Capability
Mine Site Dewatering & Drainage Contractor in Western Australia
Core Civil Mining delivers comprehensive mine site dewatering and drainage solutions across Western Australia's operating mines and civil construction projects. Effective water management is fundamental to maintaining site productivity, protecting personnel safety, and preserving the integrity of earthworks structures. Our experienced teams design, install, and operate pit dewatering systems, open drains, culverts, sedimentation basins, and stormwater diversion channels tailored to each site's hydrology, topography, and regulatory obligations under the WA Department of Water and Environmental Regulation (DWER).
We manage the full spectrum of groundwater and surface water management on mine sites — from initial bore field development and spearpoint installation through to high-volume pump-out programs, reticulation pipework, and discharge to approved disposal points. Our dewatering superintendents work closely with principal contractors, geotechnical engineers, and hydrogeologists to ensure every system performs reliably through seasonal wet periods and the extreme rainfall events common in WA's north-west Pilbara and Kimberley regions.
Our drainage construction capability includes engineered cut drains, lined and unlined channels, rock-armoured spillways, culvert installation, hydro-seeding of disturbed batters, and stormwater detention pond construction. We construct all drainage infrastructure in accordance with relevant geotechnical and hydrological designs, with ongoing monitoring and maintenance programs available throughout the mine's operational life. Our teams are experienced in sedimentation pond construction and management, protecting receiving waterways from silt-laden discharge during earthworks programs and wet season operations — a critical compliance obligation under WA environmental licensing conditions.
Core Civil Mining's integrated HSEQ management system governs all mine dewatering and drainage activities, with real-time reporting of pump output, water levels, and discharge quality maintained throughout operations. We hold all relevant water abstraction and discharge licences and maintain close communication with site environmental teams to ensure compliance with DWER licence conditions, DMIRS requirements, and project-specific environmental management plans. Whether you need a standalone dewatering campaign for a pit push or a full wet season water management program across an operating mine, Core Civil Mining has the expertise and equipment to keep your site dry, safe, and productive.
