SFP Water Management & Conservation 2

Question 1

An SFP professional is evaluating a rainwater harvesting system. Which factor most directly determines the system's yield potential?

Accepted Answer

Local annual rainfall and catchment area size

Answer

Yield is fundamentally a product of how much rain falls and how large the collection surface is — greater precipitation and catchment area produce more harvestable water.

Question 2

Under EPA's WaterSense program, a certified fixture must use at least how much less water than the federal standard?

Accepted Answer

20% less

Answer

WaterSense-labeled products must be at least 20% more water-efficient than the federal minimum requirement while meeting strict performance criteria.

Question 3

Which irrigation strategy reduces evaporation losses and delivers water directly to plant root zones?

Accepted Answer

Drip or micro-irrigation systems

Answer

Drip irrigation delivers water at low pressure directly to the root zone, minimizing evaporation, wind drift, and surface runoff compared to overhead methods.

Question 4

A facility manager notices a 15% spike in water consumption with no change in occupancy. What is the most likely cause?

Accepted Answer

An undetected leak in the distribution system

Answer

Unexplained consumption spikes with stable occupancy most commonly indicate a leak — even small leaks in distribution lines can waste significant volumes over time.

Question 5

What is 'make-up water' in the context of HVAC cooling systems?

Accepted Answer

Potable water added to replace evaporation and blowdown losses in a cooling tower

Answer

Cooling towers lose water through evaporation and intentional blowdown; make-up water is the fresh supply needed to maintain proper water levels and concentration balance.
