Demand Management
Integrated Conservation & Infrastructure Planning
The growing use of information technology has provided the water industry with
accelerating productivity and efficiency
gains over recent years. Customer
information systems, for instance, have
resulted in better control over revenues
and improved services levels, while asset
management systems have made preventive maintenance a practical reality.
Whilst reducing overall costs impacts both
capital
expenditure
and
operating
budgets,
the
capital
outlays
for
infrastructure are disproportionably high
by comparison. And they are constantly
driven higher by the need to develop the
supply facility to meet growing demand,
improve service levels and increase water
quality standards.
The key to resolving the paradox of
reducing costs in the face of growing
demand lies in the nature of the demand
itself. Effectively managing and reducing
the demand for water will reduce, or at
least defer, the need to overhaul the
water supply system,

Information sourced from both systems is
used in conservation and infrastructure
planning activities – aided mostly by a
disparate array of computer-based models
and hydraulic analysis tools. This
approach, however, lacks the necessary
integration to accurately analyze the
impact of demographics and land use on
future demands, and inevitably results in
static plans that are frequently out of date
before they are implemented.
Managing the Demand
Such systems, however, have proven to
be less effective in addressing the industry’s highest priority: reducing costs and
preserving water resources whilst meeting
increasing demand.

in Managing Demand
Most water services providers already use
systems that form the essential building
blocks of proactive demand management.

Summary of Main Features
Demand Management Data Model
• Commercial data – customers, connections, meters and meter readings
• Technical data – network components,
bulk meter readings, flow & pressure
• Reference data – town planning, tariff
structures, design standards, climate
Commercial Data Analysis
• Evaluates & validates commercial data
and reconciles with field surveys
• Identifies inconsistent data & consumption
categories, invalid meter readings/meters
• Identifies illegal/unrecorded connections
Technical Data Analysis
• Analyses network data topology, reconciles field surveys, corrects bulk readings
• Automatically defines demand zones by
linking with town planning
• Automatically defines network zones,
identify head & mass-balancing zones
Demand Analysis
• Analyses supply/consumption, translates
meter readings to continuous flows
• Uses design standards to generate design
flows for network analysis/capacity sizing
• Demand forecasting using variety of
techniques, incl. EPA guidelines
• Network component sizing based on conservation & design standard scenarios
• Monthly & real-time water balancing
