Technology that optimises
water distribution networks
THE IMPORTANCE
OF OPTIMISING
WATER PRESSURE
PRESSURE MANAGEMENT
CHALLENGE
BASIC PRESSURE
MANAGEMENT
+ Fixing pressure at the PRV outlet
+ Leads to excessive pressure 100%
of the time at critical point
+ Potential response: basic time & flow
modulation
+ Weak control of pressure vs target
+ Inability to respond and adapt to
changing network circumstances
ADVANCED PRESSURE
MANAGEMENT
+ Total visibility into network
performance
+ Remote management of pressure
+ Automatically and continuously
optimised pressure based on
demand patterns
+ Delivers the right pressure (and no
more) in the network all the time

Implementation
Time
LEAKAGE
REDUCTION
Syabas: 35.4 MLD reduction in 178 DMAs
+ Each percentage point of
pressure reduction in a water
network leads to a
corresponding decrease in
leakage
+ i2O’s solutions have reduced
leakage by 10 to 50% in
hundreds of water networks.
BURST
FREQUENCY
REDUCTION
Veolia Water UK installation
+ Minimizing pressure peaks
and softening fluctuations
reduces the frequency of
bursts
+ i2O’s solutions have
reduced burst frequency
by 40% or more in
customers’ water networks.
Before i2O
After i2O
LOWER
OPERATING
COSTS
+ Remote monitoring gives managers visibility to
network performance and events from any online
connection or location
+ Remote PRV control eliminates site visits to adjust
PRVs manually
+ Reduced leakage and bursts decrease need for
‘find and fix’ activity
+ Early detection of asset degradation reduces need
for routine maintenance visits
IMPROVED
CUSTOMER
SERVICE LEVELS
+ Many water networks’
service levels suffer during
peak demand, leading to
complaints and fines.
+ i2O’s solutions maintain the
right pressure, without abrupt
changes, minimising
customer service problems.
ENERGY
SAVINGS
APA Nova Ploiesti (Romania) installation
+ The lower the water pressure
you supply to a network, the
lower your energy
consumption
+ Installed on pumps with
variable speed drives,
Advanced Pressure
Management from i2O can
reduce energy consumption
by more than 20%
EXTENDED
MAINS
LIFETIMES
+ Many water networks are at or near their service
lifetimes
+ Burst frequency is the key trigger for capitalintensive pipe replacement investments
+ Reduced burst frequency significantly extends
pipe lifetimes

EXAMPLES
Manila Water
+ Serves more than 6 million
consumers in Manila, Philippines
+ 10 MLD pump station cut energy
consumption 24% on weekends,
14% on weekdays
+ Cut network leakage by 800,000
litres per day on weekends, 500,000
liters per day on weekdays
+ Radically improved level of service
from network pumps (failed daily
prior to i2O installation)
