The Foster Golf Links utilizes an automated irrigation system to keep the course's turf healthy and green. The irrigation controller system is set manually based upon the expertise of the Golf Maintenance Supervisor and estimates from the golf course's weather station. The system is limited in setting the frequency, duration, and cycling of the amount of water used. The entire golf course cannot currently be watered in one night. DISCUSSION The proposed irrigation computerized Central Control System will utilize the weather station data to put the correct amount of water needed for the various types of turf (greens and tees, fairways and roughs) based upon the temperature, humidity, wind, and evaporation rate. It will be possible to water the entire golf course in one night. The computer can cycle back through different areas (or controller stations) that have different saturation rates. An example of this would be a green that has a steep hill on it. The hill doesn't get enough water while the lower area gets too much water causing a puddle. By cycling through the station, the desired thirty minutes of water may be done in three ten-minute watering cycles. This allows the water to soak into the ground before the next application is applied. The Rain Bird Nimbus II irrigation computerized Central Control System is the only system that operates with our current weather station, irrigation controllers (clocks) and irrigation valves. The Nimbus II system includes: Course Monitor screen shows a graphical real-time view of the course with the ability to monitor activities at a glance. Rain Watch that suspends irrigation while simultaneously measuring the amount of rain that is falling to determine if the turf needs more water that night. Flo Graph allows visibility of real-time graphics of water used and pump activations. Flo-Manager balances system demand at maximum capacity with the efficiency of pump station and delivery network. Virtual Weather provides Rain Bird the ability to generate the evapotranspiration (ET) rates from the Weather Station [wind, humidity, temperature, solar radiation and rainfall]. Minimum ET uses environmental conditions to promote healthier turf by provide the proper amount of water needed by the plant (grass). Cycle + Soak works with Flo-Manager to achieve maximum efficiency and conservation. Water budgeting allows you to react to changing conditions with ease or to reduce the amount of water used. Smart Pump software links our pump station to the Central Control System providing real time communication and optimizing the irrigation cycle and reducing wear and tear on the pump. Smart Sensors stop a valve from operation ifthere is too much water flow (broken head or line) and sends an alert for the staff as needed repair for the next day. Rain Bird FREEDOM allows handheld two-way radio communication with Nimbus II to stop, start or continue water application. This allows staff to turn on and off the system to work on it during the day in between golfers walking by a certain area. In addition to the computer system and software, this project includes purchasing irrigation controllers need to be upgraded. This is simply done with a 'Retro Kit' that just change the face plate - instead of purchasing all new hardware for the controllers. Another part of the system's purchase identified above is the Rain Bird FREEDOM. This is a two-way radio that allows our staff to perform maintenance work throughout the course without having to physically turn on or off the clocks manually. The advantage of this is there can be 400 yards between where a repair may be need and the clock. With the two-way radio, a staff member doesn't have to drive over to the clock to do a quick line clearing flush of the irrigation line or head that they are working on. SOLE SOURCE The Rain Bird Nimbus II irrigation computerized Central Control System is the only system that operates with our current weather station, irrigation controllers (clocks) and irrigation valves. The Rain Bird Company only distributes their irrigation computerized Central Control System products through Horizon Irrigation stores. The Renton Horizon Irrigation store territory includes the City of Tukwila. This is the only store that we can make the purchase from and the only product that can operate our system. Therefore, the Rain Bird Nimbus II irrigation computerized Central Control System is the only system that operates with our current weather station, irrigation controllers (clocks) and irrigation valves. Please see the attached Horizon Irrigation Bid of $32,018.43, including tax, and a Resolution that authorizes the Sole Source purchase of the Nimbus II Computerized Irrigation System from Horizon Irrigation, Renton, Washington.
