Underground Infrastructure: Invisible but Essential

Underground infrastructure is invisible, yet indispensable. The network of cables, pipelines, and systems ensures the delivery of water, gas, electricity, telecommunications, and wastewater management. With growing demand for sustainable energy and climate adaptation, pressure on underground space is increasing. This calls for smart, sustainable, and safe solutions.

Underground infrastructure for TenneT

Our Approach

  • Planning and Design: Before excavation begins, we map existing underground infrastructure to prevent damage and delays.
  • Technology: Using ground radar and digital systems, we gain an accurate, real-time view of what lies beneath.
  • Sustainability and Safety: We install cables and pipelines with minimal environmental impact and ensure networks are climate-resilient.

Examples of Underground Infrastructure

  • Water pipelines and sewer systems – For drinking water and wastewater disposal.
  • Gas pipelines – Safety is paramount to prevent leaks and risks.
  • Electricity cables – Essential for energy supply.
  • Telecommunication cables – Fiber networks for high-speed connectivity.
  • Rainwater drainage and infiltration systems – Supporting climate adaptation and sustainable water management.

Frequently asked questions

Still have questions after reading this page? Find answers to frequently asked questions about underground infrastructure.

What is underground infrastructure?

Underground infrastructure includes cables, pipelines and systems that deliver water, gas, electricity, telecommunications and sewage. These networks form essential “lifelines” that support daily services and societal well‑being.

Why is underground infrastructure important?

Underground infrastructure is important because it underpins critical public services: clean drinking water, reliable energy, broadband connectivity and wastewater management. Modern society, economic activity and public health would not  function without these subsurface networks,

What challenges affect underground infrastructure today?

Rising demand for sustainable energy, limited underground space and climate‑related pressures make planning and design increasingly complex. Climate change and the energy transition intensify the need for resilient, future‑proof subsurface systems.

How is damage to existing cables and pipelines prevented?

Damage prevention relies on accurate pre‑construction mapping using technologies such as ground‑penetrating radar and digital utility maps. Correct identification of buried assets reduces excavation risks, prevents costly delays and improves safety.

How does underground infrastructure contribute to sustainability?

Sustainable underground infrastructure incorporates climate‑resilient design, water‑infiltration systems, and environmentally friendly materials. These approaches support long‑term resilience and align with international sustainability goals.
