UK Security and Emergency Measures Direction (SEMD) - Water Industry
The UK Security and Emergency Measures Direction (SEMD, 2022) issued by Defra (Department for Environment, Food and Rural Affairs) under the Water Industry Act 1991 establishes security requirements for water and sewerage companies in England and Wales. SEMD requires water companies to protect their infrastructure against threats including cyber attacks, physical security threats, and contamination. Water companies must conduct risk assessments, implement security measures, and maintain emergency plans. The Drinking Water Inspectorate (DWI) oversees drinking water quality security. Cyber resilience requirements align with NIS Regulations 2018 (and NIS2 transposition) as water is designated a critical national infrastructure sector.
