Onsite Wastewater Treatment Systems

Groundwork Engineering Limited is a leader in the design of Onsite Wastewater Treatment Systems (WWTS).  Innovative wastewater treatment system designs are developed to deal with effluent disposal limitations, site restrictions and client requirements.  With a wide range of treatment technologies available, it is important that the most appropriate technology be selected for each site.  Projects have been completed for applications such as single family homes, senior citizen homes, schools and seasonal campgrounds with design flows ranging from 1,500 litres/day to 150,000 litres/day.  We assist clients in obtaining necessary approvals from local and provincial authorities.  We provide maintenance and inspection services for new and existing systems. Groundwork Engineering is a member of the Ontario Onsite Wastewater Association (OOWA).
