THIS ARTICLE IS A CASE STUDY OF HISTORICAL PROJECTS HYDROSOLUTIONS HAVE WORKED ON.
BHP BILLITON IRON ORE PTY
Redmont Railcamp Potable Water Source Protection Plan, Pilbara, Western Australia
A source protection plan was developed for the potable water abstraction bores supplying Redmont
railcamp, consistent with Department of Water and Water Corporation guidelines.
Raw water is obtained from two bores completed within a weathered pegmatite associated with the current
course of the Coonarie Creek.
A numerical groundwater model was constructed using FLOWPATH covering the groundwater and surface
water catchments supplying the aquifer.
Time of travel zones were defined including:
- 60day Source Protection Area (SPA) to provide a sanitary protection zone
- 365day SPA, equivalent to a wellhead protection area priority 2 area
- Total catchment area.
Incompatible landuses were identified and an initial risk assessment to the raw water source was undertaken.
Recommendations were made to undertake a review of the water treatment and distribution system
consistent with the Australian Drinking Water Guidelines 2004.
