Percolation Tests

A percolation test is an essential part of any off mains drainage system installation to make sure you get as many trouble-free years of service from the system as possible. Our team can undertake this important assessment for you.

What is a Percolation Test?

Soakaway systems can be used to take the wastewater from either a septic tank or a sewage treatment plant. It’s a network of perforated or slotted pipework which allows the wastewater to percolate (or filter through the porous surface) safely through the ground without causing pollution.

A percolation test is a way of assessing the ground conditions at a property to determine what type of soakaway arrangement might be suitable. If found to be suitable for a drainage field, a percolation test also helps to determine how big it needs to be.

FAQs

When are they required?

A percolation test should always be carried out if a drainage field or soakaway is due to be installed at a property. A percolation test is not required for a sewage treatment plant to discharge straight to a ditch or a watercourse.

Do weather conditions affect percolation tests?

Yes, weather conditions can affect percolation test results, which should not be carried out during periods of heavy rain.

In what instances would a percolation test fail?

A percolation test would fail if the water drained away too quickly or too slowly from the test pits. A test would also fail if the test pits filled with groundwater immediately following excavation.
