Ridding Bees From Irrigation Valve Boxes

Bees building their hives in irrigation boxes is a somewhat common occurrence many places around the world.  They like the cool, dry, safe nature inside the box. Unfortunately, this can be dangerous for staff when they forget to check before opening. Always check the valve box by tapping the top first to insure the box is not inhabited prior to opening. Bees can be dangerous to golfers and others nearby as well when they begin to swarm. In some areas such as Florida and the coastal plains of Georgia, Alabama, Mississippi, and Louisiana some bees have become Africanized making them more aggressive and dangerous. Africanized honey bee colonies produce 4 to 8 swarms per year compared to the 1 or occasionally 2 produced by European colonies.

Ridding Bees From Irrigation Valve BoxesSo how do we get rid of them?

There are many different types of products available to eradicate a bee’s nest colony.  However, live bee removal and relocation helps the environment. A bee keeper will remove an established colony and relocate the colony to a suitable location, by carefully removing the hive by hand, and thoroughly cleaning the area to ensure that no honey residue or hive structure is left behind. He will then relocate the bees to give them a place to live where they can thrive. By doing so not only will the bees not return to the same location, the colony is preserved and the bees are able to continue their work.

Preventing them from finding your irrigation valve box as an attractive new home is the best Ridding Bees From Irrigation Valve Boxesmethod.   Prohibiting access to the irrigation boxes by filling the lock hole where they enter and exit with expandable foam sealant such as GREAT STUFF ™ Insulating Foam Sealant can help. Seal all the boxes and make sure your irrigation technician keeps a can handy so it can be replaced each time the box is opened. A small amount will fill the hole and force the bees to find a home elsewhere.Ridding Bees From Irrigation Valve Boxes

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.

ATI provided the irrigation system design, construction layout and inspection, as-built developmentATI provided the irrigation system design, construction layout and inspection, as-built development and central computer programming with the keen help of Derek Grenkowski and Protcion.

The system layout was performed using the survey method in coordination with Protcion.   Oleg Pyzyak with Protcion was instrumental in providing timely and highly accurate surveys of the grass lines laid out by Dirk Bouts of Nicklaus Design. The sprinkler design was then re-designed by ATI in the computer. The sprinkler locations were then laid out by Oleg using the same survey method.  This method based on the actually grass lines and features allows the designer to analyze several sprinkler layout options before selecting the optimum layout.  Learn more about the benefits and procedures involved with the survey Staking by reading the Survey Method Staking Blog dated July 27, 2015.

ATI is very proud to have been part of the team at Raevo Golf Club.

Survey Method Staking

Aqua Turf International utilizes a new and improved sprinkler system layout method that insures the best and most efficient sprinkler layout done that can be accomplished in an expeditious manner by making optimal use of the personnel and equipment already available on site . The process has been very successfully implemented on projects in the US, Bulgaria, Bahamas, China, Brazil, Egypt, Morocco, Russia and around the world.

Simply stated, the process is as follows:

  1. After shaping is approval and grass lines have been marked by the architect, the Contractor will coordinate the surveying of all the features necessary for the process such as the grass lines and perimeter of the greens , tees, bunkers, water features and cart paths. The dwg file is then provided to ATI either while on site or via email depending on the site schedule and services contracted.
  2. ATI will then re-layout the sprinkler and satellite locations in the computer and return the “As-Staked” drawing to the Contractor. The “As-Staked” drawing then becomes the foundation for the “as-built” drawing. At the same time ATI also prepares a sprinkler tracking sheet showing any add and deducts in the sprinkler quantity of each hole. This number is mostly influenced by the actual grass lines, shapes and locations of features. Some holes tend to get a little bigger and some a little smaller based on the architects important field changes to the golf course design.
  3. Prior to an ATI visit, the contractor will layout the   “As-Staked” drawing and stake the locations of the sprinklers and satellites from our “As-Staked” drawing. Our site visits should be scheduled if possible to coincide with this process. If the project is on a fast track this method allows the Contractor to continue if needed without a site visit if time is of the essence. Once the site personnel are experienced in the process it is very easily implemented.Survey Method Staking
  4. During the site visit ATI will check the staking and make field adjustments as necessary. Adjustments are typically minimal leaving more time for the important tasks of inspection and plan interpretation.
  5. After the staking is finalized, any changes should then be re-surveyed. The stakes can remain until installation or pulled and resurveyed later if they are in the way and installation may not happen soon.
  6. As soon as possible after the site visit ATI will email the updated “As-Staked” drawing to include station numbering and ID’s. If a decoder system is used this allows for prompt programming of the computer which is critical. Additionally a Sprinkler Tracking Spreadsheet is supplied to account for any differences between the design and as-staked quantities.

