Design
Infinity pools are very expensive and require extensive structural, mechanical (hydraulic engineering) and architectural detailing. Since they are almost always built in precarious locations (cliffs, mountain tops, beach front, etc.), sound structural engineering is paramount. The structural engineering must be based upon the geological conditions found on the site. A geotechnical report is commissioned prior to the commencement of the structural engineering. The high costs of these pools is often found in the foundation systems that anchor them to the hillsides.
In reality the edge of the pool terminates at a weir that is 1/16 - 1/4" lower than the required pool water level. A trough or catch basin is constructed below the weir. The water spills into the catch basin, from where it is then pumped back into the pool.

Famous quotes containing the word design:
“Joe ... you remember I said you wouldn’t be cheated?... Nobody is really. Eventually all things work out. There’s a design in everything.”
