How does climate change affect water management in construction?

1 Water scarcity and drought

One of the most obvious impacts of climate change on water management in construction is the increased risk of water scarcity and drought. This can affect the availability and cost of water for construction activities, such as mixing concrete, dust suppression, and irrigation. It can also affect the performance and durability of construction materials, such as concrete, steel, and wood, which can degrade or crack due to water loss. To deal with water scarcity and drought, construction managers need to adopt water-efficient practices, such as using recycled or alternative water sources, minimizing water losses and leaks, and implementing water conservation measures.

3 Water-related hazards and risks

A third impact of climate change on water management in construction is the escalation of water-related hazards and risks. These include floods, storms, landslides, mudslides, and sea level rise, which can damage or destroy infrastructure, equipment, and materials, as well as endanger the safety and health of workers and communities. For example, floods can cause structural failures, electrical hazards, and mold growth, while storms can cause wind damage, flying debris, and lightning strikes. To mitigate water-related hazards and risks, construction managers need to conduct water risk assessments, design and build resilient and adaptable infrastructure, and implement emergency preparedness and response plans.

4 Water opportunities and innovations

A fourth impact of climate change on water management in construction is the emergence of water opportunities and innovations. These include new markets, technologies, and solutions that can enhance the sustainability and competitiveness of the construction sector. For example, water harvesting, storage, and reuse systems can provide alternative water sources and reduce water dependency and costs. Water-efficient and low-carbon materials and technologies can improve the environmental performance and lifecycle of construction projects. Water-sensitive and green infrastructure can provide multiple benefits, such as stormwater management, biodiversity conservation, and urban cooling. To seize water opportunities and innovations, construction managers need to explore and adopt best practices, standards, and policies that support water stewardship and innovation in the construction sector.
