Drainage Systems


A dry well is an underground structure that disposes of unwanted water, most commonly storm water runoff, by dissipating it into the ground. Simple dry wells consist of a pit filled with gravel, riprap, rubble, or other debris. Such pits resist collapse. These dry wells are usually buried completely, so that they do not take up any land area.

Submersible Pumps

Submersible pumps are found in many applications:

  • Single stage pumps for drainage
  • Sewage pumping
  • General industrial pumping
  • Slurry pumping
  • Aquarium filters

Multiple stage submersible pumps are typically lowered down a borehole and used for water abstraction or in water wells.

French Drain

A French drain, or land drain, is a ditch filled with gravel. It redirects surface and ground water away from an entry point and toward a sump pump. French drains are common drainage systems, primarily used to prevent ground and surface water from penetrating or damaging building foundations. Alternatively, the French drain technique may be used to distribute water, such as that which flows from the outlet of a typical septic tank sewage treatment system. French drains are also used behind retaining walls to relieve ground water pressure.
