Dewatering

GAIA has the capability to design, build and operate innovative groundwater dewatering control systems. By integrating Golder’s in-house hydrogeology and civil engineering capabilities with GAIA’s practical approach to dewatering, we can custom-design effective site-specific solutions that meet our client’s objectives.

These solutions may include:

• Deep wells
• Vacuum wells
• Wellpoints
• Eductors, or
• Electro-osmosis

These are installed either as stand alone systems or in conjunction with other groundwater control measures such as:

• Ground freezing
• Grouting
• Deep soil mixed walls
• Sheet pile walls
• Caisson walls
• Slurry walls, or
• Diaphragm walls

The guiding design criteria for all our systems are ease of optimization, operation and maintenance, use of off-the-shelf components whenever possible, and cost. We also recommend and incorporate the appropriate real-time monitoring programs and redundancy into the systems to mitigate against the consequences of a full or partial system shut down.
