8. Ways to be Sustainable: Water Efficiency- Restrooms Depending on the ratio of male and female workers, replacing female toilets will probable be a better return on investment In male restrooms, replacing urinals will likely garner a greater savings than replacing toilets In general, men prefer to use urinals when available rather than toilets
9. Ways to be Sustainable: Water Efficiency- Aerators Standard Aerators 2.2 gal/min Water Saving Aerators 1.5 gal/min Saves up to 30% more water than a standard flow Maximum Water Saving Aerators 1.0 gal/min Saves up to 55% more water than a standard flow Compiled by Author form Sources: plumbingsupply.com Aerators are small but necessary parts of any faucet set up- They add air to make water flow in a more steady stream
10. Ways to be Sustainable: Water Efficiency- Graywater Systems Greywater is gently used water that has not come into contact with feces Toilet water and some washing machine water must be treated first before it becomes gray water Systems typically collect greywater in a large tank, filter and disinfect it, and then pump it back to flush toilets or to a drip irrigation system
11. Ways to be Sustainable: Water Efficiency- Graywater Systems It is often easier and more cost effective to treat all the waste water in one system – greywater and blackwater – on the commercial scale Most constructed buildings already have systems where the waste water is combined Most commercial buildings treat the water onsite with one of two methods: With a membrane bioreactor (MBR) system Or with a living machine
12. Ways to be Sustainable: Water Efficiency- MBR Systems Waste water can be reused for toilet flushing, irrigation, and cooling systems Treated effluent is of very high clarity and significantly reduced pathogen concentration Can reduce the fresh water taken from water supplies by over 75% and decreases energy costs The MBR treatment processes uses a perm-selective membrane (microfiltration or ultrafiltration) that is integrated with a biological process

14. Ways to be Sustainable: Water Efficiency- MBR Systems These systems tend to have smaller footprints Are especially effective at the biological removal of ammonia- nitrification MBR technology is not always the best treatment solution – it can be more expensive than other solutions Treatment of choice where high quality treated water is required and/or where space is limited
15. Ways to be Sustainable: Water Efficiency- Living Machines These systems mimic the processes of tidal wetlands to naturally treat wastewater They are designed to be easy-to-operate and are a self-contained system Most are small enough to be located entirely on site as the exterior landscaping and do not produce biosolids
16. Ways to be Sustainable: Water Efficiency- Living Machines Compiled by Author form Sources: architectmagazine.com Image Source: architectmagazine.com Sequential wetland cells are filled and drained with wastewater about 12 times a day- mimicking tidal ebbs and flows These systems use a primary settlement tank and planted wetland cells
17. Ways to be Sustainable: Water Efficiency- Living Machines Since wastewater entering into the system many have different concentrations, the system’s pump cycles can be adjusted Pump cycles can be adjusted daily if necessary Since there is no surfacing wastewater the potential for contact with human waste is eliminated Fans are also used to vent out odors
18. Ways to be Sustainable: Water Efficiency- Exterior Building There are three areas that building owners can focus on to conserve water: The Irrigation System The Landscaping A Rainwater Retention System
19. Ways to be Sustainable: Water Efficiency- Irrigation Two Most Popular Types of Irrigation Sprinkler Systems Drip Irrigation There is no one-size-fits-all water management solution Both methods serve different purposes depending on the unique needs of the property Compiled by Author form Sources: highgrove.net Image Source: Google Images
20. Ways to be Sustainable: Water Efficiency- Sprinkler Systems These systems are meant to emulate the effect of natural rainfall Water is distributed by a system of pressure-regulated spray heads and rotors Advanced head nozzles are used to break water up into small water drops that are dispersed through an efficient spray pattern
21. Ways to be Sustainable: Water Efficiency- Sprinkler Systems Advantages Covers larger areas Supplements minimal rainfall Uniform water distribution Easily automated Receptive to smart upgrades Spray patterns are adjustable Can be used for frost control Disadvantages Requires routine maintenance If equipment is damaged the system can make things inefficient or inoperable Uneven application from wind and extreme temperatures Water loss from evaporation Increasing the risk of disease and fungi growth Can damage building fixtures and cause slippery surfaces Compiled by Author form Sources: highgrove.net
