Training and Mentoring

The New Zealand Water and Training Academy (NZWETA) will be delivering a new two day training course on Water Supply Modelling. This introductory course will cover modelling theory and application of modelling techniques for water reticulation. The training will not be in the use of any particular software package, but will enable participants to use any software application that models these phenomena. See the attached brochure for more info and for details on how to register.
