Groundwater Dewatering Studies

Kala has conducted numerous dewatering studies throughout the province of British Columbia.  These are either temporary, for example to assist with construction or permanent dewatering considerations for foundation engineering purposes. In addition, Kala provides solutions for groundwater dewatering for onsite wastewater disposal considerations.
