Water Management
Water management is facing major challenges - from water scarcity to extreme weather events. Green and cleantech solutions offer forward-looking solutions.
Water Management: Challenges and Solutions
Water management is a vital part of our daily lives - from water abstraction and treatment to distribution networks and wastewater purification. But climate change is increasingly confronting the water sector with new challenges.
New Challenges Posed by Climate Change
- Extreme weather events - such as heavy rainfall, droughts and flooding - are threatening communities and water infrastructure.
- Rising levels of pollutants require innovative treatment technologies to remove an increasing number of contaminants from wastewater.
- Wastewater treatment plants generate significant greenhouse gas emissions during the purification process.
- Water scarcity and low water levels call for sustainable concepts.
But challenges also create space for innovation!
Innovative Solutions for Sustainable Water Management
Green technology is enabling pioneering approaches:
- Sponge city concepts to retain and use rainwater efficiently
- Sewage treatment plants designed as biorefineries, using wastewater as a valuable resource
- Hydrogen production from treated wastewater
The water sector plays a vital role in sustainable development and is increasingly becoming a showcase for cleantech innovations – particularly where climate-neutral processes and energy efficiency go hand in hand.
Market segments in the Water Sector
Water management is divided into three key market segments, each facing specific challenges, but also offering innovative solutions. The GreenTech BW Atlas showcases numerous providers of green technologies in water management and highlights the strength of the region’s GreenTech sector.
Water Abstraction and Treatment - From Source to Tap
Rising temperatures and longer periods of drought, brought on by climate change, are increasing the demand for clean drinking water. At the same time, climate forecasts indicate that in some regions groundwater recharge could decline by up to 20% by 2050.
Key questions include:
- How can we ensure consistently high drinking water quality in the long term?
- How do we maintain a secure water supply amid growing demand?
- How can we keep water prices in Germany stable and fair?
Water Networks – Transport and Distribution
Water networks involve more than just transporting clean water from treatment plants to consumers. They also manage the removal of wastewater. This complex task requires reservoirs, kilometres of pipelines, pumping stations and intelligent control systems.
Key challenges include:
- Early leak detection and minimisation of water losses
- Smart network control for sustainable and energy-efficient water distribution that ensures constant pressure and high water quality
Wastewater Treatment – From Challenge to Resource
Sewage treatment plants are indispensable to modern society. Yet wastewater treatment involves both challenges and untapped potential.
- Climate-friendly processes: Greenhouse gases (e.g. nitrous oxide) emitted during treatment must be reduced
- Energy efficiency: Energy consumption should be minimised through optimised processes and the use of renewable energy sources
- Resource recovery: Wastewater as a resource – e.g. recovering phosphorus or utilising wastewater heat potential
