Wash Pad Demonstruction – Final Construction Activities

Construction on the wash pad prototype demonstration at Locust Hill Country Club is in the final construction stages (see the blog post describing the project and the blog post on mid-construction activities).

Below are photos showing the testing of the last component of the system, the booster pump, and construction of a level pad next to the existing wash pad for the equipment to be placed on. The booster pump will take water from the supply tank and pump it into the hoses used to clean equipment. As part of this process, the operating pressure and GPM were measured and determined to be within range engineered for the system.

Wash Pad Demonstration @ Locust Hill

Following the publication and launch of the NYS BMP website, an extensive survey of superintendents in the state was conducted to assess level of competency regarding BMPs and existing alignment of properties with established BMPs. The survey suggested priority areas for our education and outreach efforts, including maintenance facilities and organic- and chemical-waste management and containment. For example, the need for affordable equipment-washing solutions was obvious as well as observations during course visits in NY State.

To address this need, we have initiated a demonstration project on equipment wash pads in partnership with the Locust Hill Country Club in Rochester, Cornell University, the New York State Pollution Prevention Institute at the Rochester Institute of Technology (RIT), and the University of Buffalo. Prior to the demonstration, Superintendent Rick Slattery worked with RIT on a NYS Department of Environmental Conservation (NYSDEC)-funded feasibility study that collected baseline information for the design of a new wash pad system, as summarized in our case study.

Locus Hill Country Club is a perfect site for this demonstration project for two reasons: the commitment of Superintendent Slattery to environmental stewardship and a real-world issue that needs to be addressed. Slattery has been nationally recognized for his commitment and has been awarded the NYSDEC Environmental Leaders award. He has also shepherded Locust Hill through the Audubon International certification process to achieve Certified Cooperative Sanctuary status.

The real world issue addressed in the demonstration project is the volume of wash water generated by Locust Hill. Being located at the edge of the suburban-rural divide, houses surround the Locust Hill course. Proximity to the equipment wash pad drainage area resulted in adjacent homeowner’s complaints of odors from the discharge. Because functionally organic debris (clippings, leaves, etc.) was already strained from the wash water, addressing the amount of water being used in washing operations is the solution to eliminating odor issues

This demonstration project is utilizing the feasibility study results for the design of an affordable equipment wash pad system that is estimated to reduce water use by up to 90%. Funded by a Turf Environmental Stewardship Fund grant, a prototype wash pad system is being built and its performance will be documented.

While construction is under way, Locust Hill staff are already implementing two of the feasibility study recommendations: blowing off clippings before washing and using low-flow nozzles to significantly reduce water use. Construction of the new wash pad system should be complete by the end of this summer. A Cornell University case study, project report, and conference presentations will follow to provide detailed information useful to superintendents across the state.

The slide show below depicts the wash pad operations prior to the development of a prototype wash pad that will dramatically reduce water usage. We will provide a mid-construction update on this blog later this year.

Dollar Spot

Dollar spot, caused by the pathogen Sclerotinia homoeocarpa, is a common golf course disease in New York State. Besides using chemical controls, managers can plan to lessen disease incidence and severity with the following activities:

  • Plant resistant cultivars of creeping bentgrass such as Memorial and Declaration.
  • Minimize moisture stress and leaf wetness.
  • Remove morning dew as early as possible.
  • Roll putting greens three or more times per week.
  • Apply biological organisms known to suppress dollar spot such as Bacillus licheniformis, Bacillus subtilis, and Pseudomonas aureofaciens.
  • Use horticultural oils (Civitas), labeled for the intended use both for treated area and pest, instead of or in conjunction with traditional fungicides.

Seasonal Variations in Runoff Potential

Water enters hydrologic systems as precipitation, primarily in the form of rainfall or snowmelt. It is then delivered to surface waters from runoff or infiltrates into the subsurface. The amount of water that infiltrates into the ground versus becoming runoff depends on a number of variables, including the intensity of precipitation or irrigation, soil infiltration capacity, site characteristics, antecedent soil moisture, and season. The following are some of the seasonal changes in runoff versus infiltration potential:

During the winter, soils in New York are likely to be frozen and impermeable to water. Snowmelt, rain, and low evapotranspiration rates in the spring generate wet soil conditions and downward movement of water to groundwater. The potential for runoff is high because the near-saturated or partially frozen soils have low water infiltration capacities.

During the summer, high rates of evaporation and plant water uptake may reduce soil water storage, leaving none to percolate downward. Summer rains only partially recharge the soil profile, and the soil’s moisture holding capacity is typically not exceeded. Except for high-intensity thunderstorms, runoff and erosion potentials are generally low during the summer.

In the late fall, evapotranspiration rates decrease, and groundwater recharge occurs when the moisture-holding capacity of the soil is exceeded. Runoff and erosion potentials also increase during this period. However, in New York, runoff from turf most often occurs from wet soils and not from high rainfall intensity.