22. Ways to be Sustainable: Water Efficiency- Drip Irrigation Surface Drip Irrigation • Irrigation network is above the soil • It delivers or “drips” water slowly, steadily and directly to the intended target • The soil surface, root zone or at the base the plant Subsurface Drip Irrigation • The system is burred under the soil • This technique can be even more efficient • This remove the potential for surface evaporation • Reduces the formation of weeds Compiled by Author form Sources: highgrove.net Image Source: Google Images
23. Ways to be Sustainable: Water Efficiency- Drip Irrigation Also known as micro irrigation It is a localized, low-volume form of irrigation Through a network of valves, tubing and emitters, this precise method has proven to reduce water and fertilizer usage There are two types of drip irrigation: Surface and subsurface
24. Ways to be Sustainable: Water Efficiency- Drip Irrigation Advantages Can be more than 90% efficient Incorporates into both new and existing landscapes Reduces soil erosion due to watering Uniform water distribution Fertilizer targeting is improved and run-off risk is removed Accommodates irregularly shaped or sloped landscapes Reduces plant disease risks Disadvantages Harsh sun can damage tubing •Tubing can clog •Cannot be used for frost control •Real-time watering can be difficult to observe Compiled by Author form Sources: highgrove.net

Ways to be Sustainable: Water Efficiency- Landscaping Not only during sub-optimal water conditions, but as a continual conservation effort Landscape water conservation integrates: Plant selection Plant adaptation Irrigation Management practices Compiled by Author form Sources: caes2.caes.uga.edu
26. Ways to be Sustainable: Water Efficiency- Landscaping The conservation of water through creative landscaping Originally developed for drought-afflicted areas There is no one single look for Xeriscapes- almost any style can be applied Compiled by Author form Sources: eartheasy.com Image Source: Google Images Xeriscaping
27. Ways to be Sustainable: Water Efficiency- Landscaping Compiled by Author form Sources: eartheasy.com Xeriscaping Benefits Saves Water Less Maintenance No Fertilizers or Pesticides Improves Property Value Pollution Free Provides Wildlife Habitat •Can reduce water use by 50 - 75% •Maintenance is minimal since watering requirements are low and can be maintained with an occasional pruning and weeding •Using native plants will eliminate the need for chemical supplements •A good Xeriscape can raise property values- This can more than offset the cost of installation •Fossil fuel consumption from gas mowers is minimized or eliminated •The use of native vegetation offers familiar and varied habitats for local wildlife
28. Ways to be Sustainable: Water Efficiency- Landscaping Compiled by Author form Sources: eartheasy.com 7 Principles of Xeriscaping Designs look for ways to reduce the amount of applied water to maximize the use of natural precipitation Water and Energy Conservation •Make use of the sun’s orientation by using north, south, east and west to your advantage and areas of sun and shade •Adjust the landscaping to the exiting geography rather that adjusting the geography •Use the position and location of plants to provide natural heating and cooling opportunities Ideal soil drains quickly and stores water at the same timeSoil Improvement •This can be achieved by increasing the amount of organic material in the soil and keeping the soil aerated Reduce the areas as much as possible while keeping some for open space, functionality and visual appealCreate Limited Turf Areas •Ask at the garden center for water-saving species adapted to the area Mulch helps retain soil moisture and temperature, prevent erosion and block out competing weedsMulch
29. Ways to be Sustainable: Water Efficiency- Landscaping Compiled by Author form Sources: eartheasy.com 7 Principles of Xeriscaping • Select plants that are native to the region and are drought-resistant plants. In general, these plants have leaves which are small, thick, glossy, silver-grey or fuzzy - all characteristics which help them save water • Select plants for their ultimate size to help reduces pruning maintenance • Have some trees help to reduce evaporation by blocking wind and shading the soil. Use Appropriate Plants • Drip irrigation systems offer the most efficient watering for xeriscapes because they deliver water directly to the base of the plant • It's best to water deeply and less frequently Irrigate Maintain your landscape
