Workbook 3: Water Efficiency

MGD-13

 Introduction

Clean water is a necessity for human health and survival. It is critical that we take good care of this finite resource and not waste or contaminate it. The depletion of water supplies is costly, degrades the natural environment, and can threaten human health.

The environmental benefits from using water efficiently include building fewer dams, reservoirs, water treatment plants, and wastewater treatment facilities; and avoidance of the habitat degradation that accompanies surface water withdrawals.

Water conservation practices in a doctor’s office include the use of efficient appliances and fixtures, behavioral changes, and changes in irrigation practices. Together, these can reduce water consumption by as much as one third. The typical payback period for installing water-saving devices is three to seven years. In addition, energy use often goes down as well. These water and energy savings can have a significant impact on the doctor offices bottom line by lowering water, sewer, and energy bills, plus reducing maintenance costs. There is also the positive impact one makes in community that results from adopting and sharing water efficiency habits.

Changing water-use practices requires employee education. Changes to infrastructure, landscaping, and irrigation may require an initial capital investment, and a little time spent researching appropriate measures.

We offer 59 cost-effective water efficiency Action Steps and Education Steps for your Green Team to consider for your office. We suggest that you begin with the three”Quick Start, Now!” Action Steps listed in the next section.

Water Efficiency Action Steps

We will provide many proven and effective actions steps that you can adopt to reduce your officeís water usesage. Your Green Team will want to discuss these and then decide which action steps to complete. Your Green Team might design an entire water efficiency plan at the start, or simply choose a few action steps to get started, and then fully develop your plan after you have had success with your first steps.

The creation of your water efficiency plan should be a group effort because everyone on the Green Team will share the responsibility for making your plan work effectively. The water efficiency issues are divided into four sections listed below in the Advanced Route section.

We also will challenge your Green Team to come up with your own ideas by asking you, “What else?” Please email us your “What Else” ideas for us to add to the workbook.

Water Audit

How much water does your office use?  What are the major uses?  Where is water being wasted?  Begin your water efficiency project with an audit that assesses your workplace’s current water use.  Then your Green Team can explore water efficiency opportunities.  You can perform your own office water assessment or obtain outside help through free water audits from your local utility or online resources.

Green Fact: According to the EPA, Retrofit studies conducted in Seattle, Washington, and East Bay Municipal Utility District in California have shown that a household can save approximately 570 gallons per year by replacing existing bathroom sink faucet aerators with high-efficiency 1.5 gpm aerators.

Create a Water Audit Team from your Green Team.  Consider including office members who are familiar with building operations, facility management, maintenance, housekeeping or landscaping.  Perform at walk-through survey to see who uses water and how water is used in your office. Assign a person to monitor each water bill for sudden rises in water use.

Perform at walk-through survey to see who uses water and how water is used in your office.
Collect data that may be relevant to your doctor office, using the worksheet provided with this workbook such as:

  • Water and sewer bills for the previous full year.  Many utilities provide this information online, including with graphs of your monthly consumption and costs.  If your building has many tenants, your landlord may be able to provide this information
  • Hot water bills, if available.
  • Water softener and water filtering costs, if applicable.
  • Water system annual maintenance costs, if applicable.
  • Equipment maintenance schedules, if available.
  • Learn the locations of your water meters.
  • List equipment that uses water:sinks, toilets, showers, machines and equipment.
  • Sources of drinking water:tap water?  Large-bottled water? Single-serve bottled water?  What are the costs for these sources?
  • Are we recycling water bottles and other containers after their use?
  • Learn the types of landscape, irrigation, and irrigation control systems.
  • Faucets:  Check whether your office has water efficient, low-flow faucets.  The flow rate, in gallons per minute (gpm), is often imprinted on the rim where the water comes out of the faucetand may read something like “2.5gpm”.  The US Environmental Protection Agency (EPA) recommends a flow rate of 1.5 gpm or less for faucets.
Check whether your office has water efficient toilets and urinals.  For toilets, the liters per flush (lpf) or gallons per flush (gpf) rating should be marked on rim of the toilet bowl. If you cannot find any indication, likely it is not an efficient device.  Toilets should use 1.6 gpf or less.  Dual-flush toilets, that allow the user to choose between a flushing liquids or solids, use 0.8-1.1 gpf for liquids.  Many green buildings install waterless urinals that use zero water!

