Needed a site evaluation and soil testing for a septic replacement in Manotick. Davis (C.E.T.) was incredibly thorough. His technical knowledge of septic design and local soil conditions saved us a lot of headache during the installation.

I hired Davis for a septic system design in Greely for our new build. As a BCIN-qualified designer, he made the permit process with the city seamless. He really knows the Ontario Building Code requirements. Highly recommend Devish Design Services!
