About Groundwater development services
Groundwater Development Services (GDS) is an independent hydrogeology consultancy run by Trevor Haig.
Groundwater consulting services are provided to the West Australian mining and construction industries. GDS provide a broad spectrum of hydrogeology services from desk top studies to regional groundwater assessments. Hydrogeological support has focused on the exploration, assessment and development of groundwater supply. GDS also provide technical support for site water balances, ground dewatering assessment, bore field sustainability and regulatory reporting.

Project work is ongoing. GDS provides “as needed” hydrogeology support to the Collie coal operations.
Hydrogeological consulting services has focused on pit dewatering. Technical support has included: the tracking of dewatering in two operational pits, modelling of projected dewatering requirements for life of mine planning, design of future dewatering infrastructure, pit lake modelling for post mine closure and upgrade of the current monitoring program through the installation of VWP monitoring bores.

PoRT KEATS STUDY
The Port Keats Study is a review of the water resources in the Daly River and Port Keats and Malak-Malak Aboriginal Land trusts of the Northern Territory.
In the study, the groundwater and surface water studies were mapped, described and evaluated. The traditional knowledge of the Aboriginal people holds in regards to their water resources was incorporated into the technical study. The reporting also included the creation of two 1:250,000 scale groundwater and surface resource map of the area which summarise the conceptual hydrogeology and supply potential.
The study supported future aspirations of development and creation of “country” for the communities of Wadeye, Peppimenarti, Palumpa, Nauiyu and Woodycupaldiya. The fieldwork required both public and private consultation with the aboriginal people who held custodianship of country.
The works included the drilling and construction of numerous exploratory and assessment bores. In many cases, the bores were then passed on to the traditional owners to support local water supply requirements.

GDS have provided a variety of hydrogeological services to the Leonora Gold Project in Western Australia.
The water story began with a regional desktop study to identify groundwater supply potential. The baseline information led to a strategic groundwater development plan in the pre-feasibility study. GDS provided targeting for the water exploration program using available resource drill rigs. The exploration program led to two hydrogeology drilling campaigns to drill, construct and test production bores to meet mine development requirements. The hydrogeology consulting included numerical modelling with MODFLOW to estimate drawdown impacts from dewatering and water balance pit lake modelling for forward development planning.
The Tiwi Island Water Study
The Tiwi Island Water Study mapped, described and evaluated the water resources on the Tiwi Islands in the Northern Territory. The study was presented So individuals without a scientific could use the information to make informed decisions. Download The Report
The outputs were a set of decision-making tools which comprised reports, maps and an interactive CD-ROM containing monitoring data, maps and GIS. The study was presented in such a way that individuals without a scientific or technical background could use the information to make better decisions in regard to the management of their water resources. The information was compiled for the Tiwi people, their community leaders and the Tiwi Island Land Council.
The study area supported the development aspirations of the aboriginal people in the communities of Nguiu, Milikapiti and Pirlangimpi. The field work was completed on both Bathurst and Melville Islands and comprised community and individual consultation, geophysical surveys and the drilling and construction of numerous exploration, assessment and supply bores.
The study targeted the primary aquiver on the islands, which is the Van Diemen Sandstone. The outputs were reports and two regional 1:250,000 scale groundwater and surface water maps.

Pilbara Cost Water Study
The Pilbara Coast Water study is a regional groundwater study focusing on the Pilbara region of Western Australia.
The study is a source review of all groundwater, surface water and supplementary supply options in support of the regions coastal supply schemes. The study highlights the most potential groundwater supply options for development in the near future. The study extends from the Carnarvon Basin to the West Canning basin along the Pilbara coast. The study focuses on three main port facilities associated with Onslow, Dampier and Port Hedland. Potential groundwater supply options were identified, which include the Fortescue River alluvium, Harding River fractured bedrock, West Canning Basin, De Grey River Alluvium, Yule River alluvium and the Lower Robe River.
