Modelling of the following

  1. Ground water flow
  2. Ground water contaminate transport
  3. Ground water contaminated site
  4. Water networks
  5. Potable water quality
  6. Reservoir optimisation
  7. Water pumping optimisation

 

Reticulation modelling is:

  • Predicting flows and pressures in a water network
  • Optimising levels of service
  • Predicting effects on water quality throughout the network
  • Biofilm control
 

Groundwater modelling is a powerful tool for:

  • Studying the effects of proposed groundwater takes such as irrigation supply
  • Predicting the effects of ground water mounding
  • Studying water quality effects from waste water disposal or soakage and contaminated sites

Our past projects include:

Ruakaka Wastewater Disposal Impact Assessment - Developed numerical model (Visual MODFLOW) to assess the effect of discharge of wastewater to the coastal dune system on the stability of the beach and sustainability of the foredune. Designed and executed field investigations of soil hydraulic properties.

Maketu High-Rate Irrigation Model Study -developed models of groundwater flows (Visual MODFLOW-SURFACT; FEFLOW) and phosphorous sorption (VS2DT) associated with a proposed land disposal system for discharge to ground of treated wastewater.  Estimated capacity for P removal and indirect discharges to the surface environment.
