12 Building Blocks Indoor Water Efficiency Questions to consider How low is too low? At what point do you sacrifice performance? What size appliances do I need? Building Blocks
13 Building Blocks Average of Total Indoor Water Use Other Leaks 6% Toilet 12% 26% Faucet 15% 18% 23% Laundry Shower
14 Building Blocks Indoor Water Efficiency Showerheads Residential Code gpm Showerheads gpm to 2.5 gpm low pressure/old pipes reduce flow Low flows can affect water temp Shut-off devices are available
15 Building Blocks Indoor Water Efficiency Faucets Residential Code gpm Faucets -.5 gpm to 2.5 gpm Is.5 gpm too low? low pressure/old pipes reduce flow Low flows can affect water temp Shut-off devices are available
16 Building Blocks Indoor Water Efficiency Toilets Residential Code gpf Dual-flush toilets -.8 to 1.6 gpf Pressure assist toilets 1.0 to 1.6 gpf Flapperless toilets 1.6 gpf
17 Building Blocks Indoor Water Efficiency Washing Machines Front loading vs. top loading Properly size the machine Moisture sensor is a must
18 Building Blocks Indoor Water Efficiency Dishwashers Older Dishwashers 7 to 14 gpl New efficient models 4 gpl Generally dishwashers use less water than doing dishes by hand. Again.. Consider proper sizing
19 Building Blocks Indoor Water Efficiency Heating water Traditional water heaters Solar water heaters On demand hot water - 4 year payback Tankless water heaters Check sizing
20 Building Blocks Outdoor Water Efficiency Informed site design and decision making Soil prep Turf choices Plant selection Using hardscapes Irrigation Creative rainwater use
21 Building Blocks Outdoor Water Efficiency Get to know your soil Test your soil ph, beneficials (micro nutrients and bugs) Soil probes root depth, soil type, water needs Add compost to improve soil nutrients and water holding capacity ( )
22 Building Blocks Outdoor Water Efficiency To Turf or Not To Turf Assess landscape uses/needs Create functional turf areas Alternative turf types Eco Lawn
23 Building Blocks Outdoor Water Efficiency Use hardscape features as a decorative elements
24 Building Blocks Outdoor Water Efficiency Plant Selection Right Plant, Right Place Know your Plants Needs Group plants with similar watering needs Map your Microclimates Sun and shade variations Soil variations Wind variations
25 Building Blocks Outdoor Water Efficiency General Irrigation Tips In the morning is most efficient No Irrigation Run Off Turf Irrigation Tips Lawns need 1 inch each week De-thatch and aerate to allow infiltration
26 Building Blocks Outdoor Water Efficiency The Hose & Watering Can Method Shut off nozzles for hose Soaker Hoses Drip Irrigation Flush system annually Match drip output to plant needs
27 Building Blocks Outdoor Water Efficiency Automatic Sprinkler Systems Monitor your pressure Proper Head Placement and Spacing System maintenance Flow Sensors Rain Sensors Efficient sprinkler heads
28 Building Blocks Outdoor Water Efficiency Weather-based Irrigation Controllers Use data from regional weather stations to set schedules One-way systems Two-way systems Site sensors Solar radiation, temperature, rain, and wind
