Dewatering & Water Management
Groundwater control that keeps deep excavations dry, safe and on-program.
Water under control.
C&S Drainage Contractors provides the dewatering and water management that makes construction possible in challenging water conditions — high groundwater, seasonal flooding or complex drainage requirements — across metropolitan and regional Western Australia.
Our crews manage deep foundation excavations, pre and post weather-event water control and systematic site-wide water management for major infrastructure projects, using advanced pumping systems, strategic water collection and environmentally compliant disposal. The result: safe working conditions in excavations, surrounding infrastructure protected from water damage, and stable ground throughout construction.
What the scope covers.
Deep excavations
Dewatering for deep foundation excavations and below-grade construction — maintaining safe working conditions while protecting surrounding infrastructure and ground stability.
Weather events
Pre and post weather-event water control for sites exposed to seasonal flooding, keeping programs moving before and after the rain hits.
Systems & disposal
Advanced pumping systems and strategic water collection methods paired with environmentally compliant disposal techniques and full environmental compliance.
Proven at scale
From major industrial sites like the CERES Urea Plant to infrastructure projects requiring below-grade construction — dewatering coordinated with overall construction schedules so water control never slips the program.
