Solves Drainage Problems For Less Than $150/ha

Client: GR&S Singh

Location: North Queensland, Australia

Notes: 52 hectare half Centre Pivot growing sugar cane on 1.5m furrows. Client wants better drainage to allow more timely machine operations/access and less compaction particularly during harvesting.

Cut Fill Map


The Cut/Fill map shows that although 80% of the field drains naturally, there are areas where significant ponding can occur. The aerial photographs (see this field in Google Maps) shows these areas are generally around a meandering natural drainage line. With minimal earthworks OptiSurface landforming corrected this problems and promoted the signficant benefits that come with optimal surface drainage.
