Percolation Soil
This product can be manufactured to provide the required Percolation rates in a Domestic Waste Water Treatment System. Onsite systems are the primary methods used for the treatment and disposal of domestic waste water in rural parts of the country. The percolation soil is tested to maintain a T-value of 1-50.

Testing had to be carried out to achieve the required T-soil value. Test holes were dug in-situ by the contract engineer, this will determine the overall T-value needed. This will determine the rate in which the waste water has until it is safe to meet the ground waste. Once the value is found, we can manufacture the soil with the correct T-value.

Percolation soil is designed to a specific T value range. This is to ensure adequate contact time for soil microbes to degrade any organic pollutants remaining in the waste water once it has passed through a treatment system. If the percolation media is too permeable the waste water will pass through too quickly and the soil microbes will not have sufficient time to break down any remaining pollutants.

If the percolation media is impermeable the waste water will not be able to infiltrate the media, which will lead to the formation of puddles and potential odour and other problems.

Enrich percolation soil is manufactured on a site by site bases. This means that a specific T value can be produced which is most appropriate for the in-situ material.

Enrich percolation soil is a blend of soil, angular aggregate and compost.
The respective ratios vary depending on the required T-Value.

The angular aggregate is a vital component as it provides greater porosity to the media. Angular material has a larger surface area than rounded material and hence gives more air space as well as a greater area for microbial activity.
The biological active compost contains a high population of microbes that increase the level of soil microbial activity and increase the potential for bio-degradation of organic pollutants remaining in the water.

The required portions of the three materials are thoroughly mixed using a Doppstadd drum screen to ensure uniformity and consistency.

Each batch is individually tested to ensure the required T-values have been attained prior to delivery.

Delivery
The soil was delivered by our own transport and a hired haulage company.
