Water Treatment Design

Services include:

  • Drinking water compliance reports
  • Iron and manganese removal
  • Taste and odour removal
  • Potable water process design

These are just two of our current Water Treatment Design projects

Kaikoura Water Treatment Upgrades - Concept design for a treatment plant to remove iron and manganese from groundwater. (Current 2008)

Waitakaruru WTP Filters Automation Conversion - Investigations and design of new valve configurations to complete the conversion of the existing (Candy) filters to automated backwash. Design and specification of replacement media and reviews of supplier proposals. (Current 2008)

Fonterra,  Kauri,  WTP  Optimisation  Trials - On-site trials  to identify upgrades to the plant to improve operating efficiency and determine feasibility of dealing with taste and odour problems by adoption of an enhanced coagulation regime.

Waitakaruru  WTP Coagulation  Upgrades - Coagulation trials to identify low-impact improvements to the coagulation regime to overcome problems of sludge treatability, filter blinding and compliance.

Waipa District WTPs Optimisation Trials - On-site trials which identified a programme of relatively minor works to provide substantial improvments to treated water quality at Te Tahi, Parallel Road and Karapiro WTPs.

Kihikihi Water Quality Improvements - Directed study to identify works required to address problems due to high iron and manganese in the Kihikihi reticulation.

Te Tahi WTP Upgrade Strategy - Identified and scoped works to upgrade capacity of Te Tahi WTP to meet predicted future demand in the context of expected reductions in source availability with the renewal of water take permits.

Maungaturoto WTP Optimisation - Identified improvments required to raw water handling and upgrades to flocculation process to enable treated water quality to comply with Drinking Water Standards.  Identified potential for a significant gain in throughput without need for a major capital works programme.
