Garden Route Septic Tank Installations: Soil Percolation Testing

Garden Route Septic Tank Installations runs percolation tests ahead of any septic installation involving a soakaway, across Mossel Bay, George, and the surrounding Garden Route. It’s a short, practical test that removes the guesswork from a decision that’s expensive to get wrong.

Why test instead of just judging by the neighbourhood?

Because soil conditions vary more than most people expect, sometimes across a single stand. Two properties a street apart can have genuinely different drainage rates depending on fill soil, underlying rock, or how close the water table sits to the surface. A percolation test measures your specific site, not a general assumption about the area.

How long does the test take, and does it delay the job?

The test itself takes a few hours, mostly waiting for water to drain at a measured rate, and it’s done before we quote the drainage field design, not as an afterthought once installation has started. Building it into the process upfront generally saves time overall, since it avoids designing a field that then needs reworking.

Can the test result mean the property can’t have a septic system at all?

In rare cases, yes, if drainage is extremely poor and a conservancy tank isn’t practical either. This is uncommon, and it’s exactly the kind of situation worth knowing before committing to any system rather than finding out after installation.
