What is a unidirectional flushing program?
unidirectional flushing program is a document that describes the steps to
follow to perform a complete unidirectional flushing. This program gives a
precise description of each operation to perform and their sequential order.
flushing sequence is presented on a file card that enables the technician to
proceed with the flushing and gather data on the condition of the network
components. The flushing sequences are designed to maximize the efficiency
of the flushing and reduce the customer’s inconveniences.
unidirectional flushing program simplifies the interventions of the
maintenance personnel. By indicating the sequential order of the operations,
it is possible to perform a complete flushing of an aqueduct system with a
minimum of interventions on the system, therefore significantly reducing the
costs and the water usage during the operation.
Why perform a unidirectional flushing?
All aqueduct network managers look for
premium quality water. They can reach this goal with a good maintenance of
their system and by a complete flushing of their water distribution lines in
order to eliminate mineral and biological deposits. The flushing allows
discharging any stagnant water from the water distribution lines and
therefore increases water quality.
The systematic flushing of an aqueduct
network is a demanding operation because of the complexity of the
manoeuvres. A minor error in the sequence of intervention can jeopardize a
whole section’s cleaning.
Even if the unidirectional flushing is not
the solution to all water quality problems of an aqueduct network system, it
certainly significantly reduces mineral and biological deposits on the
interior perimeter of the water distribution lines. Therefore it reduces the
hydraulic capacity loss of the water distribution lines.
