The local picture around Launceston
Since 1 January 2020 a septic tank must not discharge directly to a watercourse — around Launceston that means the River Tamar, the River Kensey and the River Inny. A tank that still does needs upgrading to a treatment plant or a drainage field, and it usually surfaces at the point of sale. How the discharge rules work →
The Launceston district is Culm shale and slate country with mixed clay soils — percolation genuinely varies field to field, so neighbouring farms can need entirely different drainage designs. Everything here drains to the Tamar, whose catchment the Environment Agency monitors closely. What a percolation test involves → · BGS geology viewer
