GILIESPIE HILL The 1979 reclaimation on Gillesie Hill is appearing 'successful. Alot of the seedlings are showing new growth and good health. The drip irrigation system was used weekly in mid-summer to increase their chance::6f::survival. DRIP IRRIGATION SYSTEM FOR ZINC HILL The 1500 gallon water tank on Zinc Hill could provide the evapo-transpiration needs of the 211 seedlings planted on section 3 this summer. A drip system similar to the one on Gillespie Hill would be effective. Before attempting to set up such a system the water tank and separators should be rinsed and flushed thoughly. This will remove moss which will clog the emmitter lines. The drip system itself would begin with a 112 inch line running from the tank directly down to the separators. Leaving the separators you would need 150 feet of 3~4 inch main line running vertically down the middle of section 3. Along this vertical main line you should place 75 foot 1~2 inch lateral lines. These laterals should be alternatly placed every 30 inches along the main line and remain a standard length to equalize the pressure throughout the system. On the end of each of the laterals ahd.~he,ma}n.bine,. should:be::placed a drain plug for flushing purposes. A 3~8 inch emmiter line should then run from these laterals to each and every seedling. A few inches of slack should be left in the emmiter lines. This will allow for expansion and contraction due to temperature changes. The average flow rate of .718 gallons hour for this type of system would allow 7 gallons of water per seedling over a 11 hour period. Providing the system was completely filled. I think a deep though w2teiigg like this once or twice a week will give Letter results then a more frequent shallow watering., 6