 List any current water saving measures that your doctor office has adopted. List any leaks that you discover. Check under sinks and around tubs, showers and toilets. Look for drips, drops or stains.

Select a water reduction goal (we offer 2 options):
A.  Reduce water use by 30%,   or   B.  Qualify for a LEED credit.  LEED (ìLeadership in Energy and Environmental Design) is a nationally-recognized green building standard that was developed by the US Green Building Council (USGBC).  Due to the complexity of the LEED standard, we recommend that you hire a consultant if you would like to pursue LEED certification.

  • The credit for “Fixtures and Fittings” is obtained by reducing potable water use of indoor plumbing fixtures and fittings to a level equal to or below the baseline listed in ìLEED 2009 for Existing Buildings: Operations & Maintenance.  The baseline is calculated assuming that 100% of the building’s indoor plumbing fixtures and fittings meet the plumbing code requirements as stated in the 2006 editions of the Uniform Plumbing Code (UPC) or International Plumbing Code (IPC).  Fixtures and fittings included in the calculations for this credit are toilets, urinals, shower heads, faucets, faucet aerators and metering faucets.  For a plumbing system substantially completed in 1993 or later throughout the building, the baseline is 120% of the water use that would result if all fixtures met the codes cited above.  For a plumbing system substantially completed before 1993 throughout the building, the baseline is 160% of the water use that would result if all fixtures met the codes cited above.
 Download and print the brochure, “Energy Conservation: Take It Home, Save Energy and Money.” Give it to your office staff and place copies in the waiting room.

Indoor Water Use

Your goal is to have the right equipment and to adopt habits of wise water use.
The 1992 United States Energy Policy Act established water efficiency plumbing standards for common plumbing devices. The American Water Works Association estimates that a savings of 6.5 billion gallons per day will be achieved in the US by the year 2025 through these standards. The standards set for maximum water usage are:

  • Faucets: 2.2 gpm @ 80 psi (8.3 liters per minute)
  • Toilets: 1.6 gallons per flush (6 liters per flush)
  • Urinals: 1.0 gpf (3.8 lpf)
  • Shower heads: 2.5 gallons per minute @ 80psi (9.5 liters per minute)

However, new water-saving devices can offer you much better efficiency than those listed above.

Adopt a purchasing policy to buy water efficient faucets, toilets, urinals, and other water devices when existing units must be replaced.

  • Install low-flow faucets (2.2 gpm or less).
  • Install low-flow faucet aerators: 0.5 ñ 2.5 gpm for lavatory sinks and 2.0 gpm or less for kitchen sinks. Aerators placed on the a faucet add air to the water flow so that less water is needed for washing. They are a cheap, practical alternative to replacing an entire faucet.
  • Install self-closing faucets. These are faucets that turn themselves off automatically after a few seconds. They may be activated by pushing down on a button or by infrared detection of the person’s hands. These cost from $50 to more than $200 per faucet.
  • Install faucet sensors on all faucets: These simple, battery-operated motion detectors are added to individual faucets in restrooms and kitchens to automatically turn faucets off after use, preventing unnecessary water use in restrooms and kitchens
  • Install and use waterless hand sanitizers at each sink if the practice considers it medically appropriate. Whether to do this is controversial and we do not make a strong recommendation for this Action step. Studies show that antibacterial waterless cleansers save water but do not clean any better than plain soap and water, plus they may lead to the development of resistant “super-germs” and put into the environment cleaning chemicals that are not so “green” themselves.

Adopt a policy to inspect and maintain water consuming devices (ice machines, washing machines, etc.) according to the manufacturers recommendations. Install permanent water metering system, if you don’t already have one, to measures the total potable use for the entire building and associated grounds. If possible, have a metering system that records your usage for each important task: indoor plumbing, hot water, cooling towers, irrigation, gray water, etc.

