Water Conservation and Management Flashcards

Under the Envision framework, which credit category primarily addresses reducing net water consumption in infrastructure projects?

Answer: Resource Allocation (RA)

Resource Allocation (RA) is the Envision credit category that addresses reducing net water consumption and protecting freshwater resources.

Which Envision credit specifically focuses on reducing potable water use during the operational phase of an infrastructure project?

Answer: RA1.1 – Reduce Net Water Consumption

RA1.1 – Reduce Net Water Consumption targets reductions in potable water use during a project's operational life.

What is the primary goal of water recycling and reuse strategies in the context of the Envision framework?

Answer: Reduce dependency on potable water sources

Water recycling and reuse reduces dependence on potable water supplies, conserving freshwater resources for both ecological and community needs.

Which metric is most commonly used to evaluate a project's net water consumption under Envision credit RA1.1?

Answer: Percentage reduction from a baseline potable water use

RA1.1 evaluates performance as a percentage reduction in potable water use compared to a conventional baseline project.

In sustainable infrastructure design, 'net zero water' refers to a project that:

Answer: Returns as much water to the watershed as it consumes

Net zero water means the project offsets its water consumption by returning an equivalent volume to the natural hydrological cycle.

Which on-site water source is most commonly harvested and treated for non-potable reuse in infrastructure projects?

Answer: Rainwater and stormwater runoff

Rainwater and stormwater runoff are the most accessible on-site sources harvested for irrigation, toilet flushing, and other non-potable uses.

Which design approach best supports freshwater resource protection by mimicking natural hydrological processes?

Answer: Installing low-impact development (LID) techniques

Low-impact development (LID) techniques such as bioswales, permeable pavement, and rain gardens mimic natural hydrology to protect freshwater resources.
