Sentosa Golf Club Tanjong Course Commences Construction

Sentosa Golf Club, designed by Andy Johnston and Swanson Golf Design, has recently commenced a total renovation of the Tanjong Course. The Serapong Course at Sentosa Golf Club had previously been renovated in 2006 and underwent an irrigation upgrade in 2015. The Serapong Course is renowned for hosting the Singapore Open on the European Tour as well as the HSBC Women’s’ Open on the LPGA tour. We all remember Paula Creamers’ dramatic 75’ winning eagle putt there in 2014. We are sure the Tanjong will provide an equally exciting and interesting but different challenge to that of the Serapong.

The project is on a fast track with re-opening scheduled for November 1st. Work has commenced on the driving range which also will function as the turf nursery for the rest of the fairways and roughs. The installation is on a fast track since the driving range must be completed and opened for the Singapore Open the week of January 28th!! The temporary water supply for the driving range grow-in will come from an interconnection to the Serapong irrigation system until the new pump station and mainline can be installed.

The golf course is being constructed by TEHC International PTE Ltd. and the irrigation system installed by Advanced Tech Irrigation Golf PTE Ltd., both from Singapore. ATI and TEHC were both involved in the Serapong irrigation renovations last year.

ATI provided the irrigation system design and is currently providing the system layout, inspection, as-built development and central computer programming with the keen help of Andy Johnston, GM at Sentosa, Rodney Mckeown GC Superintendent and CK Tan from TEHC International. The system includes wall to wall sprinkler coverage at 22m triangular spacing with individual sprinkler control to insure the utmost in water management.

The system features a Toro Lynx central control system with VPe satellites featuring with individual control of each Toro Infinity sprinkler. The system utilizes PVC mainline and fairway laterals and HDPE pipe for the green loops. The 511m3 per hour pump station is manufactured by Flowtronex. All the mainline and lateral valves are manufactured by Leemco.

TEHC has prepared installation samples of all the valve assemblies to be installed on the project. The samples were very beneficial for ATI inspection prior to installation, employee training and to help insure their material procurement is correct.

The system layout is being performed by ATI in coordination with TEHC International via the ATI survey method. TEHC is using their new Trimble G10 centimeter grade GPS mapping instrument. TEHC is instrumental in providing timely and highly accurate surveys of the grass and tree lines, course features and other important base information required to redesign the sprinkler layout based on the actual field conditions. ATI then re-designs the sprinkler layout in the computer. The new sprinkler layout is then laid out by TEHC using the same survey equipment.  Any revisions made during the inspection of the layout can be immediately surveyed and updated using the Trimble G10.   This method allows ATI to analyze several sprinkler layout options before selecting the optimum layout. This capability typically results in less sprinklers required to cover the same area because the triangular sprinkler grid can be finely aligned to the turf perimeters. Not only does this process improve the quality of the layout it helps provide an immediate real-time accurate as-built record of the installation. Additionally the stakes at each irrigation sprinkler are no longer required getting in the way of other trades such as grading and drainage installations prior to the irrigation installation.

Raevo Golf Club Nearing Completion

Raevo Golf Club, a Jack Nicklaus Signature Design just outside of Moscow is quickly nearing completion. Grass was planted on the final two holes last week and only completion of a small chipping area remains.  James Schumacher, President of ATI was on site July 9 – 15 to inspect the irrigation installation on the final 6 holes. Also, a final irrigation punch list for the other 12 holes and practice area that have already been grown-in was preformed. The irrigation system design utilizes a hard-line style with part circle sprinklers along the turf perimeters of each rough A hard-line sprinkler layout style saves water, reduces weeds and excessive growth of the native grass.   The golf course was constructed and irrigation system installed by Protcion from Moscow.

The system features a Toro Lynx GDC off – fairway decoder control system with individual control of each sprinkler. The system utilizes AquaFuse HDPE pipe with the materials and on-site HDPE training provided by CMF Global.  The 465m3 per hour pump station is manufactured by Watertronics. The pump station is uniquely hidden From sight and play in a building surrounded and covered by mounding.  Even though the pump station slab is at fairway level the pump station is hidden from view from virtually every angle.

Better Water Systems

In the coming years, many factors will influence golf course irrigation design, construction and operation. Irrigation consultant Michael J. Krones, Ph. D, outlines what the industry can expect to see over the next decade and beyond.

