HMWSSB Customer Care & Helpline Numbers
About HMWSSB support
HMWSSB lists at 155313 as its customer-care line, answered 24x7. Callers typically use it for account trouble, order or booking issues, refunds and service complaints. For anything that is not urgent, writing to customer-support@hyderabadwater.gov.in usually gets a written reply you can refer back to. If the service itself seems broken, glance at its live status page first — the problem may be an outage rather than something on your account.