Install water efficient toilets and urinals and toilets. Ultra-low flow toilets use less water than the 1.6 gallons per flush (gpf) required by the US Energy Policy Act.Examples include “High Efficiency Toilets” (HETs) that use 1.3 gpf, and “Dual Flush Toilets” that use 0.8 gpf for urine and 1.3 gpf for solid waste. Ask your local water utility whether a rebate or tax credit is available for installing these devices.

  • Waterless urinals can save thousands of gallons a year and are very low maintenance with the need to change out the “no odor” cartridge only 2-3 times per year.
  • Replace existing urinal flush mechanisms with ones that flush at 1.0 gallon or less (as low as 0.125 gpf).
  • Convert some of your men’s restroom toilets to water efficient urinals.
  • Existing toilets: Install reservoir dams or a brick to decrease water use; inspect toilets periodically for leaks. Adjusting the flush value ñ a simple repair— is the most common way to fix a leak.

Using Equipment

Here are some additional ways you can reduce water usage in your office:

  • Adopt a policy to use water wisely in the office, using the ideas listed below.
  • Adopt a policy and habit of reporting leaks or examples of water wasting in your facility.
  • Adopt a policy for monthly inspection and repair of leaks in your facility. Leaks in toilet tanks can be found using leak detecting tablets, which may be available from your water company. Toilets are usually very easy to fix. For example, see www.toiletology.com or contact your building manager or plumber.
  • Decide to use city tap water instead of bottled water.
  • Provide reusable cups instead of disposable cups. If using disposable cups, use ones from biodegradable sources such as corn, or use cups from recyclable plastic (plastic types “1” or “2”).
  • Use “dry” floor cleaning methods, followed by damp mopping indoors, rather than spraying or hosing surfaces with water.
  • Change window cleaning schedule from regularly scheduled to “as required.”
  • Post signs in your restrooms and in the office kitchen to encourage wise water use (such as, ëPlease turn me off”, or “Please tell us if we leak or drip.”).
  • Avoid letting the water run if not needed, such as when washing dishes, brushing your teeth, washing your hands, or shaving.
  • Dishwasher and clothing washing machines: Use environmentally-friendly detergents. Scrape dishes rather than rinsing before putting them in dishwashers. Use the short or energy-saving cycles. Run machines only when full or at least use the small-load settings on these machines. New water efficient dishwashers only use 5-8 gallons. Check out www.greenerchoices.org for more ideas.
  • Turn off your hot water: Turn off the hot water machines for your entire building. This Action Step was researched and adopted in 2010 by the public health specialists of the Escambia County Health Department and found to be safe and to produce large savings of money and carbon emissions. Their five outpatient clinics care for complex patients including ones with serious infectious diseases, but they found that you do not need hot water for effective hand-washing.
  • Encourage office members to contribute ideas for water savings.

Outdoor Water Use

Did you know that about half of our drinkable water is used for home gardens, lawns and commercial landscaping?

Review your building’s irrigation schedule. Review and obey any local or state ordinances concerning outdoor water use.

Watering just once or twice a week is generally adequate. Water your landscaping during the coolest part of the day; early daylight hours is usually the best but follow the guidelines for your community and for each season. Avoid watering on rainy days and avoid watering on windy days due to higher evaporation rates.
Adopt a policy to inspect irrigation systems at least quarterly to detect and repair leaking or malfunctioning systems. Adjust sprinklers for proper coverage: optimize spacing and avoid over watering. Avoid spraying onto paved surfaces, and avoid runoff of irrigation water into the streets, alleys or gutters. Adjust the irrigation schedule according to each season’s needs.
These have deeper root systems and require less water than do lawns. Check with your local agriculture extension service for advice on the amount and frequency of watering needed in your area.

  • Install soaker hoses or drip irrigation systems that may use less water than sprinklers.
  • Install moisture sensors on sprinkler systems, or install rain shut-off devices or other controls that turn off the irrigation system when it is raining. Generally the best control systems are certified by the Irrigation Association’s (USA) “Smart Water Application Technology” (SWAT) program.
  • Use pressure reduction valves to lower the irrigation system’s water pressure to no higher than 50 psi ( pounds per square inch).

