To be consistent with the fiscal year information used answering other questions.
Water recycled/reused on campus, performance year:
Recycled/reused water withdrawn from off-campus sources, performance year:
A brief description of any water recovery and reuse systems employed by the institution:
Luther uses non-potable water captured from a rain gutter system to water potted plants across campus.
A brief description of any water metering and management systems employed by the institution:
100% of the buildings on campus have building level-water consumption meters.
A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:
As Luther renovates buildings, low flow faucets, urinals, and toilets are utilized. All new construction uses the most efficient devices possible.
A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:
A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):
A brief description of any weather-informed irrigation technologies employed by the institution:
All the irrigation systems with the exception of the Union have rain sensors that will shut off the system if it rains a certain amount. Most are set at 1/2 inch. The irrigation system at the Union was the first to be installed and has a different type of controller. We are looking into the possibility of installing the same clock and rain sensor as the other systems.
