Severe drought in 2017 presented the course with a significant challenge. After an unusually dry spring, Italy suffered its worst drought in 60 years, at one point placing 26 cities including Venice and Rome on the maximum extreme heat alert. Many of Rome’s fountains were turned off and the city narrowly averted drastic water rationing. A brutal August heatwave, ‘Lucifer’, saw temperatures soaring over 40º.
Castelconturbia has its own water source but scorching temperatures resulted in low reservoir levels, and lakes and wells that failed to refill. No surprise then that the course irrigation system struggled to cope and with water use capped, the quality of the course, play and the member’s experience were badly affected.
With temperatures 10-15% higher than normal and researchers predicting that summer conditions in southern Europe could get tougher in future years bringing spells of extreme heat, 2017’s summer drought was the spur that prompted the club to react quickly and decide to renovate its irrigation system.
Adriano Notarianni is Rain Bird’s Golf Sales Manager for Italy & Malta and explains:
“The motivating factor was having a more easily maintained system that would improve irrigation efficiency and provide robust defence against drought conditions. As part of the tender process, with combined input from irrigation consultant, Rain Bird’s technical team, the contractor and client, the project was divided into three phases with a clear plan for each of the three teams working on each phase and two of the four contractors who tendered agreeing to work collaboratively to hasten the overall project timeline. The first phase has just started, with final handover expected in late 2019, earlier than originally estimated.”
Irrigation consultant Lorenzo Simoni redesigned the new irrigation system for fairways, tees, greens and approaches, from pumping station through to rotors and comments:
“The club’s system would break down on a weekly basis as a result of issues with the hydraulic piping and the water pressure and the lack of a filtration system. Typically, the life expectancy of a system is around 20 years so this 30-year old system simply could not guarantee any degree of reliability.
We took into account the normal direct costs - the power, water, plus all the time spent irrigating by hand and maintaining solenoid valves and sprinklers as well as the indirect costs; managing water flow without the pump station being optimised, the lower yield of fertilisers and plant protection products and poor growth after seeding, as well as the potential adverse impact on the club’s reputation over time. These were all factors that influenced the decision to invest in more remedial work on the current, inefficient system (which would deteriorate further over time) or completely replace it with modern technology and components by phasing installation over several years“.
The system design centres on Rain Bird’s IC™ V8 Nimbus II Central Control with MI software, Windows 10 functionality and mapping. On fairways, triple rows of Rain Bird 751 rotors provide easy, top-adjustable full and part-circle operation, using much less hardware compared to satellite and decoders. Rain Bird’s latest 500/550 rotors are being installed on tees for precision watering.
Club Director, Giovanni Malcotti comments:
“Since the course was built in 1986, our irrigation system has served us very well and in all that time we’ve only made one significant improvement in adding the double rank system. However, after 30 years the plant is showing signs of structural weakness which means turning the system off for repairs which is not effective and also affects the quality of the turf. For Castelconturbia which needs to maintain its highest standards, the quality golf experience is being put at risk by plant obsolescence. The second negative aspect which affected our motivation for investing in Rain Bird’s latest technology was economic. Stopping the system for maintenance means extra working hours and spare parts which weigh heavily on the club’s overall budget and continually disrupt planned schedules for staff working on the course. Having evaluated the options and having shared these with our club committees, we chose to use Rain Bird for its system technology and for its great expertise in the golf sector.”
Rain Bird Golf has introduced two IC CONNECT™ products designed to make its industry-leading IC System even more functional and convenient for superintendents and their courses. The Rain Bird® IC-IN Integrated Control Sensor Input Device makes it possible to monitor and respond to on-site sensor information in real-time, using the IC System’s MAXI™ wire path. The Rain Bird® IC-OUT Integrated Control Output Device enables activation of remotely located equipment from the Central Control.
“Since 2009, the IC System has delivered total control and unmatched diagnostics to golf courses in over 40 countries around the world,” said Scott Rottler, Senior Product Manager for Rain Bird Golf’s Central Control systems. “As complementary devices, both the IC-IN and IC-OUT take the IC System to the next level by providing superintendents with additional functionality that can reduce water use, save time and reduce labour costs.”
Both the IC-IN and IC-OUT connect directly to the same IC System wire path as the Integrated Control Modules (IC Modules) used to activate sprinklers. Multiple IC-IN, IC-OUT and IC Modules may be connected to a single wire path, providing flexibility for the varied site conditions found across every golf course.
IC-IN collects and transmits data to the Central Control from sensor devices of various types, including flow, rain, pressure, temperature, wind speed, on/off and reservoir level sensors.
IC-OUT integrates the Rain Bird Central Control with remotely located products such as pumps, fans, gates, fountains, lights, motorised valves, DC latching solenoids and more. Users can now control these products automatically from the Central Control computer or manually via the Rain Bird Mobile Interface (MI Series™) application.
IC System customers can experience optimum control by using these IC CONNECT system components in combination with each other and Rain Bird’s Central Control system. Constant communication between the Central Control and the IC-IN and IC-OUT devices facilitates real-time, automated responses to changing site conditions. Thus, course management is simplified allowing superintendents and their staff to remotely manage irrigation and a multitude of other products that enhance the player experience.
“By providing simplified installation pinpoint diagnostics and easy expandability, the IC System has permanently changed the way golf course superintendents manage their irrigation systems,” Rottler said. “Now, with the addition of the IC CONNECT devices, the IC System continues to evolve, allowing superintendents to further fine-tune their watering and increase automation around the course.”