Advances in technology and agronomy will continue to result in changes in golf course irrigation design, construction, and operation. Irrigation water availability and climate change are the most critical driving factors behind these changes. The public’s interest in golf and its expectations for the appearance and playability of the course will also continue to have impacts on irrigation design.

Technological and agronomic advances will be adopted based on the function of golf course irrigation: promotion of a healthy and robust turf, accurate use of water, minimization of wasted water, optimization of energy consumption, and optimization of labor costs. In pursuit of these goals we will see better sprinklers, better sensors, and better control systems.

New turf cultivars combined with what architects and the public desire (and perhaps, can tolerate) may result in some changes in the amount and nature of the water used for irrigation. It may be possible to have successful golf courses located in areas that are now impractical from a climate perspective or where currently acceptable water volumes and quality prohibit such endeavors. These possibilities don’t necessarily influence the irrigation system – it’s likely that all of the turf will need some level of irrigation, either as the sole source of plant moisture or as a supplement to natural water. But such changes may result in less irrigated landscape and perhaps necessitate more accurate application of the water. That may mean more sprinklers per unit area of turf with more specific control features.

Technological advances are likely to be the most obvious and useful changes. While it is unlikely that we’ll see an alternative to the pop-up sprinkler as a means of applying the water, we can expect improvements resulting from materials and methods of sprinkler construction and system (or supervisory) control and data acquisition technology.

Sprinkler manufacturers will continue to improve sprinkler performance by introduction of new materials and flow paths for use in the nozzles and rotational drives. The science and practical application of frictionless coatings is advancing rapidly. Perhaps that technology will become cost effective for the sprinkler and valve manufacturers. The result will be better distribution uniformity and lower head loss which will result in some modest water and energy conservation.

We are all familiar with communication and control system advances simply because we all use computers, phones, tablets, and other interconnected devices. Therefore it makes sense to have great expectations for advances in irrigation control technology. Accurate use of water with minimal waste requires environmental and system sensing feeding into control algorithms that regulate water application and operation of the irrigation system. A dense, distributed array of sensors, perhaps a mesh network, that includes soil moisture and temperature sensors and system pressure and flow sensors can help apply the required water where it is needed, minimize the loss of water through over-irrigation, evaporation, wind drift, and leaks, and minimize pumping energy. Imagine regulating pump power not just as a function of the pressure at the discharge from the pump station but of the pressure at the sprinkler.

Royal Calcutta Golf Club System Analysis

James Schumacher, President of Aqua Turf International, Inc. (ATI) recently visited Royal Calcutta Golf Club in Kolkata, India to perform a System Analysis and prepare a Long Range Improvement plan. Founded in 1829, Royal Calcutta Golf Club (RCGC), affectionately known as the “Royal”, is the oldest golf club outside the British Isles, the oldest being the Royal and Ancient, St. Andrews in Scotland, the home of golf. Originally located near the Calcutta airport, the club moved to its present location at Tollygunge in 1910. The Royal’s conspicuous features are its strategically located water tanks natural water hazards and beautifully tree lined fairways. The club has approximately 2,000 Members, 1,100 of those are golfers of which 700 are considered active players.

The irrigation system is antiquated and has become a limiting factor to the turf maintenance program. The golf course operations are managed by Quality Turf international of Bangkok, Thailand (http://www.qualitygolfasia.com/) who was instrumental in leading the club to hire an independent analysis of the status of the irrigation system. ATI has been contracted to evaluate the system and make recommendations for improvements.

During the site analysis, the entire system was inspected and the following criteria evaluated:

  • Water Sources Water Quality and Availability
  • Water Storage and Irrigation Requirements
  • Pump Station
  • Pipe, Fittings and Valves
  • Sprinklers and Coverage
  • Control System and Wiring
  • Desired Standards of Operation
  • Original Installation
  • Maintenance Procedures and History
  • System Performance, Reliability and Limitations
  • Turf Needs and Soil Conditions

While on site Mr. Schumacher was assisted by Mr. Tim Denham, Golf Course Superintendent, along with Mr. Nikhil Sanwal, Assistant to the Golf Course Superintendent.

Royal Calcutta Golf Club is anxious to host prestigious tournaments in the near future. Bringing the irrigation system up to standard with the help of ATI and Quality Golf International will be very helpful in achieving that lofty goal.
