risk. Credit card payments made via auto-pay, by phone or in person were not compromised.

“Replacing a credit card is a hassle; we understand and apologize for that,” Water Utilities Director Allison Strube said. “But we would much rather that inconvenience not be compounded by customers also having to clear unauthorized purchases. We have worked with our vendor to prevent this from happening again.”

Upon learning of the breach, the City disabled all but phone credit card payments until the vendor that processes online payments could update its software and transition to a more secure platform. Online payments at were restored Aug. 21.

Customers were advised last month to monitor their credit card accounts for unauthorized charges. Many customers were forced to seek new cards after experiencing unauthorized purchases. Those who did not are still advised to request a replacement card. Skimmed credit card information is often sold well after a breach occurs; illegal purchases may appear weeks or months later.

A letter will be mailed to all customers who made online credit card payments explaining the compromise to the one-time online transactions. The breach did not increase the amount of a customer’s monthly bill.

Understanding your municipal services statement

The municipal services statement you receive monthly from the City of San Angelo includes fees other than water. Depending upon a household’s usage, water fees can represent as little as 35 percent of the monthly bill, with charges for trash service, storm water and sewer accounting for the balance.

Here’s a line-item primer for each of the charges that appear on a residential statement:

  • Trash service - provided by Republic Services, with whom the City contracts for trash service and landfill operations.
  • Trash sales tax - 8.25-percent sales tax applied to trash service charges. 
  • Storm water fee - determined by the amount of impervious area on a property – typically roofs, driveways, patios, walkways and sidewalks – that contribute to rainwater flowing into the storm water drainage system.The fees help fund City efforts to meet federally mandated regulations for maintaining those systems. Storm water fee rates are tiered. As impervious surface area increases, a higher rate applies. The average residential homeowner pays $3 or $4 per month.
  • Sewer base fee - determined by the size of the customer’s water meter. The fees fund the operation of the wastewater sewer system. Most residences have a meter that measures five-eighths of an inch and currently pays $28.02 per month. Of that amount, $4.64 is designated for capital improvements to the sewer system.
  • Sewer usage fee - based upon an average monthly water usage during December, January and February. Customers who average more than 4,000 gallons per month during that span pay $3.54 for each additional 1,000-gallon increment.
  • Water base fee - determined by the size of the customer’s meter. A residence using a five-eighths of an inch meter (the most common size) pays $26.68 per month with $3.32 designated for water-related capital improvements. Water main replacements, Hickory Aquifer infrastructure and fees related to exploration of other potential water sources are examples of capital improvements.
  • Water usage fees - determined by two factors: how much water a customer uses and what drought level the city is under. The water rate structure is tiered; as a customer uses more water, he pays a higher rate.

Water customers who live outside the city limits pay 1.5 times the rate paid by city dwellers.  Water usage is billed in 1,000-gallon increments. If a new customer uses 1,500 gallons of water the first month, charges are for 1,000 gallons that month.  The remaining 500-gallon balance rolls forward until it reaches a 1,000-gallon increment. If the following month the customer used 1,500 gallons, the charge is for 2,000 gallons of usage. For each 1,000 gallons billed, 95 cents is allocated to the water capital improvement fund. Each mailed bill includes a memo box noting the amount dedicated to water and sewer capital projects.

Other municipal service charges you should know about:

  • A 15% late fee if not paid within 25 days of the billing date. Payments made after 5 p.m. apply to the next business day.
  • A $25 fee for returned checks.
  • A $30 fee is required to reconnect service. Outstanding balances and fees are due prior to reconnection.
  • A $20 activation fee plus a deposit when an account is established. The amount of the deposit depends upon the customer’s credit history with the Water Utilities Department. The minimum deposit is $35. Deposits are refunded after a four-year period if the customer has no delinquent payments or service discontinued. 

Customers who pay their bills online at may note a difference between the online balance and the mailed statement balance. The online balance is a current balance and includes any changes to the account since the statement billed.

A conservation credit applies to customers who use less than 3,000 gallons in a month. Ten percent of the base rate and usage fees credit the customer’s account in the following month.

Customers who have questions regarding their statement or their service are encouraged to call the Water Customer Service Division at 325-657-4323; visit our offices at the City Hall Annex, first floor, 301 W. Beauregard Ave., adjacent to City Hall; or email Customer Service Manager Petra Trevino.
