A brief description of the institution's water recovery and reuse initiatives:
---
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):
We have replaced our old toilets, from 4.5 gallons per flush to 1.5 gallons. Our new urinals also led to a 50% decrease in water use. We will soon be deploying an acid treatment in the cooling towers (which are the largest water user after irrigation) that will reduce water use significantly. This acid treatment will be applied in cooling towers at both sites, one that uses reclaimed water and one that uses potable water. This winter 2018 we will be replacing one chiller with a more energy and water efficient unit.
