Understanding Percolation Tests and their Importance in choosing a Klargester Sewage Treatment Plant
Percolation tests play a crucial role in assessing the suitability of land for the installation of sewage treatment plants if a watercourse isn’t available, particularly in rural or undeveloped areas where municipal sewage infrastructure may be lacking. These tests help determine the rate at which water infiltrates or percolates through the soil, which in turn informs decisions about the design and installation of off mains drainage solutions, such as Klargester sewage treatment plants.
What is a Percolation Test?
A percolation test, also known as a perc test or a soil infiltration test, is a procedure used to evaluate the ability of soil to absorb liquid, typically wastewater from septic or sewage treatment systems. The test involves digging 3 holes in the ground, filling them with water, and then measuring the rate at which the water infiltrates into the soil. The results of the test provide valuable information about the soil's porosity, permeability, and overall suitability for the disposal of wastewater.
How is a Percolation Test Carried Out?
The following steps outline the typical process of conducting a percolation test via our Klargester Installer network:
Site Selection: Identify the location where the sewage treatment system will be installed. This should be representative of the area where wastewater will be discharged.
Digging Test Holes: Excavate one or more test holes of specific dimensions, usually down to the depth of where the drainage field will start typically around 1000mm, depending on local regulations and soil conditions. At the level of where the drainage field will be located you dig a 300x300mm hole and put a marker in at 75mm & 225mm from the bottom.
Pre-Saturation: Fill each test hole with water and allow it to saturate the soil overnight to ensure that the soil is fully moistened before conducting the test.
Measuring Water Level: Fill each test hole with water to a predetermined level and mark the starting water level.
Monitoring Water Level: Time the drop in water level from 225mm to 75mm which is the middle 50% of the percolation hole.

Importance of Percolation Tests in Choosing a Klargester Sewage Treatment Plant
Percolation tests are integral to the selection and design of sewage treatment systems, including Klargester treatment plants, for several reasons:
Regulatory Compliance: Many local and national regulations require the evaluation of soil percolation rates before approving the installation of sewage treatment systems. Compliance with these regulations is essential to ensure environmental protection and public health.
Optimal System Design: The results of percolation tests if carried out correctly will allow the treated effluent to discharge into the ground over a 24 hour period at a controlled rate based on the number of people using the facilities each day.
Prevention of Environmental Contamination: Inadequate percolation rates can lead to the improper disposal of wastewater, resulting in contamination of groundwater, surface water, and soil. By assessing soil permeability through percolation tests, the risk of environmental pollution can be mitigated.
Long-Term Performance: Choosing a sewage treatment system without considering soil characteristics can result in poor performance and costly maintenance issues over time i.e. systems flooding or surcharging back into properties. By conducting percolation tests and selecting a Klargester treatment plant accordingly, property owners can ensure the long-term effectiveness and reliability of their sewage treatment infrastructure.
In conclusion, percolation tests are essential tools for evaluating soil suitability and selecting appropriate sewage treatment solutions such as Klargester treatment plants. By providing valuable insights into soil permeability and absorption rates, these tests enable informed decision-making, regulatory compliance, and the protection of public and environmental health in areas without access to centralized sewage infrastructure.

How to Choose an Off-Mains Wastewater System
If your house cannot connect to the mains sewer then you will need to treat all your wastewater within the bounds of your property.
Domestic Wastewater Treatment Plant vs Septic Tank - which to choose?
In most scenarios, we advise that homeowners opt for a treatment plant. Read on to find out why.
Installing & Maintaining your Off-Mains Drainage Field
Drainage fields are strictly regulated. If your drainage field was installed after January 2000, then it will fall under H2 Building Regulations.
A Guide to Wastewater Treatment Systems and Drainage
Around 1.5 million homes in the UK are not connected to the sewer because of where they are situated, typically in remote or rural areas.
