The capture and reuse of gray-water or black-water for use in a plumbing system often complies with ____________.

The capture and reuse of gray-water or black-water in plumbing systems typically falls under compliance with LEED (Leadership in Energy and Environmental Design) standards. LEED is a widely recognized green building certification program that promotes sustainable construction practices, including water efficiency measures.

In the context of plumbing, LEED encourages the responsible use of water resources and emphasizes the importance of recycling and reusing water to minimize waste and enhance environmental sustainability. Projects aiming for LEED certification often need to demonstrate that they incorporate gray-water systems and other water-efficient practices that help achieve specific points under the water efficiency category.

While local plumbing codes and health department standards regulate safe practices in plumbing and sanitation, LEED specifically incentivizes innovative practices around water reuse that align with its sustainability goals. OSHA regulations primarily focus on occupational safety and health, not directly on water reuse compliance in plumbing systems.
