INFRASTRUCTURE
Rats in the sewer are not just a nuisance; they are a risk to socially important infrastructure.
Critical infrastructure depends on stability. Whether it’s data centres, transport networks, wastewater facilities or utility systems, every part of society relies on continuous, reliable operation.
Rat intrusion, particularly through the sewer system, can compromise these essential functions, creating failures that impact thousands of people. Preventive protection is therefore not only a maintenance priority, but a matter of public safety.
Securing Continuous Operation in Critical Infrastructure
Utilities, data centres, and transportation networks rely on stable operations. Rats damaging cables and installations can lead to breakdowns with major consequences. With Nordisk Innovation, you get a solution that protects your facilities and society.
Rats entering underground installations can damage control units, cables, drainage systems, pumps and communication lines. Even small disruptions may have cascading effects throughout the infrastructure grid.
Nordisk Innovation’s rat blockers provide a high-reliability physical barrier inside the sewer system, stopping rats before they reach critical installations.
PROBLEMS
Typical rat problems in critical infrastructure
Rats threaten the stability of the system, especially by:
- Damage to cables, wires and control units
- Breakdowns and interruptions in supply
- Non-compliance with operational safety requirements
Increasing national focus on health, safety and hazard prevention
Legislation such as the Social Housing Act 2023, including Awaab’s Law, reflects a growing national emphasis on identifying and addressing health-related hazards quickly and proactively. From October 2026, this will also include pests. Although aimed primarily at residential environments, this regulatory shift highlights a broader expectation for public operators and infrastructure managers to minimise risks linked to pests, electrical hazards and system failures. By securing the sewer network with rat blockers, infrastructure operators strengthen safety, reduce operational risk and align with this wider preventive approach.
Understanding Rat Intrusion in Infrastructure Networks
Rats often enter infrastructure systems through:
- Sewer lines and stormwater drain
- Technical chambers and manholes
- Cable ducts and utility tunnels
- Underground ventilation routes
- Moist, waste-rich or hard-to-access areas
Because these networks are interconnected, rats can travel long distances unless a physical barrier is installed at key points.
Fire risk and damage to critical infrastructure wiring
Rats frequently gnaw on electrical cables, sensors and control components found in underground installations. This can disrupt traffic systems, disable pumping stations, interfere with signal control and compromise fire-protection equipment. In severe cases, damaged wiring may lead to short circuits or fire hazards within technical chambers.
By securing sewer access with rat blockers, operators can significantly reduce these high-impact risks.
Why Preventive Sewer Protection Matters
Infrastructure systems require high reliability. Traditional pest control does not stop rats from moving through underground networks; they must be blocked at the source.
A rat blocker ensures:
- Protection of sensitive systems
- Fewer emergency disruptions
- Reduced maintenance and repair costs
- Extended lifespan of cables and components
- Documented preventive action for audits

5 KEY STEPS
A proven method for securing critical infrastructure
Engineered for Demanding Environments
Nordisk Innovation’s rat blockers are made from acid-resistant stainless steel (AISI 316) and built for:
- High-flow sewer environments
- Wastewater chemicals
- Harsh technical conditions
- Manholes from 315 mm and larger
- Long-term durability and minimal maintenance
Supporting All Types of Infrastructure Operators
This strategy strengthens operational stability for:
