The Los Angeles Department of Water and Power (LADWP) embarked upon a study to evaluate the feasibility of converting its disinfection
practice from free chlorine to chloramine. A field investigation was included in this
evaluation, which consisted of a partial conversion of the LADWP distribution system to
a chloramine residual. The study realized that the LADWP's large uncovered finished
water reservoirs pose the greatest challenge to a chloramine conversion because of
difficulties in controlling the chloramine residual in them. The study concluded that the
utility would benefit from the conversion; however, large open reservoirs must be
replaced or covered in order to maximize the benefits, and mitigate the operating
challenges of using chloramine to lower disinfection byproducts (DBPs) in the LADWP distribution system.
