Our most important piece of equipment is our central control computer. It controls our 2500 heads on the golf course by calculating the Evapotranspiration Rate and managing the operation of each head through individual control. Each head can be adjusted in the computer using percentages to apply more or less water from that sprinkler head. All heads have been designed using triangulation which means each area will be watered by three heads surrounding it. The dry areas generally seem to show up in these areas and it is a balancing game to get all the areas watered enough for turf health but not too much for playability issues.
With that being said we have done major reprogramming to our computer this last winter to prepare ourselves for this season. We have balanced the percentages from rough to fairways since many rough heads were more than twice the percentage than the fairway heads that they were triangulated with. Using this method we were able to begin reducing the moisture along the perimeter of the fairways and spread it though the whole fairway for better playability and water savings.
The next thing we have done over the winter was to make our computer's dry run which estimates our nightly output to match our actual pump station out put by checking and reprogramming every head designation to match the type of sprinkler, nozzle and arc in the field. This gives us leverage when we are reducing water to know exactly how much we are cutting back.
Our last accomplishment with the balancing of the percentages in the computer has given us the ability to be much more accurate when we use ET. Over the summer the plant uses more water and in the past we could not water to match that usage. With the new balance we are watering much more accurately and it allows us to not only save water but put the water right where it is needed which gives us both playability and presentation.
The fact that we had one of the driest monsoon seasons in history and to have the course stay solid through the summer was a testament to our hard work. The history of running low on water was partially the fact that the water was not managed efficiently. The work that we have done has freed us up to concentrate on other problems. It also has given us the ability to manage the course with less man power since we have lessened the amount of handwatering needed by the crew. It has been great timing since we are under more pressure than ever with the falling economy. If we were unable to solve these problem The Rim Golf Club would not be the what it is today.

It’s great to know that you really make efforts in conserving water. Well, we should really be the ones to create solutions towards saving water because at the end of the day, we are also the ones who will gain benefits from it. Extravagant consumption of water must be avoided because the number of countries going through a water crisis is expanding. This could lead to a major challenge in the future, so we might as well take action immediately.
