Underground field drainage

Underground field drainage improves field productivity

The transformation of open ditches into crop land through underground drainage increases the arable land area by 10-20%. At the same time, shaping, sowing and harvesting takes less time as machinery is able to work more efficiently. New drainage is typically needed when improving the drainage of old fields or changing field parcels. Field drainage plans include the surface shape, soil quality, ground water conditions, possible discharge locations and the locations of drainage water collection and drainage pipes and their service drains.

Uponor field drainage pipes are flexible, corrugated PVC pipes that are mainly used for the drainage of fields and green areas. In addition to ordinary perforated coiled and standing pipes, the selection includes unperforated installation pipes coated with coconut filters. Uponor field drainage pipes comply with the quality and functional requirements of standard SFS 5211 and have been granted the SFS marking. The selection also includes drum and combination pipes for field and road ditches.

In addition to the pipes, the field drainage system includes underground drainage chambers and outlets. Check fhe product catalogue for all the components of the system.

Drainage chambers
The field drainage inspection chambers are easy to install thanks to a few small, yet important, details. The drainage chambers are light and equipped with lifting loops, which makes them easier to handle at the installation site. Because the chambers do not have fittings, they can be installed to the desired height. Chambers can be installed 0.5 m below the ground, in which case the metal flap on the lid indicates its location. The base of the chamber is easily anchored in place.
Outlets
The orange colour of the discharge plug stands out well from the terrain, making it easier to locate on inspection and maintenance visits. The metal flap on the outlet prevents moles and other small burrowing animals from getting into the drainage network and causing blockages. The metal valves are long enough to ensure that the pipe is anchored securely in the ground.
