What is described as the heart of the information system for water utilities?

• A. SCADA
• B. GIS
• C. CIS
• D. ERP

Answer: (A)

The main idea here is understanding what provides real-time monitoring and control across a water utility’s network. Supervisory Control and Data Acquisition, or SCADA, acts as the central system that collects data from field sensors (like pressure, flow, tank levels), allows operators to monitor those conditions on screens, triggers alarms, and remotely control equipment such as pumps and valves. This live, actionable information and control capability is what keeps the distribution system operating safely and reliably, and it’s what other systems rely on for context and data.

SCADA is the heart because it delivers the immediate operational visibility and command capability needed to manage the water system day to day. Without it, you’d lack the real-time telemetry and control essential for responding to events, maintaining pressure, detecting leaks, and ensuring water quality across the network.

The other systems are important but serve different purposes. GIS handles spatial and asset data, helping you map pipes and valves and plan maintenance. CIS focuses on customer information and billing. ERP integrates various business processes like procurement and finance. These systems benefit from data from SCADA, but they do not provide the live, system-wide monitoring and control that SCADA delivers.