Survey Method Staking is a more productive and efficient method when compared to the traditional tape method. Survey Method Staking allows ATI to totally redesign the system by using the computer which allows us to more efficiently layout the sprinklers than with tapes. Using the computer can allow for several variations to be tried until the best sprinkler layout is determined. This is not realistic to expect with tapes in the field. The method is especially beneficial on hard-line type systems since the triangular grid can be rotated in the computer to best align along the longest straight grass line. In this fashion fewer sprinklers are required since the most sprinklers are along the grass line requiring less backup part circle sprinklers. This would be impossible to do as efficiently with tapes in the field.

As-Built Drawing and Programming then follow.

 Survey Method Staking produces the best possible sprinkler layout because:

  • The view from above the hole in AutoCAD takes the guess work out of staking.
  • We can set the baseline and rotate the triangular grid as needed to fit any hard-line edges reducing the amount of backup sprinklers on a hard-line system. This results in the fewest number and most beneficial placement of sprinklers.
  • Eliminates the inherent distortion and human error of dragging tapes or ropes across fairways and over mounds sometimes in high wind.
  • Often the construction is incomplete when layout is needed such as drainage so portions of the hole cannot be accessed with tapes.
  • Much less weather dependent.
  • The contractor immediately has an accurate as-staked plan to work from and the grass lines supplied by the architect in the field are immediately archived.
  • A solid foundation is laid for the construction record drawing.
  • Flags that get knocked out during drainage installation or from shaping adjustments can easily be surveyed back in the original location.
  • More flexible in regards to the schedule and site visits since holes can be done individually if needed. Also, if design changes are made after staking, a new layout can be done easily by repeating this process for just that hole.
  • No need to stake holes far in advance of installation since the process can be done remotely if needed. However, ideally Survey Method Staking is done in conjunction with ATI site visits.
  • Time during visits can be better spent on inspection and plan interpretation than pulling tapes!

Getting everyone off to a good start with and understanding of the process is helpful. For Survey Method Staking to work best it is essential that all features including greens well, bunker edges, tee tops, water features, cart paths and grass lines are surveyed new and nothing from the architects original design copied or referenced in. It is also important that the accurate inside edge of the cart path be properly identified. Sprinklers along the cart paths should always be installed last in any regard to insure they are properly aligned along the edge of the path as the final cart path edges are nearly impossible to define prior to their construction.

There may come a time when only one or two holes are ready to stake and the time and cost doesn’t justify a site visit from ATI. In this case, the same procedure will work; ATI just might not get a chance to field approve prior to installation. However, by that time in the project a good working relationship with the Irrigation Supervisor and Site Coordinator should be formed and all parties can work together to make any minor field adjustments.

The number of ATI site visits can be tailored to the needs of the project. ATI visits should include a pre-construction meeting and the final walk through. At a minimum four visits for inspection should be allotted.   Of course additional trips can be made as approved. Each staking trip will include inspection of the work performed a site report and an update of the sprinkler tracking spreadsheet. Also, the contractor should provide the as-built field notes of each hole with the station numbers and pipe routings as soon as the irrigation on the hole is completed so ATI can prepare the final construction record drawing (As-Built) drawing. This allows for timely programming of the irrigation computer which can be beneficial for a speedy grow-in. This is especially important for decoder systems that are 100% reliant on the central computer to operate.

Please note that various flag colors are required to represent different irrigation components. This will prevent rouge flags being installed as sprinklers. There are many flags on a construction site and the irrigation flags should be unique, easily identifiable and a separate color used for each model and nozzle size. The grass lines should be painted in a distinctive color paint or a different color flag than used for irrigation flags.

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 ( 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.
