1 DO IT YOURSELF DRIP IRRIGATION SYSTEMS

2 WHY CONSIDER? No great skill needed to install No trenching required No electrical connections necessary No precise pipe connections to make Inexpensive to install

3 DRIP IRRIGATION ADVANTAGES Reduces loss through evaporation Eliminates runoff Does not spray leaves, petals, trunks thus reducing fungus potential Does not waste water irrigating surrounding areas (discourages weeds)

4 ADVANTAGES Reduces overall time to water a given area Ensures consistent moisture to individual plants Works especially well on difficult hillsides Can be used for small irrigation additions

5 MINOR PROBLEMS Occasional minor adjustments do to: Dogs chewing Children kicking Spider web clogging

6 PLANNING Planning is essential Draw a design to include all your plantings under consideration Determine the size and requirement of each circuit/zone About 200’ max per circuit Matches your needs to your purchases

7

8 PLANNING Think “HYDROZONES” Think drip and/or spray systems Sprayer systems for closely spaced systems Drip systems for widely spaced plantings Regardless, the system selected should cover 50% of the root zone Think about the soil type in your garden area

12 TOOLS & OTHER BASIC MATERIALS NEEDED Tools…cutters and punch Materials : Garden hose? Staking device

13 OPTIONAL UPGRADES Filter Timing device Fertilizer injector …needs anti-siphon valve All sorts of interesting toys

14 TUBING & FITTINGS ½” main tubing 2 wall thicknesses.052 and.060 match fittings to wall thickness 3/8” main tubing

15 TUBING AND FITTINGS FITTINGS (i.e. connectors) Used to connect pieces of tubing Fittings are color coded: Red fittings for 3/8” tubing Blue and green for 1/2” tubing Three insert types Compression Barbed locking

16 EMITTERS & SPRAYERS Emitters let the water drip onto the plant roots Generally come in three sizes ½ gallon per hour 1 gallon per hour 2 gallons per hour Have barbed ends to fit into micro tubing Color coded…color end into tubing Also sprayers in ¼, 1/2, ¾ and full turn Also available as a pre-constructed line with emitters attached

17 SOME ADDITIONAL ITEMS Punches Goof Plugs Stakes

18 Output rate Number of emitters Placement Vegetables - close spacing ½-1 GHP 1 Every 12” Vegetables -widely spaced 1-2 GPH 1 At base of plant Flower Beds 1 GPH 1 At base of plant Ground Covers 1 GPH 1 At base of each plant Shrubs 2-3 ft tall 1 GPH 1-2 At plant base Shrubs and Trees 3-5 ft tall 1 GPH 2 12” opposite sides Shrubs and Trees 5-10ft tall 2 GPH feet from trunk Shrubs and Trees ft tall 2 GPH feet apart at drip line Trees Over 20 ft tall 2 GPH 6 or more 4 feet apart at drip line

19 INSTALLATION Each main line (1/2”…large diameters) diameter has a maximum length…200’ Each micro line (1/4”) has a maximum number of emitters If possible try to connect emitters directly to the larger drip tubing lines.

20 DRIP TUBING Diameter Flow rate Maximum Length Polyethylene Tubing ½” 320 GPH 200 ft 3/8” 100 GPH 100 ft ¼” 15 GPH 25 ft Heavy weight vinyl ¼” 10 GPH 20 ft MAXIMUM TUBING LENGHTS

21 HELPFUL TIPS Allow ½” poly to sit in the sun Buy a good punch Measure twice …cut once

22 Maximum Number of Emitters To determine the maximum number of emitters on each line: For each ½” line add up the water volume of the emitters…maximum volume of emitters is 320 GPH For each ¼” micro line maximum volume is 15 GPH

23 FINDING A SUPPLY SOURCE Local Lowe’s and Home Depot Internet sources The Drip Store Sprinkler Warehouse Drip Works USA

24 QUESTIONS ?

26 WATER INFORMATION A typical area of 20’X40’ (800 sq. ft.) requires about 4000 gallons of water per month Garden hoses deliver: Dia. Hose Flow gal/hr Hrs of watering 1/2 “ hrs/mo 5/8” 500 8hrs/mo 3/4” hrs/mo
