Low-Flow Toilets and Showers
In the past few years, Concordia began installing low-flow toilets, showers and faucets.
Low-flow toilets use just over a gallon of water per flush – half the amount of water that standard toilets use. Furthermore, low-flow showers emit two-and-a-half gallons of water a minute compared to the standard four gallons per minute and, by reducing water flow, also reduce the amount of energy needed to heat the water.
By foregoing trays in the dining hall in 2009, Concordia saves a large amount of water. Each tray needs half a gallon of heated water to clean it. Each person will personally save almost 500 gallons of water annually. Every semester, Concordia saves approximately 200,000 gallons of water; enough to fill Prexy's Pond. This is in addition to other benefits, including cost savings and a reduction in food waste.
Long Lake property
Concordia recently constructed an eco-friendly classroom/lab on its Long Lake property near Detroit Lakes, Minn. The college also reshaped and protected the shoreline with natural plants. The newly landscaped area will serve as an example to the community of what can be done naturally to prevent erosion, while maintaining a beautiful shoreline.
Under the direction of several biology professors, about 45 species of plants native to this region were planted on the west side of Ivers Science Building. The native garden is primarily used by the biology department as a lab and research space for students. Classes can study the different plant species as well as observe the behaviors of the native bird and insect species that visit the space. Native plantings require no fertilizer, herbicides or pesticides, and little water to remain healthy. More so, they are very cost-effective and add biodiversity to campus.
Due to their adaptability in unpredictable climates, natural grasses stay green and crowd out weeds even in dry spells. The biology department hopes others will see the benefits of natural species and ask for plantings near their offices and classrooms.
Irrigation controllers are being converted to enable monitoring of environmental conditions such as rainfall, temperature, and water usage of the turf through evapotranspiration. This upgrade will reduce water use for irrigation.
