Septic Separation Distance
Raised leaching and filter beds have increased separation distances. The elevation of finished grade minus existing grade x 2 is added to the minimum separation distances.
The difference between existing grade and finished grade elevation = 1.5 metres (5 feet) 1.5 metres (5 feet) x 2 = 3 metres (10 feet) Therefore, add 3 metres (10 feet) to all separation distances i.e., 15 metres (50 feet) to drilled well now becomes 18 metres (60 feet)
A properly functioning septic system will minimize the impact on water quality in lakes, rivers, wetlands, creeks and streams.
