This poster paper presents several key factors that
impact water age in storage reservoirs, including
distribution system/facility
operations, storage type and volume,
and the location of storage in
regard to the demand areas within
a distribution system.
Utilities that use chloramination for
final disinfection in efforts to minimize
DBP formation often experience
nitrification events in storage
facilities as a result of extended
water age.
Maintaining water quality in
distribution system storage facilities
has generally been observed with a
two-prong focus on mixing within the
tank and operational considerations to
maximize turnover.
Other factors that should be considered
of significant importance in new
construction are the location of the
facility relative to the system and the
type and volume of the facility.
Water quality problems may still exist
even with good mixing characteristics
in a storage tank, and improvements
required to reduce high water ages for
storage facilities located outside the
demand area can be expensive.
EPS modeling can be an effective
tool to identify the effect of storage
facilities on water quality in the
distribution system.
