The triple row system, or better said, multi-row system, because there are many situations where 4 and 5 rows are required, is part of the need. Small Hunter heads around the bunker complexes gives direct watering to slopes and surrounds, and when fescue is planted around the bunkers, the grass can be stressed by reducing applications of water to the bunker complexes and achieve that magnificent, rustic yellow look around the bunkers. Multi-row systems, where head to head coverage is aligned along the edge of fairway or primary rough, and wider spacing is used in the secondary rough just for grow-in, can reduce irrigation needs by 3,000,000 to 6,000,000 gallons a year in the northeast. The proper system requires about 2,200 heads, about $1,000,000 to $1,200,000 for ,materials and installation, and it gives excellent control over water use, aids in providing drier conditions, reduce pest stresses. Some balk at the price, but when it comes to infrastructure items liek irrigation and drainage you have to pay some money to save some money.
