Industry brief

Clean Water Treatment & Supply

Control systems that keep water safe, compliant and flowing, around the clock.

What matters

What matters most

Clean water sites run day and night, many of them unmanned, under close regulatory scrutiny. Their control systems have to hold every treatment stage within limits, keep the network in supply, prove what happened and stand up to cyber threats, often on assets that have grown up over decades.

Water quality you can prove

Turbidity, disinfection and pH have to stay within limits at every stage, with alarms that act early and records the Drinking Water Inspectorate will accept.

Continuity of supply

Abstraction, treatment, storage and pumping must ride through faults, maintenance and power loss without interrupting customers.

Remote, unmanned sites

Works spread across a region rely on dependable telemetry, clear alarms and control rooms that see a problem before customers do.

Cyber security

As an operator of an essential service you must show NIS compliance, and control systems and remote access sit at the heart of that.

How we help

What we bring to Clean Water

On a live works, supply comes first. We plan changes around it with phased cut-overs and agreed fall-back positions, and prove new logic against a simulation of the process before it touches the plant. You get the design, code and method statements to run and maintain the system yourselves.

Standards

The standards that shape your project

The standards listed are those most often relevant to control-system work in this sector. Which apply to your project, and how, is agreed with you at specification stage.

Standard	What it covers	How we work with it
Water Supply (Water Quality) Regulations 2016	Drinking water standards, sampling and monitoring in England, enforced by the DWI (Wales has equivalent regulations).	Treatment control, alarms and data logging designed around the limits and records your compliance depends on.
WIMES	Water Industry Mechanical and Electrical Specifications, used across UK water companies.	We work to the WIMES documents and company appendices your project calls up.
NIS Regulations 2018 and NCSC CAF	Cyber security duties for operators of essential services, assessed against the Cyber Assessment Framework.	Segmented networks, controlled remote access and documentation that support your CAF evidence.
IEC 62443	Security for industrial automation and control systems.	Its zone-and-conduit model and security levels shape how we design control networks.
SEMD 2022	The Security and Emergency Measures Direction for water undertakers.	Resilient control design and clear recovery procedures that support your emergency planning.
IEC 62682 / ISA-18.2	Management of alarm systems for the process industries.	Rationalised, prioritised alarms so remote operators see what matters.