Collect rain water in rain barrels or cisterns for irrigating and other non-drinking uses. These are especially practical for backyard irrigation. Read more.

Use reclaimed, treated wastewater for irrigation, if available in your community.

Be certain that you have pumps that recycle the water. Post a sign to indicate that you conserve by recycling the fountain water. Use a timer to be certain that the pumps are turned off at night. Consider turning off fountains during droughts.

Install a shut-off nozzle on outdoor hoses to automatically shut off the faucet water if there is a break in the hose or if the faucet is left on accidentally.

Examine roof drain downspouts to be sure that they are directed away from concrete and foundation, and onto a permeable surfaces such as lawns and landscape areas to minimize runoff, rot, and flooding.

Planting Decisions

Choose the right plant for each location on your property, considering soil conditions, natural water drainage, and light. For each plant, consider its mature size, sun or shade requirements, soil and water needs, salt and cold tolerance as well as pH tolerance. Native succulents, sedges, grasses and flowers usually require less water, fertilizer and pest control than non-native species. Look into creating a rain garden and planting buffer zones to reduce runoff.

Have your soil tested for nutrient content; most communities have an agricultural extension office that offers this service at little or no cost; add organic matter if needed. Good soil absorbs and retains water better.

Reduce or eliminate lawn areas; uses native grasses and plants instead. If installing new lawn, use drought tolerant species and space sprinkler heads so that the water from one sprinkler head reaches the adjacent sprinkler head.

Use native plants in your landscape they often require less care and water than non-natives. Information on native plants is available at your local nursery, from your gardener, from your local agriculture extension office, and online.

Maintenance

Invite your landscape maintenance team to join your Office Green Team and consider these steps:

Use mulch around shrubs and garden plants to reduce evaporation from the soil surface and to cut down on weed growth. Mulch all non-turf (non-lawn) areas.

Raise your lawn mower cutting heights longer grass blades help shade each other, cut down on evaporation, and inhibit weed growth.

adopt a policy to minimize the use of chemicals such as pesticides and fertilizers. Speak with your maintenance company or local agricultural extension service for advice. Choose slow-release chemicals, which are less likely to run off your property into public streams and lakes. For fertilizers, examine each product label for the three-digit components of nitrogen, potassium and phosphorus. Be familiar with what is recommended for your soil type. For example, in northeast Florida, the first number (nitrogen) and the third (potassium) should be close to equal, and the middle number (phosphorous) should be no more than 2. Wise fertilizers for this region are: 15-0-15, 16-2-16, or 18-0-18. Avoid applying chemical before it rains as the rain can cause excessive runoff into streams.
Adopt a policy to use dry methods – not spraying with a hose – to clean outdoor hard surfaces. Consult your landscape maintenance team.

Community Education

Water conservation does not have to end with your office. Education your community is an important step in creating a greener environment.

  • Create a water efficiency “tip of the week” program.
  • Prepare informational handouts on for patients and staff on topics such as water conserving faucets, toilets and appliances; bottled water; and gardening methods.
  • Prepare a handout based on the online guide, “Forty-nine tips for saving water in the home“.
  • Prepare an informational handout on pesticide and chemical use.
  • Post a sign in your waiting room, restrooms and break room saying, “We conserve water for everyone’s health.”
  • Post a sign in restrooms asking users to conserve water and to report any leaks or drips.
  • Invite suggestions for water conservation from those working in the office and from your patients.
  • Add water efficiency ideas to your office website, newsletter, and bulletin boards.
  • Offer a prize for the best water-saving idea or action each quarter.
  • Publicize your action plans, accomplishments or setbacks. Seek feedback from those working in the office.
  • Schedule your water utility, agriculture extension office or a local non-profit to make a luncheon presentation to encourage water efficiency in the office and at home. Some water utilities offer free water conservation brochures or kits.
  • Develop, support or sponsor a community garden. Check with your agriculture extension office, city government, or garden clubs to learn how you can get involved.

