With almost six-hundred sprinkler heads to maintain, rather than the seventy-six we had


previously, our workload will be similar to before, albeit with a different emphasis


New irrigation was needed in all parts of the golf course - greens, tees and, starting approximately 15m from the putting surfaces, approaches too.


With just under six-hundred new sprinklers going in, the course was set to see a seven-fold increase on its previous sprinkler count.


“The old system was proving difficult for the club to upkeep,” said Plummer. “They weren’t covering the approaches, and the


tees weren’t irrigated either so it was a very comprehensive renewal.”


Set just below turf level for easy mowing, the new Berkhamsted sprinkler system consists of computer-controlled Rainbird 751s and Rainbird 950 Eagles on the greens and approaches, with Rainbird 5004, 8005 and 550 series sprinklers around the tees. Back-to-back sprinklers were paired with a 200mm gap in between, for the greens and approaches, with tails also watering a


little behind the sprinkler in many cases. Roger Davey specified where each sprinkler should be placed, and what the bar pressure settings should be.


Additional quick valve coupling brass connections were also supplied at every green, so that club staff can provide additional irrigation or sprayer fill for any emerging hot spots.


The main line pipe installed was Polypipe 90mm HPPE SDR17 10 bar, with a DitchWitch
