HB 501 prohibits manufacturers, wholesalers, suppliers, or retailers from advertising disposable wipes as "flushable," "sewer safe," or "septic safe" unless the wipes disintegrate or dissolve immediately in water. It imposes civil penalties for violations, ranging from $1,000 for a first offense to up to $10,000 for repeated offenses. The bill also authorizes the Texas Attorney General to pursue civil penalties and injunctive relief against violators, with collected penalties directed to the state’s general revenue fund. The legislation is effective September 1, 2025.
