A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:
---

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

We have rainwater cisterns in the Bateman and Workforce buildings. These feed toilets, a green wall, and a green roof.


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):

The college installs only waterless urinals and metered or sensor-driven faucets. Low-flow aerators have been installed. Low-flow toilets/valves were installed in the Arts building, replacing old high water usage toilets. The college installs WaterSense products where feasible. We also bought self-watering planters that store water and feed it up through the base, reducing water usage. The College has a sprinkler system on the athletic fields that runs on a schedule and has a moisture sensor.

Additional documentation to support the submission:
---

Non-potable rainwater is used in toilets in Bateman and Workforce, irrigating a green wall and a green roof, the enabling garden, and for watering plants. Assume 300 flushes/day in Bateman and 200/day in Workforce. Assume 1.2gpf and 240 days per year. For green wall, assume 5g every day. For green roof, assume 25 g/day for 3 months. For enabling garden, assume 25g/day for 3 months. For watering, assume 250g/week for 3 months. So total non-potable water usage is 144,000 + 1,825 + 3,000 + 3,000 + 3,000 = 154,825.
