 Product Description


Olympic 2-WS

For increased stream leangth the Olympic 2-WS relys on the T165XP Expansion Reservoir. Designed for the open landscape, this kit will support a 4 ft wide stream running 110 ft with enough liner for an impressive 25 ft total of vertical waterfall drops.

For complete system information, design specifics and installation advantages please visit:


Stream Size:

4 feet wide x 110 feet long


Vertical Drop:

Up to 25 feet


What is Vertical Drop?

Vertical Drop is the combined height of the system's waterfalls. For example if the system has four two foot waterfalls the total vertical drop would be 8 feet.


Design Notes:

  • The length of liner included with each kit is longer than the stream to account for vertical drop and turns in the stream channel.
  • The stream width of 4 feet mentioned above is the width of the stream channel before adding rock.
  • The gravel depth over the liner is based on 1-1/2 inch of gravel over the bottom of the liner.
  • The depth of water over the gravel will be approximately 3/4 of an inch.
  • A valve to adjust water flow is included with each kit.
