The University of Kansas purchases electricity, natural gas, water, sewer and stormwater management and trash removal services from outside utility suppliers. The university does own and maintain the infrastructure used to distribute the electricity, steam and water to the many buildings on campus. Costs for purchased utilities in FY2006 totaled $10,372,694, an increase of about $1.7 million over the previous year. The cost increases are a result of rate increases, high natural gas prices and new construction on campus. Many steps have been taken to reduce the energy and water consumption on a per square foot basis.
