I know it varies but even if I get an estimate figures it would be beneficial. 


below is my case study and you can figure out what kind of numbers are we talking about in terms of customers that way some figures/estimates can be made and some figures can be found close to that one.


Case Study: Digital Transformation at National Water Authority (NWA)
The National Water Authority (NWA) is a government-owned water utility responsible for managing
water supply, treatment, and distribution across Australia. Headquartered in Canberra, NWA
operates through regional branches in all states and territories, ensuring the delivery of clean, safe,
and reliable water to residential, commercial, industrial, and agricultural consumers.
NWA’s Core Responsibilities
● Water Sourcing and Treatment – Managing dams, reservoirs, desalination plants, and
groundwater extraction to supply clean drinking water.
● Water Distribution and Supply – Operating an extensive pipeline network that delivers water
across urban and regional areas.
● Sewerage and Wastewater Management – Collecting, treating, and safely disposing of
wastewater while ensuring environmental compliance.
● Infrastructure Maintenance and Asset Management – Overseeing water treatment plants,
pumping stations, pipelines, and storage facilities.
● Regulatory Compliance and Sustainability – Ensuring adherence to Australian water quality
standards and promoting sustainable water management practices.
● Customer Services and Billing – Managing customer accounts, metering, billing, and
dispute resolution for millions of households and businesses.
● Emergency Response and Drought Management – Implementing strategies to address
water shortages, pipe bursts, and contamination incidents.
Operational Structure
NWA has a highly decentralised operational model, with:
● Regional Water Treatment Plants – Ensuring localised water purification and distribution.
● Field Operations Teams – Engineers and technicians working on-site to repair leaks,
maintain pipelines, and upgrade infrastructure.
● Control Centres – Monitoring water flows, pressure levels, and quality using Supervisory
Control and Data Acquisition (SCADA) systems and IoT sensors.

● Customer Contact Centres – Handling enquiries, complaints, and emergency reports from
the public.
NWA currently relies on 50+ bespoke systems across various departments, including:
● Finance & HR – Legacy payroll, budgeting, and workforce management systems.
● Customer Relationship Management (CRM) – Disconnected customer service platforms
leading to inefficiencies in issue resolution.
● Assets & Works Management – Various standalone tools tracking infrastructure
maintenance, work orders, and asset lifecycle management.
● IT & Operational Technology (OT) Systems – SCADA, IoT-enabled sensors, and remote
monitoring systems that control water treatment plants and pipelines.
● Field Operations – Engineers and technicians use multiple disconnected systems for job
scheduling, asset inspections, and reporting, often relying on manual data entry and
paper-based records.
Due to fragmented systems and heavy reliance on manual processing, NWA is facing significant
operational inefficiencies, data inconsistencies, and cybersecurity vulnerabilities.
Digital Transformation Initiative
To modernise its operations, NWA has committed to a multi-year digital transformation programme
to replace its existing systems with a centralised, cloud-based enterprise platform. The new
solution will:
● Integrate Finance, HR, CRM, and Asset & Works Management into a single cloud-based
enterprise system.
● Improve data sharing, automation, and real-time analytics across departments.
● Enhance field operations by providing mobile-friendly access to asset and work
management systems.
● Strengthen IT/OT convergence by ensuring secure integration between corporate IT
systems and operational technology (SCADA, IoT sensors, remote monitoring, etc.).
The transformation is expected to improve efficiency, security, and service delivery, but also
introduces significant cybersecurity challenges that must be addressed.
Key Challenges and Cybersecurity Risks
1. IT/OT Convergence Risks
2. Cloud Security and Data Protection
3. Legacy Systems and Integration Security
4. Identity and Access Management (IAM) Challenges
5. Ransomware and Cyber Resilience
