Answer: D

Explanation:

Makeup water meters, conductivity controllers and overflow alarms

According to the Water Efficiency Prerequisite for Indoor Water Use Reduction, cooling towers and evaporative condensers must be equipped with makeup water meters, conductivity controllers and overflow alarms to reduce water consumption and prevent water waste. These devices help monitor and control the water quality, flow rate and level of the cooling system, and alert the operators of any malfunctions or leaks.

Reference: As per the LEED AP Building Design + Construction (LEED AP BD+C) V4 resources, the installation of makeup water meters, conductivity controllers and overflow alarms is a requirement for cooling towers and evaporative condensers under the Water Efficiency Prerequisite for Indoor Water Use Reduction. This prerequisite aims to reduce indoor water consumption by setting baseline and efficiency standards for fixtures, fittings, appliances, equipment and processes. For cooling towers and evaporative condensers, the prerequisite also requires efficient drift eliminators that reduce drift to a maximum of 0.002% of recirculated water volume for counterflow towers and 0.005% of recirculated water flow for cross-flow towers.
