Sand Channel Drainage

System Design

Sand Channel Drainage designs and installs sub-surface drainage systems for sports fields and golf courses. Each system consists of a network of interconnected channels filled with a high performance drainage medium. The network is designed to collect surface water and carry it away. The company’s systems implement the concept of vertical bypass drainage. The combined effects of gravity, capillary action and adsorption move water into and through the network of channels, effectively bypassing the surrounding soil.

Every system uses two types of channels:

  • Sand channels are 1″ wide x 9″ deep. They are filled entirely with sand.
  • Pipe channels are also 1″ wide x 9″ deep. Hi-Flo pipe is installed at the bottom of the channel, and the remainder of the channel is filled with sand.

gridChannels form a grid:

  • Sand channels are typically aligned perpendicular to the primary direction of fall. The sand channels collect the bulk of the water and provide pathways for the water to move laterally to intersecting pipe channels. In a high-intensity system, where sand channels are spaced at 16″ intervals, water is never more than 8 inches from a sand channel.
  • Pipe channels are installed at right angles to the sand channels; typically they are parallel to the primary direction of fall. When water reaches a pipe channel, it seeps through the narrow slits in the Hi-Flo pipe and is carried away.

Grids come in two configurations:

  • High-intensity systems are configured with sand channels on 16″ centers, and pipe channels on 48″ centers. High intensity systems are designed for heavily trafficked areas such as sports fields and putting greens.
  • Standard systems are configured with sand channels on 24″ centers and pipe channels on 48″ centers. Standard systems are used in less-heavily trafficked areas such as play fields and golf course fairways.

Collector lines consolidate pipe channel output:

  • Collector lines are installed at the low end(s) of the pipe channels. They consolidate the output of the pipe channels, and carry it to the point of final disposal.
  • The size of the collector lines is based on the amount of water they are expected to handle. Typical collector lines are 2″-4″ in diameter.

Many opportunities to use Sand Channel drainage:

  • Whenever drainage is an issue, Sand Channel drainage is an option.
  • Sand Channel drainage is appropriate for all types of projects –
    • Initial construction
    • Comprehensive renovation
    • Stand-alone improvement

Minimal maintenance requirements:

  • Sand Channel systems need minimal maintenance. We recommend that overlying turf areas be aerated and top-dressed at least twice a year. This improves the lateral movement of surface water, and enhances the interface between the playing surface and the subsurface drainage system.
