A brief description of the institution's water recovery and reuse initiatives:
Condensate recovery program 1,734,223
Evaporation of water through central plant (goes through several cycles of use before it's evaporated) 137,211,048
These waste water gallons are handled through the university's cooling tower. Cooling towers are used to lower the temperature of the water before it is sent out to the campus. During that process a portion of the water is evaporated and thus never makes it to the back into sewer system. This system is a lot more efficient when compared to individual chillers. We have meters that calculate amount of water going in and out of the cooling tower. This allows us to calculate the amount of water that has been evaporated and not deposited back into the sewer system.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):