What else? Please email us your “What Else” ideas for us to add to the Workbook. These suggestions will help you toward Green Doctor Office Recognition.

Tips for Success

Your Improvement Plan consists of the Action Steps that you choose to adopt for the office.

For each action step:

  • Record the conditions in your office before making improvements, such as your monthly water use. Record this on a Green Team Notes form or in a Green Team spreadsheet.
  • Establish specific, measurable targets for what you want to accomplish such as, “Adopt by December 1 a policy to inspect irrigation systems at least quarterly to detect and repair leaking or malfunctioning systems,” or “Install low-flow faucets on all sinks by June 1.”
  • Agree on a leader for each Action Step.
  • Agree on the responsibilities of each person in the office.
  • If needed, obtain agreement or approval from the office manager or chief executive.
  • Communicate with your office colleagues. Listen for ideas and try to elicit helpful criticisms.
  • Educate your patients, families & community. Which ideas could be shared with your own families or with your patients? Part of the Green Team Improvement Plan must include an education plan. Your waiting room can become a site for education.
  • Reassess the Plan after a reasonable period.

Background Information

  • Less than 3 percent of the earth water supply is fresh water, and much of it frozen in glaciers or ice caps. This leaves less than one percent of all the water on earth for our agriculture, industries, offices and homes.
  • Each year, global water use rises by 2 to 3 percent.
  • Florida receives, on average, annual rainfall of 50-55 inches, 67 percent of which evaporates or runs off the land into surface waters before it has a chance to soak into the ground.
  • Global climate change, due to the increased levels of greenhouse gases such as carbon dioxide, is expected to lead to warmer temperatures, a more active hydrological cycle, an increase in the water holding capacity in the atmosphere, and changes in rain patterns that are difficult to predict.
  • Compared to the amount of water we use in our homes and offices, more water is used to make the things we consume (such as food), and to generate the electricity that we use.
  • It takes 62,600 gallons of water to produce one ton of steel; 1,500 gallons to make a barrel of beer; 9.3 gallons to process one can of fruit or vegetables, and 3-4 gallons of water to make 1 gallon of bottled water.
  • The following are the number of gallons of water needed in California to produce an edible pound of:
    • Tomatoes: 23
    • Apples: 49
    • Milk: 130
    • Grapes: 70
    • Carrots: 33
    • Pork: 1,630
    • Potatoes: 24
    • Oranges: 65
    • Eggs: 544
    • Chicken: 815
    • Wheat: 25
    • Lettuce: 23
    • Bottled water: 4
  • A dripping faucet can waste 20 gallons of water per day, and a leaking toilet up to 200 gallons.
  • Storm drains are one of the worst sources of water pollution. Runoff of fertilizers, pesticides, and oil from landscapes and roads flows untreated into rivers and oceans.
  • Every drop of wasted hot water is paid for three times: once for the fresh water, once for the energy to heat the water, and once for sewer charges. Saving water also reduces expenditures for wells, pumps, water towers, and other water systems.
  • The Veterans Affairs hospital in Portland, Oregon found it saved about $17,000 yearly by using low flow faucets and shower heads, with an investment payback of less than one year.
  • Twenty minutes of outdoor watering can use 700 gallons of water for a typical home. Many native plants take much less water, fertilizer and time to maintain.
  • Most backyard plant problems are caused by excessive, wasteful watering.
  • “Reclaimed” water is wastewater that is partially treated and then reused. Reclaimed water is used in many communities to irrigate golf courses, commercial landscapes, sports stadiums, agricultural fields, and residential yards. It can also be used in industrial heating and cooling systems, for car washes, and to replenish wetlands during times of drought. Separate pipes are required to carry reclaimed water from the treatment plant to the sites of use.
  • The advantages of using reclaimed water include:
    • Saving drinking water supplies for use by homes and offices
    • Offers an environmentally responsible alternative to wastewater disposal
    • Reduces the need to construct new drinking water facilities
    • Reduces the need to transport water from other places
