Fugro supports renewal of sewer infrastructure in Leidschendam-Voorburg

Fugro has been contracted by the municipality of Leidschendam-Voorburg to perform integrated conditioning investigations for the municipality's sewer renewal program. This contract involves performing conditioning investigations for eleven sewer projects within the municipality. The project is part of the Implementation Plan for Sewer Projects (UPR), which aims to modernize essential sewer infrastructure and improve climate resilience.

The UPR takes an integrated approach to infrastructure renewal, combining replacement work with broader climate adaptation and sustainability ambitions. To support this, Fugro is conducting a conditioning study that brings together multiple disciplines. These include archaeology, geotechnical engineering, hydrology, ecology, environmental science and cable and pipe detection. This is being done in collaboration with project partners EARTH, Ploegam, Pius Floris and Aeres Milieu.

All research results are delivered via a digital twin environment: a virtual representation of the physical subsurface in which we integrate new and historical data. This provides the municipality with clear insight into important conditions in the subsurface, such as groundwater, soil stability, contamination and archaeological features. By identifying risks and challenges early on, the digital twin supports faster and more informed decision-making and enables timely interventions to address soil and groundwater issues. This ultimately contributes to more resilient and efficient sewer design.

"With our office based in Leidschendam for more than 60 years, this project feels like coming home to us," said Leo Zwang, manager of geoconsulting at Fugro. "It's a great opportunity to use our expertise in conditioning research to support the municipality's long-term goals. By providing accurate and actionable Geo-data through a digital twin, we are helping the municipality make future-proof choices for its sewer network with confidence."
