2. Watering efficiently with appropriate irrigation methods

8. Step 1 -- Water day before audit

9. Step 2 -- Visually evaluate the lawn Why ?

10. Step 2 -- Visually evaluate the lawn Why? What?

12. Step 3 -- Visually evaluate flowerbeds, shrubs areas and other non-lawn areas What?

13. Step 4 -- Record current controller settings Will be used in end to compare water use before and after

28. Design criteria for uniform delivery Uniformity of water delivery = water savings Line-out along non-irrigated areas

29. Design criteria for uniform delivery Uniformity of water delivery = water savings Line-out along non-irrigated areas Don’t water onto non-irrigated areas

33. Step 6 -- While sprinklers are running, evaluate performance Repeat evaluation for each zone

34. Design criteria for uniform delivery Uniformity of water delivery = water savings

35. Design criteria for uniform delivery Uniformity of water delivery = water savings 1. Head to head coverage Spray from each head should reach neighboring heads 20% overlap gives better uniformity

36. Design criteria for uniform delivery Uniformity of water delivery = water savings 2. Fill in with heads in square and triangle patterns

37. Design criteria for uniform delivery Uniformity of water delivery = water savings Avoid pentagon (5 sides) patterns Dry spot created by head pattern

39. Maintenance criteria for uniform water distribution

47. Step 6 -- While sprinklers are running, evaluate performance Repeat evaluation for each zone

48. Step 7 -- Perform precipitation rate (catch can) test

53. Step 7 -- Perform precipitation rate (catch can) test Repeat for each zone

54. Step 8 -- Calculate run times for each zone

60. Work Sheet Question 1 Converting inches to minutes

68. Step 8 -- Calculate run times for each zone

75. Work Sheet Question 3 Observational Method

116. Design criteria for uniform delivery Uniformity of water delivery = water savings 3. Fill in with heads in square and triangle patterns. 1. Head- to-head coverage 2. “Line-out”
