Installation schematics for Lakes and Lagoons
The following page explains how to install an aeration system in a lake or a lagoon
Installation procedures click here
Type 1 lake, round shallow with no deep sections
Type 2 lake. a large surface area, shallow ( 1 to 4m) with no deep holes
Type 3 lake, a large surface area with a deep section in which all diffusers are located
Type 3 lake, a quarry type configuration, lake is deep with steep sides or a deep water dam at one end
Type 4 lake, similar depth through-out the lake, but reasonably deep at edges,
mdpe pipe goes around the perimeter of the lake and diffusers come of the pipe via hose connections

For the installation type below, the air delivery pipe is submerged below the water, and anchored to the base with weights. The water depth is 4m, so 5m of hose is connected between the air pipe and the diffuser. This arrangement means that you can hook the air diffuser hose and recover the diffusers for occasional cleaning. The diffusers used should be code 6.2.10, 3m long diffusers 10 cubm/hr air flow fitted with non return valves.
