She is skilled in numerical and analytical groundwater modelling. She completed her Masters in Civil Engineering in 2004 on groundwater-surface water interaction and she continues to conduct research in this area and provides advice to Council and other organisations.

Katy has 16 years of experience as a professional consultant proving technical solutions to groundwater issues in New Zealand, Australia and overseas. She has assisted a broad range of clients in the agriculture, construction and mining sectors, as well as various government bodies, with issues around water supply, dewatering, groundwater contamination and wastewater management. She specialises in hydrogeological conceptualisations, groundwater resource evaluation and environmental and aquifer impact assessments.

Katy has significant experience designing and managing groundwater supply projects from the initial desk-based assessment, through the field investigation, resource modelling and borefield design, to obtaining resource consent. She also regularly assists the contaminated land team with the hydrogeological aspects of their projects.

Neil is a hydrogeologist with 14 years of experience. His key skills are in regional and local scale groundwater modelling. Neil has also been involved in a wide range of consenting projects in New Zealand and specifically Christchurch, including presenting evidence at hearings. He is also involved with the technical review of consent applications on behalf of several regional councils. 

Neil’s role at PDP involves working on a wide range of groundwater management issues including assessments of groundwater quality and quantity within Canterbury, and elsewhere in New Zealand. These include the effects of land use and activities on groundwater and the interaction between groundwater and surface waterways. Neil has extensive experience with groundwater models including detailed uncertainty analysis, gained both in New Zealand and in the UK. 

Parviz is a hydrogeologist, specialising in groundwater assessment. He has over 15 years of experience relating to the assessment of groundwater resources, hydrogeological assessments and groundwater flow and contaminant transport modelling. He has also been involved in the preparation of AEE documents for various consent applications related to groundwater resource and environmental effects assessment.

Additionally, Parviz has developed numerous groundwater models throughout the greater Auckland area, including a comprehensive groundwater model for the whole Auckland Isthmus as part of the Global Aquifer Study (GAS) and has won the modelling award for the best paper at the Water NZ Conference in 2010.

Peter is one of PDP’s Christchurch-based directors, with over 25 years of experience in environmental assessment and management, with a focus on groundwater and contamination issues. He was the lead author of nationally utilised guideline documents dealing with the effects of groundwater pumping on surface water bodies and the management and monitoring of seawater intrusion on groundwater in coastal aquifers.

Possessing significant experience as an expert witness, Peter has provided technical evidence related to groundwater effects in hearings for the consenting of landfills, hydroelectric power schemes, and community irrigation schemes. He is also involved in hearings and debates regarding groundwater allocation and water management issues and planning requirements to protect both surface water and groundwater quality.

As a certified Independent Hearing Commissioner Peter has fulfilled that role for regional council hearing panels dealing with resource consent applications for water abstraction and wastewater discharge activities.

Ramon is a Chartered Professional Engineer with 30 years of experience in civil engineering, primarily in the areas of river engineering/flood management and geotechnical engineering.
