Before any septic tank or sewage treatment plant can be installed, a professional construction survey and percolation test is required to establish whether your land can support a compliant drainage field. Lancashire Septics Ltd carries out full site assessments and percolation tests to British Standard BS 6297 across Preston, Blackpool, Lancaster, Blackburn, Chorley, and the surrounding areas of Lancashire.
Our experienced engineers visit your site, conduct soil percolation tests at the correct depth and volume, and assess ground conditions to determine drainage field suitability. You receive a clear written report detailing results, recommended drainage field dimensions, and any planning considerations — exactly what your local authority or building control officer will expect to see.
