Wastewater Treatment: Collective vs. Non-Collective

Wastewater Treatment: Collective vs. Non-Collective

Posted on 10 Oct 2022 by Lise Helluy

There are two main types of wastewater treatment: collective and non-collective. The purpose of the wastewater treatment diagnosis is to decide which type of sanitation is best for your needs. There are many factors to consider when making this decision, such as the size of your property, the amount of wastewater produced, and the soil type. In this blog post, we will discuss the differences between individual sanitation and mains drainage.

1) What is the purpose of the wastewater treatment diagnosis?

The purpose of the wastewater treatment diagnosis is to decide which type of sanitation is best for your needs. There are many factors to consider when making this decision, such as the size of your property, the amount of wastewater produced, and the soil type.

There are two main types of wastewater:

  • Grey water from the sink, the washing machine, the kitchen...
  • Black water from toilets.

The sanitation diagnosis was thus set up to ensure that people don't fling waste straight into nature. The diagnosticians will examine the state and conformity of the house's drainage system to achieve this.

2) What are the differences between individual wastewater treatment and mains drainage?

There are two main types of wastewater treatment: collective and non-collective. The main difference between the two is that, with collective wastewater treatment, the water is collected and treated at a central location before being released back into the environment. Non-collective wastewater treatment, on the other hand, occurs when each individual property has its own wastewater treatment system.

Individual sanitation is possible when the house is located in an area without a collective network. Otherwise, the homeowner is under a duty to connect his property to it. Within two years after the network is completed around his home, the owner must connect his sewage system to it.

There are many advantages and disadvantages to both collective and non-collective wastewater treatment. Some of the advantages of collective wastewater treatment include lower costs, less maintenance, and fewer environmental impacts. However, one of the disadvantages of this type of wastewater treatment is that it can be less effective in areas with high levels of pollution. Non-collective wastewater treatment can be more expensive and require more maintenance, but it is often more effective in areas with high levels of pollution.

a) Individual:

This can include options such as a septic tank/primary tank, or a micro-station, a more ecological system. To avoid any penalties or fines, it is best to hire a professional company that is up-to-date with the current construction standards. The owner can technically take on the project themselves, but if the municipality finds any areas of non-conformity, they can order (and make the property owner pay for) corrective work.

Please be advised that you are only required to have a sanitation diagnosis when selling a building or house that has a non-collective sanitation system. The owner has four years to fix any detected non-conformities that could create a health hazard or environmental risk. If the owner plans to sell the property, they have one year to bring it into compliance.

b) Collective:

If not, then the owner of the said property must have it professionally done. Please keep in mind that the building must also have an autonomous sanitation system, even if it is connected to a collective sewerage system. This means that there must be both connections under the public road leading to the collective sewerage and under private property heading towards the autonomous system.

Non-collective networks are only necessary when the property is difficult to connect. In this case, it will be necessary to set up a non-collective network.

The sanitation diagnosis is optional even when selling a house connected to the sewerage system but is recommended regardless.

3) BIOROCK & BIOROTOR: non-collective and semi-collective treatment plants:

At BIOROCK, we have developed 4 types of wastewater treatment plants. All our wastewater treatment solutions are non-collective and can treat wastewater for homes ranging from 4 PE (Population Equivalent) to 240 PE. Our sewage treatment systems offer a simple yet effective process that requires no electricity, has no moving parts and needs minimal annual maintenance.

One of the main benefits of having a BIOROCK sewage treatment plant is that it’s a long-term sustainable and economic investment. BIOROTOR RBC system

BIOROTOR, on the other hand, is a semi-collective wastewater treatment plant that can serve multiple properties. This optimized RBC system is a fully automatic, modular, wastewater treatment system, that was expertly developed for communities of up to 10.000 PE. 

Both of these plants use natural processes to treat wastewater without chemicals or few energy, making them both eco-friendly options.
