- 17. 17 | © 2011 Kaiser Foundation Health Plan, Inc. For internal use only. February 11, 2016 Successes ▪ 2014: 26.7% reduction in water use even with an increase of 8000 patients at our facility (4% increase) ▪ Landscape water use – SMART controllers for landscaping: Sense the actual temperature of the weather and adjust accordingly. Sensitive to fog, rain, humidity, temperature and adjust watering amounts and frequency. – High efficiency nozzles for sprinklers and drip systems that use less water – Drought resistant planting – Campus fountains all use recycled water or have been shut off – It is anticipated that 3.2 million gal of water will be saved over the course of a year due to these projects
- 18. Additional Successes ▪ Cooling towers go through blow down after 6 cycles instead of 5 as in previous years. Therefore, draining of the cooling tower occurs less frequently leading to less wasted water. ▪ Replaced 40 year old boilers with new high efficiency boilers resulting in less water and energy usage ▪ Installed all low flow toilets and faucets in public bathrooms ▪ Green Team rounds looking for leaks and other opportunities ▪ Education of all managers on water conservation efforts and what they can do to get involved and assist with effort; e.g. full loads for EVS laundry, sterile processing, and dishwashing ▪ Expired water kept in storage for emergencies was used to water the grounds 18 | © 2011 Kaiser Foundation Health Plan, Inc.

- 19. Challenges ▪ Capitol investment for new landscaping controllers in additional locations ▪ Education/training staff to use new equipment ▪ Assessing the possible risk of too much mineral build up in cooling towers (test of change for engineering). No damage yet, may be able to take it even further. ▪ Broadening our educating staff and members to be mindful of water conservation in general ▪ Staff not reporting of leaks found in departments or public spaces in a timely manner ▪ Some other facilities are hearing complaints about not enough flow in the toilets/sinks ▪ Continued need to convert landscaping to drought resistant plants 19 | © 2011 Kaiser Foundation Health Plan, Inc.

- 20. 20 | © 2011 Kaiser Foundation Health Plan, Inc. For internal use only. February 11, 2016 Future projects ▪ Complete the test of change for cooling towers to see if can further increase the cycle number before blow down ▪ Keep water conservation in mind as we expand to 2 new sites and further increase our services and membership ▪ Installation of additional SMART irrigation controllers to outlying areas on our campus

Editor's Notes
- #1: Photo credit: Hermine Levey Weston, Iceland 2011. Practice Greenhealth hopes that this presentation will be used to frame the imperative for water conservation in health care.
- #2: Healthcare use: Water quality and availability are both essential to protecting patient health and critical to daily hospital operations. Water is used for everything from sanitation and instrument sterilization to heating and cooling. Water efficiency measures such as improved use of chiller condensate can save hospitals millions of gallons of water which translates into thousands of dollars saved. · Cost: Hospitals and clinics are saving $1,119,404 annually through conservation efforts. They saved > 275 million gallons of water in 2014 Source PGH benchmark report. · Water Pollution: Public health is impacted by high quality access to water for food production, sewage treatment and sanitation. Healthcare organizations can protect their communities by being good stewards of resources and responsibly handling chemical, pharmaceutical and solid waste streams. · Current water shortage and connections to climate change: Extreme drought in the Southwestern US is connected to climate change as well as historically poor stewardship of the resource. There is currently a negative feedback loop with water drilling and a decreased water table. In January 2014, Gov. Jerry Brown (D) declared a state of emergency over the drought and directed state agencies to take steps to prepare for water shortfalls. And a few months ago the State Water Resources Control Board adopted emergency regulations calling for a 25% decrease in overall urban water use across the state. Currently hospitals are expected to end landscape irrigation while most are working to improve water conservation in many areas. · Water and Food connections: Water shortages in the Southwestern part of the United States could be connected to food price increases or shortages. A patty of hamburger takes about 450 gallons of water to produce. It is important to consider water footprint for common goods used in hospitals such as meat, dairy products, fruits and vegetable, cotton and coffee. · Water Table Depletion: Public health and food security can be impacted by drilling for water in California which is causing underground water levels to fall dangerously low.. · Disaster preparedness: Healthcare organizations must have a supply of safe drinking water to maintain operations during natural or manmade disasters. · Opportunities for Improvement: According to the Practice Greenhealth 2015 Sustainability Benchmark Report, less than 30% of Partner for Change Award applicants conducted a water audit.
- #3: Virtual water for beef includes the water they drink and the water used to grow their feed and clean their waste. One hamburger is 634 gallons Virtual water for processed food includes water used to raise the animal and process the edible end product Virtual water for vegetables and fruit includes both rain water and irrigation Virtual water for cotton includes water used irrigate the crop and to dilute wastewater from fertilized fields plus water used to transform cotton into fabric.

- #4: Cleanable Area The actual surface areas of floors, walls, windows, sills, furniture, fixtures and equipment that require cleaning in order to maintain sanitary conditions and good appearance. Gross Floor Area (per ES) Gross Floor Area is defined as the total floor area, expressed in square feet or square meters, measured from the principal exterior surfaces of the building(s) and not including parking area(s)

This chart demonstrates that even top performers have opportunities in water conservation Photo credit: Hermine Levey Weston, Iceland 2011
- #7: This graphic demonstrates the water use from one hospital in New Mexico. A water audit is needed for each individual facility to ascertain water use. In general hospitals will use the 80/20 rule, focusing improvement attention on the largest users of water, but there is value in working with the lesser use of water. For instance, in drought stricken areas the public will not expect to see a hospital watering a lawn! This is where hospitals have changed the way they irrigate their landscape in order to meet regional water reduction requirements and community expectations, even though the actual water reduction is small in comparison with other areas.
- #8: The following slides were presented in the summer of 2015 in response to the water emergency in the state of California
- #9: These were goals for NorthShore University Health System, a 4 hospital system in the greater Chicago Illinois area.
- #11: These are impressive impacts of the planning, investment and execution of water management
- #12: Focus on Sterile Processing yielded impressive water savings at NorthShore
- #13: Water retention pond adds beauty as well functionality.
- #14: The following slides were presented in the summer of July 2015 to members of the Practice Greenhealth. They demonstrate the commitment of Kaiser Permanente to be good stewards of water in their drought stricken community.
