Aquatech Consulting is a small firm of consulting engineers based in Narrabri NSW. Aquatech Consulting specialises in the investigation, design and construction supervision of water resources and irrigation projects and the assessment and improvement of irrigation water use efficiency. Aquatech provides consulting services directly to their own clients and also provides specialised irrigation engineering back-up to 18 other independent consultants throughout eastern Australia for the measurement and improvement of irrigation water use efficiency. While based in the north-western New South Wales and south-western Queensland Irrigation Areas, Aquatech undertakes projects throughout Australia and overseas.

Typical projects undertaken by the firm have included:

  • Measurement and evaluation of irrigation system performance (surface, sprinkler and drip) using the Irrimateä service
  • Provision of whole farm water balance and water management services using WaterTrackä. Feasibility studies for irrigation development potential
  • Design of specialised water control and measurement structures
  •  Repair and re-development of existing irrigation systems
  • Whole farm planning of water conservation and irrigation development for properties ranging from a few hundred hectares to several thousand hectares. Work includes location and investigation of storage sites, pump sites, irrigation areas, most suitable form of irrigation, etc.
  • Complete farm irrigation system design and construction supervision (pumps, channels, field levelling, tailwater return, etc.) for areas ranging from less than 100 hectares up to several thousand hectares
  • Evaluation of existing Group irrigation schemes, for both public and private sector clients, including rationalisation of delivery and drainage systems
