Gallons
None
A brief description of any water recovery and reuse systems employed by the institution:
Landscape zones are irrigated with City of Colorado Springs-supplied non-potable water, a combination of raw water from a local reservoir and treated domestic wastewater.
None
A brief description of any water metering and management systems employed by the institution:
Every building on campus is separately metered for water use by the local utility. Primary irrigation systems are metered separately.
None
A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:
In general, Colorado College has phased in efficient water fixtures as older ones have retired. Fixture retrofits have included outfitting existing faucets with low-flow faucet aerators, replacing shower heads, replacing tank and flush valve toilets with low-flow models, and upgrading urinals to current standards. In 2012, while renovating Worner Student Center and Rastall Dining Hall, the College replaced the existing dishwasher with a more efficient one and retrofitted toilets and urinals with low-flow units.
None
A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:
The Facility Life Cycle Design Guidelines for Sustainability (2010) states that “opportunities for achieving… water reductions should be identified by design and engineering professionals in every construction or renovation project and considered for implementation based on life cycle cost savings, impact on reaching carbon neutrality, and the importance of demonstrating social responsibility by supporting the college core values and taking a leadership role in nurturing the ethic of environmental sustainability”.
None
A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):
The Colorado College Long Range Development Plan prioritizes the use of drought resistant plant material low flow irrigation techniques wherever feasible. The grounds department uses drought-tolerant xeriscape plants in many campus landscape areas, while limiting grass to activity areas and sports fields. A centralized irrigation control computer provides efficient watering for the campus, and more than 95 percent of campus is irrigated with nonpotable, reclaimed water.
None
A brief description of any weather-informed irrigation technologies employed by the institution:
Since 2000, irrigation controls have been computer-based, with a controller clock in each zone connected to satellite clocks. Irrigation is dictated by information provided by an on-campus weather station installed in the fall of 2007 at Stewart Field. This station monitors humidity, rainfall, temperature, and wind speed. It also feeds evapotranspiration (ET) data to the irrigation computer, which sets an order and duration for watering in each zone accordingly.
None
A brief description of other water conservation and efficiency strategies employed by the institution:
The Facility Life Cycle Design Guidelines for Sustainability (2010) requires the installation of low flow water devices in all new construction projects. Furthermore, the College captures water from its bearing cooler and uses it for its flue gas economizer. However, because this water is not metered, it has not been included in the "water recycled/reused on campus" section above.
