A brief description of the institution's water recovery and reuse initiatives:

Agnes Scott is committed to using no potable water for campus landscaping, capturing stormwater from the entire campus in a retention pond that is used for landscape watering, except in cases of extreme drought or ensuring that newly installed landscape planting takes hold.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

Using the college’s nationally recognized Green Revolving Fund, the college has replaced almost all campus toilets, showers, and sinks with low flow fixtures in the past five years. The remaining plumbing fixtures in the Woodruff Athletic Center and several other locations will be replaced in Summer 2021. This savings of more than $150,000 will be returned to the Green Revolving Fund by transferring funds from the college’s utility budget until the projects have been paid back.
Agnes Scott’s trustees and staff committed to the highest efficiency HVAC choice available - geothermal - for two major renovation projects. Now 10% of the college’s 1 million square feet of usable space is heated and cooled with very little use of conventional electricity, no natural gas, and a decrease in water use for cooling estimated to be around 500,000 gallons per year for each building.

Data source(s) and notes about the submission:

Data reported for FY19 and for potable water only. The college utilizes a retention pond for landscape management, but since this pond is not metered, this non-potable water use is not tracked.
