Relating to Class A water and sewer utility rate increases.

HB 1918 limits how often Class A water and sewer utilities in Texas can request rate increases and caps the maximum increase per ratepayer category. Specifically, it restricts rate increase filings to once every 12 months (down from 36 months), with exceptions only for financial hardship, and prohibits any single rate increase exceeding 20% for a specific class of customers. This directly affects large water and sewer utilities serving residential and commercial ratepayers across Texas. The bill applies only to rate increase applications filed on or after September 1, 2025.
