Cybersecurity and documentation support for remote pumping stations, telemetry, legacy PLCs, mixed vendor estates, and ageing SCADA platforms.
Water utilities operate critical infrastructure that directly affects public health, environmental protection and service continuity. Treatment works, pumping stations, reservoirs, chemical dosing systems, telemetry networks and wastewater sites all depend on reliable OT systems.
The cybersecurity challenge in water is often scale. A single organisation may operate hundreds or thousands of distributed assets, many of which are unmanned, remotely accessed and built around legacy control equipment.
Examples on this page are fictionalised, generalised or anonymised to show typical problem types without identifying real clients, real sites, real drawings, real systems or confidential project details.
Water OT estates often include a mix of old and new systems. Some sites may have modern SCADA and telemetry arrangements, while others still rely on older RTUs, local panels, radio links, cellular routers or vendor-managed equipment.
The result is often an environment where operations know the process well, but the cybersecurity evidence is incomplete. These issues become difficult when the organisation needs to evidence risk reduction, support a regulatory review, prepare for a project gateway or respond to an internal audit.
Water cybersecurity has several competing pressures. The work needs to be practical, repeatable and scalable across many site types.
Meridian Consultants helps water utilities review OT cybersecurity risks in a way that reflects real operational constraints.
The focus is on making the OT environment easier to understand, manage and evidence.
A useful review should help a water utility focus limited time and investment on the areas that create the most operational and assurance value.
Example scenario: A water utility required support assessing cybersecurity risks across remote sites where telemetry, PLCs, and SCADA systems were connected through mixed legacy and modern infrastructure.
The objective was to improve OT visibility, review remote access routes and produce practical evidence for project and assurance discussions without exposing sensitive site details.
