Drainage Fields

What is a drainage field?
A drainage field is a looped section of slotted pipes (also known as perforated pipe) in the ground, surrounded in, and laid upon a bed of gravel. The aim of a drainage field is to allow wastewater to make it’s way through the gravel allowing bacteria to form on the gravel. This helps to remove contaminants from the water prior to it entering the ground surrounding the drainage field. Also, to give treated water (in the case of a treatment plant) a sufficient area to disperse evenly.

How large are drainage fields?
Drainage fields come in different sizes depending on the amount of usage it will see and what the ground type is. For example, if you have a lot of clay underground, your drainage field would be larger than someone who has a lot of sandstone even if you had the same usage. The best way to determine the size your drainage field should be is to calculate the amount of usage your system could have and then run percolation tests.

What is a percolation test?
A percolation test determines the rate of water absorption into the ground. The test measures how long it takes water to drain away from a saturated hole dug into the ground; the result determines both the suitability and permeability of the soil, and ensures that the ground has sufficient drainage capacity to handle the amount of water that will come from the drainage field intended to be installed.

Percolation tests

On paper, Percolation tests appear to be easy to test if you wish to have a drainage field for your sewage treatment plant. However, the test must be carried out with pinpoint accuracy to determine the porosity of your ground. Fortunately, at Sussex Water & Drainage, we have all the equipment and knowledge to ascertain Vp measurements accurately.

The percolation test involves excavating a 300mm square hole to a depth of 300mm below the proposed invert level of the discharge pipe. After carefully removing all loose debris, we will fill the void with water to the top of the 300mm mark and leave this to seep away overnight. We will then return and fill to the same point and closely observe its time from 75% capacity to 25% capacity. Using a calculation of how much water has dispersed in the given time with the depth lost, we can accurately read the average time in seconds (Vp) for the water to drop by 1mm.

Main sewer connections

Regardless of whether you have just purchased a new home or if you have an existing external sewage system that needs connecting to the main sewer, our fully equipped drainage experts can make this change for you.
