Septic services in Tavistock & surrounding rural parishes
Tavistock is the Devon side of the Tamar valley — the same mining country, the same South West Water network and easy range for the tanker firms working east Cornwall. The surrounding parishes of Lamerton, Milton Abbot, Mary Tavy and the Dartmoor-edge hamlets are largely off-mains, on septic tanks and treatment plants.

The local picture around Tavistock
Since 1 January 2020 a septic tank must not discharge directly to a watercourse — around Tavistock that means the River Tavy, the River Walkham and the Tamar itself at Gunnislake. 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 →
Tavistock sits where Dartmoor's granite meets the mining ground of the Tamar valley — the same World Heritage mining landscape as Gunnislake and Calstock across the river. Shallow granite on the moor side, mine-disturbed land in the valley and steep plots each complicate a soakaway in their own way; everything here drains to the Tavy and the Tamar.
