It is important to be aware that a lot will not be accepted if the minimum requirement of 1 foot of *acceptable soil above bedrock or the water table over an area large enough to accommodate a septic field, typically a 25 x 65' or greater rectangular area is not met. A slow rate of percolation and/or an increasing number of bedrooms in a cottage or dwelling will require a larger area.

*(soil exhibiting favorable percolation rates and granular structure and not having excessive rock content) .

A septic system designed is required for crown applications, Hydro hookup′s, building permits, mortgages etc.
