  • unfortunately, and also deliberately we are not conscious to use water
    in moderate method mostly we are getting it almost free, we take serious caution to preserve gold which have no significance to lead daily life. but without water we can't live a day........ which is not necessary for us but for our loving descending generations.....

  • Aerators add air to the water stream to make the flow feel stronger. Laminar flow controls produce dozens of parallel streams of water producing a clear, solid-looking stream of water. Both give the feeling that water is flowing at a higher rate than it is. Water savings from high efficiency kitchen faucets is less likely because these faucets are often used for filling containers.
  • Open the cover for the water meter at the street to see the meter (screwdriver may be needed to lift the cover). Turn off the main shut off at the house. Verify the meter is not running. If it is running, there may be a leak between the meter and the house main. If there is no main shut off for the house other than at the meter, move to the second test. Do not turn off the water main at the street. Turn off the water main at the house and make sure all faucets and other devices are off and will be unused during this test. Note placement of the meter indicator. After 30 minutes, note if there is a change at the meter. If there is no change, there are no significant leaks.
  • The primary issue many cities are facing is insufficient stormwater capacity, the direct result of increased impervious surfaces: rooftops, streets, and compacted surfaces. Impervious surfaces directly correlate to light intensity as components of urbanization. As impervious cover increases, flood plain.

    • So we have it….
    Water Conservation
  • When We Need It
  • OBJECTIVES –
    • Learn to work with owner and design team to use water efficiently
    • Learn Green Guidelines and Practices
    • Get familiar with LEED, Green Points & other criteria related to Water Efficiency
  • Home Water Usage Opportunities
  • Domestic Water Efficiency
    • Distribute Hot Water Efficiently
      • Insulate Water Heater
      • Insulate Hot Water Pipes
      • Install On Demand Circulation Pumps
      • Locate Water Heater Within 12’ of Fixtures
    • High Efficiency Toilets
    • Water Efficient Fixtures
    • No Plumbing Leaks
  • Distribute Domestic Hot Water Efficiently
    • Locate Water Heater within 12 Feet of All Fixtures
  • Distribute Hot Water Efficiently
    • Insulate Water Heaters
  • Insulate Accessible Hot Water Pipes Distribute Hot Water Efficiently
  • Distribute Hot Water Efficiently
    • Install On-Demand Circulation Control Pumps
  • High Efficiency Toilets
    • Dual-Flush or maximum 1.28GPF
  •  
  •  
  •  
  • Water Efficient Fixtures
      • Toilets less than 1.28 gpf (use dual flush)
      • Showers use max 2.0 gpm
      • Faucets use max 1.5 gpm
  • Water Efficient Fixtures
    • Water savings from low flow lavatory faucets, used for hand washing.
    • Faucet aerators and laminar flow devices conserve water by restricting the water flow at the fixture outlet.
  • Showers
    • High efficiency shower heads may reduce demand for hot water and reduce energy use for water heating by up to 20%.
  • Water Heater
    • The water heater must be strapped.
  • Plumbing System Integrity and No Plumbing Leaks
    • Conserve water and prevent damage from leakage
    • Aspects of basic plumbing integrity include addressing plumbing leaks, the installation of water heaters and backflow devices.
    • Unknown plumbing leaks can damage the home and promote bacterial growth and waste resources and money.
    • Water heaters which are not strapped can result in significant damage in a seismic event.
  • Testing for Plumbing Leaks
    • Verify there are no leaks between the meter main at the street and the main shut off at the home.
  • Visibly Examine the Plumbing System for Overall Integrity
    • Look for small leaks and water stains that indicate current not historic issues throughout house.
    • Look for excessive corrosion on pipes that would constitute a leak or potential leak.
    • Conduct a toilet tank dye test.
    • Check the irrigation system for missing heads or other system leaks.
  • SITE DESIGN & WATER CONSERVATION REVIEW

    • Drought-tolerant Species
    • Minimal Turf Areas
    • Plants Grouped by Water Needs (Hydronizing)
  • Shade Trees
  • Drought-tolerant landscaping
  • Landscaping…..
    • 30-60% of an average home’s fresh water is used for watering the yard.
    • Good Practices:
    • High-efficiency Irrigation Systems
      • Drip, Bubblers or Low-flow Sprinklers
  • This…… Not this…..
  • Other Good Landscaping Practices:
      • Mulch All Planting Beds
      • Soil Amended with Compost
      • Rainwater Harvesting
      • Greywater Systems
  • Mulching
  • Water Catchment Filter
  • Rainwater Harvesting
  • Domestic Water Use
  • Greywater Systems
  • Greywater Systems
    • Benefits of Greywater Recycling For Irrigation
    • Reduce fresh water use - When the weather is warm, about half of the water consumed by the average household in North America is for outdoor use. Capturing the indoor greywater for use outdoors can cut water usage in half. Reduce strain on septic system or treatment plant - Greywater makes up the majority of the household wastewater stream, so diverting it from the septic system extends the life and capacity of the system. For municipal systems, decreased input means more effective treatment coupled with cost savings. Develop otherwise unsuitable real estate - A greywater recycling system, along with the use of composting toilets, can enable the development of property that is unsuitable for a septic system. Groundwater Recharge - Greywater recycling for irrigation replenishes groundwater, helping the natural hydrologic cycle to keep functioning.
    • Plant growth - Greywater can support plant growth in areas that might otherwise not have enough water. Maintain soil fertility - The nutrients in the greywater are broken down by bacteria in the soil and made available to plants. This helps to maintain soil fertility. Enhance water quality - The quality of groundwater and surface waters are much better preserved by the natural purification processes the greywater undergoes in the top layers of the soil than by any engineered water treatment. Satisfaction - The greywater user gets the satisfaction of direct participation in the responsible management of global nutrient and water cycles.
