Enhancing Safety and Sustainability at Sewage Treatment Plant Hesper with Tvilight’s Adaptive Lighting Solution

Overview

Sewage Treatment Plant Hesper (Hesperange), a key wastewater treatment facility in Luxembourg, sought to improve working conditions for its employees at night while preserving the local environment. To meet this challenge, Tvilight deployed its adaptive lighting solution, ensuring optimal lighting levels for nighttime operations and minimizing environmental disruption. Thanks to motion sensor street lighting, the facility now benefits from over 90% energy savings every night while promoting the preservation of bats and the natural nighttime ecosystem.

“The adaptive smart street lighting solution has transformed how we operate at night. It gives us the safety we need to work efficiently while protecting the environment around us.”Facility Manager, Sewage Treatment Plant Hesper

Key Objectives

  • Improve night-time working conditions with appropriate lighting.
  • Minimize environmental disruption, particularly for local bat populations.
  • Achieve significant energy savings by using smart lighting solutions.
  • Reduce light pollution around the facility.
  • Implement a system that adapts based on human presence.
  • Support Luxembourg’s broader sustainability and energy efficiency goals.

Customer Vision

Sewage Treatment Plant Hesper faced two key challenges: ensuring that its staff could work safely and efficiently during night shifts, and doing so in a way that was environmentally responsible. Traditional lighting systems were energy-intensive and posed risks to local wildlife, particularly nocturnal species like bats.

To address these challenges, the customer envisioned an intelligent lighting system that could provide tailored illumination only when needed, while remaining dim during inactivity. The goal was to ensure safety for workers without sacrificing environmental sustainability.

Right light at the right place at the right time ensures night-time safety, energy savings and preservation of local wildlife.

Solution

Smart motion sensor street lighting

Tvilight delivered a comprehensive adaptive lighting solution, powered by motion sensors strategically installed across the facility. This solution provided adequate illumination when human activity was detected and dimmed the lights when no motion was present, contributing to both energy efficiency and environmental protection.

The installation utilized Tvilight’s state-of-the-art outdoor lighting controllers and the CityManager platform, which allowed for remote monitoring and control. This system enabled real-time data analytics, fault detection, and energy usage monitoring, giving Sewage Treatment Plant Hesper full control over its lighting infrastructure.

The solution also integrated features to mitigate light pollution and promote the conservation of local wildlife. By dynamically adjusting the lighting intensity, it ensured that the surrounding ecosystem, particularly the bat population, was minimally disturbed.

Outcomes and Benefits

The implementation of the motion sensor lighting solution brought several significant outcomes and benefits to the Sewage Treatment Plant:

  • 90% energy savings every night, significantly reducing operational costs.
  • Improved worker safety through well-lit pathways and work areas, enhancing efficiency during night shifts.
  • Preservation of local wildlife, particularly nocturnal species like bats, by minimizing light pollution.
  • Enhanced environmental sustainability, supporting Luxembourg’s green initiatives.
  • Reduced maintenance costs with Tvilight’s remote monitoring and fault detection system.

We are proud to contribute to Luxembourg’s sustainability initiatives and set a benchmark for environmentally responsible industrial practices.

Heide JeukenCEO, Tvilight

Working at night used to be challenging due to insufficient or overly bright lighting. With an adaptive lighting system in place, we now have just the right amount of light exactly when and where we need it. It has made my job safer and more comfortable, and it’s great to know that we’re also helping to protect the environment around us.
