Industrial wastewater can enter the environment a number of ways including direct discharges to waterways, indirect discharge via municipal sewer systems, and discharge through precipitation runoff from a contaminated site into storm sewers, open ditches and groundwater regime.  These industrial wastewater discharges may contravene municipal by-laws, the Ontario Environmental Protection Act and the Ontario Water Resources Act.  The discharge of contaminants via these routes can be controlled through in-plant modifications, effluent pre-treatment and site management.
 

In addition to surface water treatment DCS applies its knowledge of treatment systems to the treatment of contaminated groundwater. Following completion of hydrogeological studies the appropriate treatment technology is chosen and integrated into a treatment program.  The program is designed to permit discharge of treated water to a plant treatment system or to the municipal sewer system.

DCS provides a full range of services for the investigation and treatment of both surface and groundwater regimes.  These services include:

• flow measurement and sampling;
• preparation of Site Best Management Plans;
• regulatory approvals;
• sewer-use compliance investigations;
• in-plant waste treatment;
• treatment technology assessment;
• surface water discharge studies;
• storm water quality and quantity discharge management; and
• contaminated groundwater recovery and treatment.
