Examples of Curtain drain in a sentence

• Curtain drain designCurtain drain design (see preceding figures) is dependent on the size of the contributing drainage area, the amount of water that must be removed, the soil’s hydraulic properties, and the available slope of the site.The contributing drainage area is estimated by outlining the capture zone on a topographic map of the site.

• However, the following conditions are present at the site which have nullified the presence of the limiting layer: Check all that apply Curtain drain will be installed to address limiting layer.

• Curtain drain piping: Up-slope of the up-slope side and on the cross slope ends of the disposal field, where the excavation is filled with curtain drain stone, the pipe shall be perforated.

• Curtain drain extension piping: Down-slope of the down- slope side of the disposal field, and beyond the extent of the curtain drain stone, the pipe shall be non-perforated.
