4.  Free source of water  Graywater  Supplement limited ground water  Low in minerals  Laundry, dishwashing, hair washing, and car  No chlorine  Garden ponds  Not regulated by municipal water restrictions  Periods of drought

5.  On average, Americans use 70 gallons per person per day  Toilets, showers, clothes washers, sinks, and other appliances  For each person, that’s about 500 square feet of roof + 1000 gallons of storage to meet these needs

6.  Today, 1.1 billion humans lack access to freshwater and 2.6 billion are without adequate sanitation.  By 2025 the developing world's demand for water will have increased by 50 percent

7.  Rodney Glass: “Man historically has treated stormwater and rainwater as a waste product.”  Tucson’s water demand is 147,000 acre feet/year while Tucson receives 185,000 acre feet/year of rainwater. It costs less money to harvest rainwater than to try to get rid of it compared to $300/acre foot to desalinate water. Desalinizing sea water costs upwards of $1,000/acre foot and has to be brought in from the coast.  On October 14, 2008, the Tucson City Council adopted a Commercial Rainwater Harvesting Ordinance which applies to new commercial construction. Facilities subject to the ordinance must meet 50% of their landscape demand using harvested rainwater, prepare a site water harvesting plan and water budget, meter outdoor water use, and use irrigation controls that respond to soil moisture conditions at the site.

11.  Rainwater harvesting systems have 4 major subsystems: Capture, Conveyance, Holding, and Distribution (non-irrigation systems will include Filtration and Purification

12.  Roof of the house  Keep debris out of the water system  Screens on gutters or downspouts

13.  Footprint of the building

14. Maximum Rainfall Rate  Based on 100 year data Charleston, SC  4.1” per hour  0.043” per square foot

15. Annual rainfall Charleston, SC  51.4”

16.  about.6 gallons per sq foot for 1” of rain  600 gallons per 1000 sq foot for 1” rainfall

17. Rain Chains

18.  Getting the water from the roof to the tank  Landscape piping moves water from the downspouts to the tank.  Gravity  https://www.youtube.com/watch?v=ssDIkR6 mN-0 https://www.youtube.com/watch?v=ssDIkR6 mN-0  https://www.youtube.com/watch?v=NHFXoh rysf8 https://www.youtube.com/watch?v=NHFXoh rysf8

25.  Each turn increases friction and reduces flow

26.  https://www.youtube.com/watch?v=LtWlSVh 2vTc https://www.youtube.com/watch?v=LtWlSVh 2vTc

29.  Bird feces, Plant debris, soil, eroded roof materials, and other solids

30.  Debris eater

32.  Wet versus Dry

33.  Dry

34. Dry line  Drain after rain

37.  Drain For Wet System

38. Wet line  Retain water in line  Require clean out

40.  Friction between the water and the pipe impede flow

45.  First flush

51. First flush diverter  Discards the initial runoff from a roof before it reaches the storage tank

52.  Ball or flapper shuts off the top of the pipe  Additional rainfall flows into tank

53.  Small-diameter outlet slowly releases “first- flush” water to empty for next rain

54.  Roof with minimal pollution  Capture 12.5 gallons / 1,000 square of roof  Heavily polluted roof  Capture 50 gallons / 1,000 square feet of roof

55.  POT FILTER captures rainwater from a single downspout  Normally buried and flush with the ground  The gravel strains out coarse debris  Filter mat smaller particles

56.  BASKET FILTER utilizes screen basket  Water flows in through a top port, through the basket, and out bottom port  A second port is provided at the top to allow overflow should the filter basket become full

57.  CASCADE FILTERS do not collect debris, but rather allow it to wash through the filter  Minimize maintenance  Lower water recovery rates  Rainwater cascades over a curved, multi-level screened filter  Filtered water exits through bottom port; debris is washed down the surface of the filter

58. Graf Quattro Twist Downspout Filter and Diverter

59.  VORTEX FILTERS are similar to cascade filter  Rainwater flows through the top port, spins around the circumference of the filter body, and spills into the top of the filter element.  Capillary effect draws water through the side walls of the filter exits through the upper side port  Debris washes down exits through the lower bottom port  Reduced capture efficiency, typically 85% to 90%

61.  Tanks  Storage System

62. SURFACE STORAGE  Free-standing plastic tanks offer the least expensive means of rainwater

66. Menard Multi-Purpose Building 30,000 Gallons

67.  Rain barrels

69.  Mosquito screen

71.  Gravity  0.433 psi per foot

72. Boerne Texas Champion High School gathers over 4.5 million gallons of water from parking lot run-off, roof gutters and air-conditioner condensation. - water is stored in elevated tanks and underground storm drains.

73. UNDERGROUND STORAGE  Unaffected by freezing weather, and can last indefinitely.  Cool, dark environment less chance for MO activity  3x as expensive as surface storage

77. Robert Redford Building Santa Monica, California

85. RainCavern  An underground chamber of plastic modules wrapped in a waterproof membrane  Virtually limitless storage in various shapes  Withstands vehicular traffic

90.  Collapsible tank

91.  Pump or gravity fed

92. FLOATING EXTRACTOR  Cleanest water in the tank is generally a few inches below the surface.  Intake suspended from a float  Rises and falls with the tank water level

96.  Inlet (calming effect)  Outlet at bottom  Overflow  Inspection Port  Vent

98.  Calming Inlet  Screen basket at inspection port  Overflow lower than inlet

109.  Pre-filtered rainwater can be used for landscape irrigation, garden ponds, and most exterior applications.  Toilet flushing and clothes washing, a sediment filter will remove suspended solids which can cause discoloration and odors  For showering, hand washing, or drinking, use a high-intensity ultraviolet sterilizer to kill microorganisms that could cause illness

110.  Connect in series

111.  Isolation valves

112.  Same size as inflow  Lid
