Wolfenbüttel's €25M water upgrade secures cleaner, greener supply for 53,000 residents
Wolfenbüttel has upgraded its drinking water system with a €25 million investment over the past decade. Two large reservoirs at the Drohnenberg site have been fully renovated to improve reliability and sustainability. The upgrades also include new solar panels on the roofs to cut energy costs and reduce emissions.
Over the last ten years, Stadtwerke Wolfenbüttel has spent around €25 million modernising its water supply. This funding covered climate-resilient storage, network upgrades, and a 15% reduction in leaks—outpacing similar towns like Salzgitter and Goslar, where investments have stalled at €18–20 million. The latest project focused on the Drohnenberg reservoirs, which now feature photovoltaic systems to generate clean electricity on-site.
Despite the improvements, challenges remain. Climate change, tighter regulations, and aging pipes put pressure on maintaining a steady supply. Future construction work may also lead to short-term water service interruptions. However, regular tests confirm that Wolfenbüttel's drinking water continues to meet strict legal quality standards. World Water Day highlights the need to protect water resources. Stadtwerke Wolfenbüttel's ongoing upgrades aim to secure fresh, clean water for the town's 53,000 residents long-term.
The renovations and solar installations mark a step toward a more efficient and eco-friendly water system. With €25 million invested, Wolfenbüttel has strengthened its infrastructure while cutting leaks and boosting resilience. Residents can expect continued access to high-quality drinking water, though temporary disruptions may occur during upcoming works.
