Overview

• From June 1 to September 30, daytime irrigation for agriculture, green spaces, and sports facilities is prohibited when temperatures exceed 27°C, as measured at Langenhagen airport.
• Violators of the restrictions may face fines for administrative offenses, reinforcing compliance with the rules.
• Despite relatively wet years in 2023 and 2024, groundwater levels in the Region Hannover remain critically low, necessitating continued conservation measures.
• The Region has allocated €1 million in 2025 to support climate adaptation projects, with funding capped at €50,000 per project.
• Eligible projects include non-watering sports surfaces and greening initiatives aimed at reducing summer groundwater consumption.
