Austin Water regulates all liquid waste haulers operating within the City of Austin's jurisdiction in accordance with City Code. Changes to these rules are proposed (see information under news items below). The wastes regulated include sewage, water and wastewater treatment plant sludge, and wastes from septic tanks, grease traps, grit traps and portable toilets. Austin Water also operates an approved receiving station for certain types of hauled liquid wastes. Managing these wastes and disposing of them properly are critically important to protecting health, public safety and the environment.
