This can be installed in an excavated trench. Specialised mole ploughs are available that can form the hole, insert the perforated pipe (and gravel if required), all in one simultaneous and continuous process. An extremely powerful (usually tracked) tractor is necessary. The flexible pipe is carried as a roll on the back of the machine.
The connection of geonets to perforated drainage pipes is difficult and extremely important. The geonet's outlet must be free draining at all times even in winter under freezing conditions. Notwithstanding the above concerns, geonets are very impressive with respect to their flow-rate capability, ease of construction, savings in airspace, and ...
A diagram of a traditional French drain. A French drain [1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain [1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area.
Attaching the drainage pipes to the suspended form; Filling the trench with concrete (surrounding the form base and sides) and finishing the concrete flush with the metal frame; And after drying, removing the wooden form, cleaning the pipe inverts and placing the grates in the frame. This installation method is by far the most labor-intensive.
A septic drain field, a septic tank, and associated piping compose a septic system. The drain field typically consists of an arrangement of trenches containing perforated pipes and porous material (often gravel) covered by a layer of soil to prevent animals (and surface runoff) from reaching the wastewater distributed within those trenches.

The hard-type cover wouldn't go flush with the siding, which made me worry, but this one seals flush to the pipe, which I like. So far, so good." "They’ve lasted two winters and [are] still in ...
High-density polyethylene pipe installation in a storm drain project, Mexico. Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need ...
In plumbing, a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass through. In oil refineries, traps are used to prevent hydrocarbons and other dangerous gases and chemical fumes from escaping through drains.
