You will be able to save water by regularly maintaining your irrigation system. Test & Repair Test your irrigation system periodically to make sure it’s operating correctly.The irrigation system should be tested at the beginning of each irrigation system and again a minimum once a month or even during every maintenance visit cycle Make sure that all the sprinkler heads are working, and unclog or replace heads that are malfunctioning, broken, or missing. Clogged nozzles can cause dry spots in the landscape, and should be replaced with the same nozzle that is installed (consult the irrigation plan if in doubt). Leaking lines should be repaired and old nozzles with warped spray patterns should be replaced.Test drip systems for clogged filters or clogged emitters and leaks. When repairing leaks be sure to FLUSH the line after each repair. Adjust Heads Heads can be moved by collisions with feet, cars and lawnmowers, so check them all frequently for alignment. Adjust heads so they’re watering only your landscape—not sidewalks, streets, or driveways. Sprinkler heads aimed at these surfaces waste money and water. It’s easy to align the stem and nozzle pattern with the plants or turf grass that it is meant to irrigate. Adjust sprinkler heads to be at right angles to the soil surface. Tilted heads throw more water to one side, causing dry spots. Make sure heads pop up above the turf grass canopy.It is not uncommon to have to raise heads a couple of times a year. Set Controller Set your SMART irrigation controller by following the manufacturer’s instructions. Different plants have different water needs, so make sure you know their water use (low,medium or high before setting the controller.You can adjust your SMART irrigation controller percent adjust settings so you’re watering with the correct frequency, even SMART irrigation controllers need to be adjusted to site conditions. Plants tend to need less water during cooler weather, when their growth has slowed and water evaporates more slowly. Consider turning the controller off during the summer rainy season.

Many times, we’re over-or under- watering our lawns or plants without knowing it.Call in a Certified Landscape Irrigation Auditor to conduct a calibration test once every 3 years or so. Repeat Regular irrigation system maintenance will save you money in water bills and in large repairs that result from neglecting the system. Use these tips as a guide to worry-free irrigation! 01/03/2019 Page 10 of 15 Waste Water from Typical Irrigation Inefficiencies Waste Water from Typical Irrigation System Damages Mobile 209-404-1746: Email abolt@architecturalsolutions.us.com Irrigation System Maintenance Checklist Irrigation System Maintenance Completion Date: ________________ Address: _________________________________________________ The following items have been provided and explained to the irrigation system owner or systems owner’s representative. □ The manufacturer’s manual for the controller. □ A seasonal watering schedule. □ A list of components that require maintenance and the recommended frequency of maintenance are attached.

Irrigation System: □ Winterization – Plan to perform this around: ____________ (Drain the irrigation system, reprogram automatic controller.) □ Return to normal service – plan to perform this around: ____________ (Check to make sure there has been no damage to the system, reprogram automatic controller.) Sprinkler Heads: □ Missing or broken heads? (Replace heads with the same type of head.) □ Heads Clogged? (Remove the head and clean the filter or replace with the same type of head.) □ Heads tilted, spraying in the wrong directing, or too far in or above the ground? (Adjust or replace.) □ Leaking Water? (Replace a leaky valve in the valve box or check for a drainage problem.) □ Misdirected or blocked spray pattern? (Remove vegetation, trim grass, trees or shrubs, or other obstructions or consider raising the heads.) □ Spraying sidewalk, deck, building driveway or street? (Adjust the heads to stay within the planting area.) Controller: □ Is the cabinet or space holding the controller clean? (Clean out cobwebs, dirt, debris, or ants.) □ Is a new battery needed? (Consider replacing seasonally.) □ Is time/day showing correctly? (Reprogram) □ Is the controller programmed for the appropriate season? (Generally, plants need less water in the winter and mature plants need less water than newly installed plants. Refer to the seasonal watering schedule provided by your irrigator.) □ Is the controller programmed for any water conservation measures that may be in effect from your water purveyor? (Adjust program if needed.) 