Storm water from the streets of New Orleans flow to large drainage pumping stations where it is discharged into Lake Pontchartrain by means of long outfall canals. To reduce the coliform density, storm water was disinfected with sodium hypochlorite (NaOCl). Project facilities included manufacture, transportation, storage and feeding of 100 gram/l NaOCl. Sixteen high volume storms totaling 10 to the 9th power gal. of storm water were treated with more than 35,000 gal. of NaOCl. Long term fecal coliform levels were reduced by one order of magnitude in each outfall canal. (Modifed author abstract)
