What type of systems can earn points in the Water Reuse credit?

The Water Reuse credit in LEED focuses on the implementation of systems that capture and repurpose water, promoting sustainable water use within a building or site. Graywater systems, rainwater harvesting, and cooling tower condensate recovery are all effective methods of reusing water, aligning with LEED's objectives of efficiency and resource conservation.

Graywater systems take water from sinks, showers, and laundry to be reused for irrigation or toilet flushing, thus reducing the demand for fresh potable water. Rainwater harvesting involves collecting and storing rainwater from roofs or other surfaces for similar applications, effectively minimizing the use of municipal water resources. Cooling tower condensate recovery captures water that would otherwise be wasted from cooling systems, allowing it to be reused for irrigation or other non-potable uses.

These systems support the greater goal of reducing water consumption and increasing resilience in water supply, which is why they are specifically recognized in the Water Reuse credit. By implementing such practices, projects can earn points for their innovative approaches to water management, contributing to both environmental sustainability and operational cost savings.

The other options do not focus specifically on water reuse systems or do not align with the LEED criteria for earning points under Water Reuse. For example, desalination systems, while innovative in
