A brief description of the institution's water-related behavior change initiatives:

Western Technical College has plans to add signage about water usage in the residence hall. In September 2020, there will be tabletop stands throughout the residence hall about ways to be more sustainable, including ways to use less water.


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

A rain-barrel was installed in 2015 and is used in Western's Horticulture Center. A 15,000 gallon cistern of non-potable water is pumped in from the Business Education Center Condensate and collected from the roof drains. This water is used to irrigate the grounds and fill toilets. At the Sparta campus, a grey water system uses pond water to fill toilets and fire trucks to help with firefighter training.


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

During the $80 million referendum building projects, Western installed high efficiency plumbing fixtures and fittings in all new construction and retrofit projects. All shower heads in the residence hall have been replaced with low flow shower heads. Aerators have been installed on faucets to reduce the volume of water coming from faucets.
