DRAINAGE DESIGN AND
Water table lowering / stabilisation
Agricultural and sports drainage
Drainage is generally seen as the opposite of irrigation but they are better seen as two components of the same cycle.
Hydreau Ltd sources and collects water for irrigation use, and identifies, combines and directs water for drainage requirements.
Civils drainage systems are generally gravity systems, with an element of attenuation or hydro-braking normally to greenfield runoff rates.
Land/field drainage for crops generally involve water-table lowering, and sports pitch and golf drainage involves taking water off a surface as quickly as possible, bypassing the soil-structure where permeability is low.
Hydreau Ltd designs all of these drainage systems.
