If the regulations required that any material put down the drain must have a pH greater than 2.0 and less than 12.5  in order to protect the aquatic environment and the bacteria in the local wastewater treatment plant  not to mention the pipe in the sewerage system.  There is two options to dispose of the acid safe and quickly:

a-Dilution

b-Neutralization to Na2SO4 and H2O with NaOH.
