Water Conservation Projects

Projects completed or in progress:

• Single pass chillers removed and replaced with water conserving systems for Henderson Hall, Mechanical Engineering, UW Medical Center and the HUB, Tubby Graves, Physical Plant Office Building
• Clothes washers - efficient machines installed in student housing
• Irrigation - improvements continue to me made in various locations
• Sterilizers and air compressors in the Medical Center

Priority conservation opportunities proposed by Seattle Public Utilities

• Single pass cooling - Replace/retrofit 100 + air conditioners, chillers, ice machines and other single pass cooling (non-circulating).
• Medical and laboratory equipment - upgrades to sterilizers, tunnel washers, electron microscopes, liquid ring air compressors and vacuum pumps
• Other single pass systems - upgrades to fisheries and other single pass process water
• Fixtures - especially urinals and lavatory faucets
• Irrigation - system improvements

Engineering Opportunities

• Specifications - Review standards for new construction, new equipment and major remodels. Disallow installation of liquid ring compressors or vacuum pumps. (Excess water, sewer and energy costs attributable to liquid ring pumps often exceed, in a single year, the initial cost of the pump.)Update to specify installation of water conserving toilets, urinals, showers and lavatories.
• Cooling Towers - Develop and maintain a master list of all cooling towers. Log conductivity readings and maintenance problems at least monthly for all operating towers. Determine appropriate action for Cooling Tower BBX-17-03-04 in Health Sciences BB Mech. Rm. that is currently operating in single pass mode.
• Air compressors and vacuum pumps - Identify all liquid ring compressors and vacuum pumps. Evaluate the cost/benefit of replacement or addition of partial re-circulation kits. Include evaluation of 10 hp liquid ring vacuum pumps in Health Sciences BB Wing Mech. Rm. There are more than 20 liquid ring pumps on campus.

Housing and Food Services and Intercollegiate Athletics Opportunities

• Single pass ice machines - Identify and replace
• Single pass refrigeration - Identify and replace or retrofit
• Laundry - Install resource efficient equipment
• Fixtures - Install low flow shower heads. Replace high flow urinals with 0.5 gpf models. Install vandal resistant 0.f gpm aerators on all lavatory faucets
• Leaks - Survey restrooms for leaks and install new diaphragm kits in urinal and toilet flush valves to ensure excessive water is not used by existing fixtures.

Service Learning Students

Karley Kato and Colin Fissenden completed their Service Learning assignment during Spring Quarter. Their assignment was to develop and implement a means of elevating the awareness level of UW students regarding current energy conservation challenges and participation in energy conserving practices. Karley and Colin designed an energy usage survey questionnaire intended to query students about water consumption and the types of electric appliances and equipment they use and the frequency of use. The survey also provided useful appliance load information and philosophical incentive to reduce their personal energy and water usage. An information table was set up at McMahon Hall where the questionnaires were provided.
