Work to utility piping systems must be permitted or have temporary authorization by Austin Water to discharge into the sanitary sewer system, even if the building has a wastewater discharge permit.
Utility piping systems include chillers and boilers used by commercial buildings, high-rises, schools, and universities to heat and cool the buildings. A permit is required to prevent certain cleaners, detergents, and corrosion inhibitors from leaching excessive chemicals and/or metals into the sanitary sewer system.
WORK THAT REQUIRES PERMITS
Cleaning and/or passivation of new utility piping systems
Cleaning, descaling, and/or coil cleaning of existing utility piping systems
