BCIN-licensed septic design and installation for rural properties, new builds and failed systems. One local, owner-operated team from soil test to final inspection.
Septic Tank Installation in Dunnville & Haldimand
A septic system is one of the biggest decisions on a rural property, and it has to be done right the first time. MXC Excavating handles the whole job as one turn-key service: we visit your property, run the soil percolation tests, complete the engineered design, file for the municipal building permit, excavate, install and arrange the final inspection.
We are members of the Ontario Onsite Wastewater Association (OOWA) and authorized installers for advanced tertiary systems including Eljen, Norweco, Bionest, Ecoflo, Enviro-Septic, Infiltrator and Waterloo Biofilter. That means we can offer more than one option when your lot is tight or the soil is tough.
