Percolation - land character

    Hi, has anyone who has been through percolation testing looked at the characteristics of the land on which the percolation test was carried out? The reason I ask as that the site we hope to carry out percolation on appears to have have bedrock across a section of it - not the whole site. This is visable via public maps online. Will bedrock limit the soils ability to percolate the water? Have limited knowledge in this area so my question may be moot.

    Possibly, but you can't quantity anything unless you've had representative tests done.

    The percolation test takes account of all of that.

    The first thing considered in a site suitability assessment for a percolation area is the type of soils/subsoils present and their thicknesses... if there's suspected bedrock outcrop on your site then that's a problem, you can't locate a percolation area within bedrock, you need a certain thickness of subsoils over bedrock to 'percolate' through.

    The Geological Survey maps available online are guideline only, they might not be correct on a local level. I suggest you confirm the depth to bedrock across your site, easily done with a shovel or mini-digger. Maybe there are areas with thicker subsoils that might be suitable? There are also options for raised percolation areas/beds above ground level if the subsoils are very thin.
