When water leaves a treatment works and travels through a
distribution system, its quality, with respect to many chemical and
biological parameters, will degrade. The quality of the delivered
water will be largely influenced by: .The quality of treated water
supplied into the network .The condition of distribution assets
within the network .The retention time within the network. The
water industry has focused predominantly on the quality of treated
water and the physical condition of distribution assets when
improving the quality of water at the customer's tap. However the
quality of the water delivered is also affected by the time the
water is retained in the different elements of the distribution
network. Retention time is controlled both by the physical
characteristics of the system and the operational regime. Physical
characteristics such as pipe roughness may change throughout the
life of the asset or be modified by rehabilitation. Operational
activities may be structured; for example, pump scheduling and
planned maintenance, or uncontrolled as in the case of demand
driven operational responses. Changes to water quality result from
the reactions in the bulk water with time and through the chemical
and biological reactions with the distribution system materials
with which The chemical and biological reactions in the bulk water
are relatively well understood enabling development of models and
software for predicting changes. The reactions of the water at the
pipe-water interface are more complex and less well understood. The
aim of this research is to demonstrate that water quality within
distribution networks can be managed effectively by controlling
retention time and to develop practical and pragmatic methodologies
for doing so.
