SEPTIC TANK & DRAINAGE FIELD INSTALLATION

WHY INSTALL A SEPTIC PLANT WITH A DRAINAGE FIELD?

If your property does not have access to a watercourse, a septic tank with a drainage field can be an ideal solution. The drainage field allows wastewater to trickle down through gravel, effectively removing contaminants from the water before it enters the ground. This cost-effective option is fully compliant with the latest general binding rules and is ideal for those with ample space

If connecting to a drainage field is not feasible, it is no longer allowed to discharge wastewater from a septic tank directly into a watercourse. In this case, you will need to explore alternative solutions such as a sewage treatment plant.

When it comes to choosing the best solution for your needs, our team of experts is here to help. We can provide you with guidance and advice on the various options available, and help ensure that your drainage field complies with the General Binding Rules. Contact us today to learn more.

WHAT DOES IT DO?

With a septic tank system and a connected drainage field, domestic waste undergoes a two-step process that effectively cleans it to an acceptable level before releasing it into the ground.

HOW DOES IT WORK?

A septic tank digests organic matter and separates floatable matter (such as oils and grease) and solids from wastewater.

The treated wastewater flows into a drainage field built with solid slotted pipes surrounded by gravel. The drainage field aims to allow the wastewater to trickle down through the gravel, promoting the growth of bacteria on the gravel surface that removes contaminants from the water before it enters the ground.

WHAT NEXT?

Now that you have made the decision to install a septic tank and drainage field we would a suggest that you take a look at the General Binding Rules to make yourself aware of the rules and regulations surrounding wastewater, or take a look at our Frequently Asked Questions page.

1 WE WILL COME OUT AND SURVEY THE LAND

To determine the suitability of a septic tank system for your property, various factors must be considered. These include the volume of wastewater to be treated, the distance of the intended installation point from buildings, the location of the discharge point, the ground's porosity, and the size and placement of the drainage field.

2 WE WILL DESIGN THE SYSTEM

Our team will utilise the findings from the site survey to design a septic tank system that suits your property. We'll provide recommendations for the type of discharge method, depth and location of the tank, and positioning of the drainage field. It's critical to position the drainage field at least 10m away from any watercourse and 50m away from any water supply. During the design process, we'll consider the following factors to ensure the system is effective and compliant with regulations

3 INSTALLATION

We will create the groundwork and foundation for the new septic tank plant by excavating the hole and installing a base. After installation, the unit will be backfilled with concrete and finished off with topsoil and seed.

The drainage field will be excavated to the appropriate depth, and perforated pipes arranged in a herringbone pattern. The pipes will be surrounded by gravel and connected to the tank outlet. Finally, we will cover the site with topsoil and seed to complete the project.

4 OPERATION

A septic tank operates through gravity to separate solids. The lighter solids, along with oil and grease, will float to the surface, while the heavier solids will sink to the bottom of the tank. Though some of the 'sludge' will break down through natural bacteria, much of it will still remain and accumulate over time. Therefore, it is necessary to have your septic tank regularly emptied by a registered waste carrier.

The breakdown of this sludge is an essential part of the process so it is important that the bacteria in the tank that facilitate it must be protected.