01/03/2019 Page 13 of 15 Sprinkler Heads: □ Fine Mist? (There may be excessive pressure on the spray zones. Possible fixes: Install a pressure regulator after the water meter; install pressure regulating sprinkler heads or valves.) □ Is the area being irrigated covered uniformly? (Possible causes: low or high water pressure, poor design, scheduling or installation techniques.) Controller: □ Wires loose or worn? (May be 110 volt.) (Tighten or replace.) □ Is rain or moisture sensor (or other technology) connected to the controller or ground wire? Valves: □ Replace broken or missing valve covers and valve boxes. □ Wire connections are intact and enclosed in appropriate moisture resistant connectors. Drip/Micro Irrigation: □ Emitters connected to flex line. □ Flex line connected to riser. □ Micro adjustment nozzle connected to flex line and nozzle intact. □ Service filter strainer periodically. □ Ensure proper operation of operation of automatic flush valves. □ Confirm operational pressures. Backflow Prevention Devices: **Note: You must be licensed to install, test or repair a backflow prevention device** Irrigation system owners should file a copy of any backflow test report with their irrigation system document. If you have a double check valve backflow prevention device, there is a “y” strainer in the water line. The strainer will need to be checked periodically. Water that is discharged from a reduced pressure principle backflow prevention assembly should be directed to sanitary or storm drains. The backflow prevention devise(s) should be protected from freezing. Irrigation system owners should have the backflow prevention device retested if above normal water velocities (such as a water system main break) occur. The backflow prevention device stops water from the irrigation system from entering into the water system. 01/03/2019 Page 14 of 15 Mobile 209-404-1746: Email abolt@architecturalsolutions.us.com AUDITOR PAGE# ANDREW BOLT DATE AUDITO 9 SUMMARY IRRIGATION WATER USE IRRIGATION SCHEDULING VII 01/03/2019 Page 15 of 15 4/10/19 Irrigation Schedule July Eto:6.50 45.3 Avg Plant Factor Et:0.4 Controller ET SOURCE Soil Type CLAY 0.2 0.81 Zone #Program Plant Type Plant Factor ET Plant Factor Plant Factor x Eto Root Depth " Shade Factor Density Factor Irrigation Type Inches Precip Rate % Dist Unif Irri Water Requirement Inches Total Period Run Time Valve Cycle Time Cycles Totals Days Per July Zone GPM Total GPM Total Run Days/Yr Total Gallons/Yr 1 A Shrub Low High 0.3 2.0 12 1 1 Inline Drip 0.44 0.9 0.33 37 18 2 8 2.4 89 51 4,502.73 2 A Shrub Low High 0.3 2.0 12 1 1 Inline Drip 0.44 0.9 0.33 37 18 2 8 2.5 92 51 4,690.34 3 A Shrub Low High 0.3 2.0 12 1 1 Inline Drip 0.44 0.9 0.33 37 18 2 8 1.2 44 51 2,251.36 4 A Shrub Low High 0.3 2.0 12 1 1 Inline Drip 0.44 0.9 0.33 37 18 2 8 2.3 85 51 4,315.11 5 C Pots Medium 0.5 3.3 12 1 1 Bubbler 1 0.85 0.59 19 5 4 12 14 268 76 20,341.18 6 B Tree Medium 0.5 3.3 18 1 1 Bubbler 0.44 0.9 0.56 62 21 3 8 0.42 26 51 1,313.30 7 A Shrub Low High 0.3 2.0 12 1 1 Inline Drip 0.44 0.9 0.33 37 18 2 8 0.8 30 51 1,500.91 8 A Shrub Low High 0.3 2.0 12 1 1 Inline Drip 0.44 0.9 0.33 37 18 2 8 6.5 240 51 12,194.89 9 B Tree Medium 0.5 3.3 12 1 1 Bubbler 0.44 0.9 0.56 62 21 3 8 10 616 51 31,268.94 10 B Tree Medium 0.5 3.3 12 1 1 Bubbler 0.44 0.9 0.56 62 21 3 8 8 492 51 25,015.15 11 B Tree Medium 0.5 3.3 12 1 1 Bubbler 0.44 0.9 0.56 62 21 3 8 9 554 51 28,142.05 12 A Shrub Low High 0.3 2.0 12 1 1 Inline Drip 0.44 0.9 0.33 37 18 2 8 1.8 66 51 3,377.05 13 A Shrub Low High 0.3 2.0 12 1 1 Inline Drip 0.44 0.9 0.33 37 18 2 8 12.3 454 51 23,076.48 14 A Shrub Low High 0.3 2.0 12 1 1 Inline Drip 0.44 0.9 0.33 37 18 2 8 1.3 48 51 2,438.98 15 A Shrub Low High 0.3 2.0 12 1 1 Inline Drip 0.44 0.9 0.33 37 18 2 8 3.2 118 51 6,003.64 16 B Tree Medium 0.5 3.3 12 1 1 Bubbler 0.44 0.9 0.56 62 21 3 8 4 246 51 12,507.58 Average Site % DU 0.90 172 Estimated Total Water Use: Gallons 176,749.90 IRRIGATION DAYS JANUARY FEBRUARY MARCH APIL MAY JULY AUGUST SEPTEMBER OCTOBER NOVEMBER DECEMBER TOTAL DAYS 1 2 4 5 7 8 7 5 3 2 1 51 1 2 4 5 7 8 7 5 3 2 1 51 1 3 5 7 10 12 10 8 5 3 1 76 CYCLES 2 MINS MINS 3 MINS MINS 4 MINS MINS MINS MINS MINS MINS 60 = MINUTES ET = EVAPOTRANSPIRATION (DAILY) Kc PLANT COEFFICIENCY PR = PRECIPITATION RATE EA = APPLICATION EFFICIENCY TOTAL SOAK TIME CONTRACTOR TO SET UP CYCLE SOAK ON ALL SCHEDULES OR MULTIPLE START TIMES.
