PAYMENTS AND CUSTOMER SERVICE – As a safeguard against transmission of COVID-19, we ask our customers to first consider using our remote payment and customer service options listed here.   Customers wishing to make payments or talk with customer service inside our Main Office lobby should note the following restrictions:

  • Payments: No more than four (4) customers will be allowed into the building at any one time to make payments – this limitation may lead to lines outside the building.
  • Customer Service: No walk-ins will be allowed into the building except those who have called our customer service number at 956-430-6100 and scheduled an appointment.

YOUR WATER IS SAFE – HWWS remains committed to delivering safe drinking water to our customers during the COVID-19 pandemic. The normal disinfection process we use for water treatment is highly effective against coronaviruses, so rest assured HWWS’s water is safe.  For information from the Centers for Disease Control (CDC) on Water Transmission and COVID-19, please click here.

OPERATIONS CONTINUITY PLAN – HWWS follows the latest infection prevention recommendations of local, state and federal health officials, and we have implemented internal strategies to keep our employees safe and able to perform the essential operations that ensure your water supply remains safe and uninterrupted.
