You live in an apartment complex and there's a sewage problem. The drain from your neighbours on the second floor overflows into your apartment on the first. Or the main stack pipe in the stairwell is leaking. Who is responsible? The apartment owner, the Homeowners Association (VvE), or both?
This is a question that often leads to discussions within Homeowners Associations. However, the answer is usually quite clear if you know where the line lies between common and private areas. In this article, we explain how responsibilities are divided, what the division regulations state, and how you, as a VvE board member, can maintain control over sewage maintenance.
Common vs. Private: Where is the Line Drawn?
The core of the matter revolves around the division regulations. This is the legal document that determines which parts of the building are common and which are private. For sewage systems, this distinction is made as follows:
Common Sewage System includes everything that serves multiple apartments or is located outside of private areas:
- The main stack pipes (vertical drain pipes that run through multiple floors)
- The main sewer lines under the building
- The connection to the municipal sewer system
- Shared pipes in crawl spaces, basements, and shafts
Private Sewage System includes the pipes that serve only your apartment:
- The drain pipes from your sink, shower, toilet, and washing machine up to the connection to the main stack pipe
- Siphons and odour traps within your home
- The connection of your private pipe to the common pipe
In practice, this means: as soon as a pipe serves multiple apartments or is located outside the walls of an individual apartment, it is a Homeowners Association matter.
Who Pays for What?
The distribution of costs generally follows the same lines as responsibility:
The Homeowners Association pays for:
- Maintenance and repair of common pipes (main stack pipes, main sewer)
- Preventive cleaning of the common sewage system
- Camera inspections of common pipes
- Replacement or renovation of outdated main stack pipes
The individual owner pays for:
- Unclogging of their own drain if the cause is in the private pipe
- Repair of pipes within the individual apartment
- Replacing siphons, faucets, and connections
It becomes more complicated when the cause isn't immediately clear. For example, if there's a blockage and water overflows at a resident's apartment on the first floor, but the cause is in the main stack pipe, then the VvE pays, not the individual resident. A camera inspection can reveal the exact location of the problem and who is responsible in such cases.
What do the deed of division state?
The deed of division is the guiding document. In the Netherlands, various model regulations are in circulation (1973, 1983, 1992, 2006, 2017). The newer versions are generally clearer about how maintenance responsibilities are divided.
Most model regulations state that the owner is responsible for the maintenance of “installations that exclusively serve their private section.” As soon as a pipe also serves other apartments, it falls under common maintenance.
However, there are still some grey areas. For example:
- The connection point. Where does the private pipe end and the common one begin? For some VvEs, this is the apartment wall; for others, it's the point where the pipe reaches the main stack pipe.
- Damage due to negligence. If a resident consistently flushes grease or wipes down the drain, causing a blockage in the main stack pipe, the VvE can recover the costs from that resident.
- Renovations. If an owner has renovated the bathroom and altered the drainage system, they are responsible for any problems that arise as a result.
Are you unsure about the division of responsibilities? Always consult the deed of division of your own VvE. If there's any ambiguity, the VvE manager or a legal advisor can provide clarity.
Common drainage problems in VvE complexes
Apartment complexes have their own specific types of drainage problems. Due to shared pipes and the age of many complexes, certain issues occur more frequently:
Clogged main stack pipes
Main stack pipes are the vertical drainage pipes that connect all floors. Through years of use, grease, limescale, and other deposits build up. Eventually, water no longer drains properly, and residents on lower floors experience water backing up. A professional drain cleaning is then necessary to clear the pipe.
Root intrusion
In older complexes with a garden or courtyard, tree roots can penetrate the drainage system. They seek moisture and grow into the pipe through small cracks or seams. This can lead to blockages and eventually to pipe breakage.
Aging pipes
Many apartment complexes from the 1960s and 1970s still have their original cast iron stack pipes. After 50+ years, these are often severely corroded by rust. Replacement is then the only long-term solution.
Drainage odor in the stairwell
Odor nuisance in common areas often indicates a problem with ventilation or a dried-out trap. Read more about the causes in our article on drainage odor in the home.
Preventive maintenance: why it pays off
Many VvEs only address drainage problems when it's too late: a resident experiences water damage, there's an odor nuisance in the stairwell, or a costly repair suddenly arises. This is understandable, as drainage maintenance isn't the first thing that comes to mind. However, reactive maintenance is almost always more expensive than preventive maintenance.
For example, a preventive cleaning of the main stack pipes in a complex with 20 apartments costs a fraction of what you'd pay for an emergency call-out where multiple homes have water damage. Add to that the consequential damage (floors, ceilings, insurance claims), and the price difference is enormous.
What does preventive drainage maintenance entail for a VvE?
- Periodic Cleaning. Have the stack pipes and main sewer cleaned every two to three years. This prevents deposits from building up and causing a blockage.
- Camera Inspection. A camera inspection provides insight into the condition of the pipes. You can spot root intrusion, cracks, sagging, or buildup before they become a problem.
- Maintenance Contract. Many sewer companies offer contracts for periodic maintenance. This provides certainty regarding costs and scheduling.
- Include in the Multi-Year Maintenance Plan (MJOP). Include sewer maintenance and replacement in the multi-year maintenance plan. This way, you allocate budget in time and prevent a large expense from coming as a surprise.
Tips for Homeowners' Association (VvE) Board Members
As a Homeowners' Association (VvE) board member, you play a key role in the sewer maintenance of the complex. Here are a few practical tips:
- Assess the condition of the sewer system. Don't know how old the pipes are or when they were last cleaned? Have an inspection carried out. This will give you a starting point.
- Communicate clearly with residents. Explain what constitutes common maintenance and what is individual. This prevents discussions when a bill arrives.
- Reserve Budget. Ensure there is sufficient room in the reserve fund for sewer maintenance. Replacing a stack pipe can cost tens of thousands of euros if you postpone it until damage occurs.
- Choose a Reliable Sewer Company. Work with a company that has experience with Homeowners' Association (VvE) complexes and is transparent about costs. Avoid surprises by agreeing on a fixed price beforehand.

Frequently Asked Questions about Homeowners' Association (VvE) Sewer Maintenance
Is the Homeowners' Association (VvE) always responsible for the stack pipe?
Yes, in most division regulations. The stack pipe serves multiple apartments and therefore falls under common maintenance. Check your own division regulations for the exact agreements.
Can the Homeowners' Association (VvE) recover costs from an individual resident?
Yes, if it can be demonstrated that the resident caused the problem through negligence or improper use. Examples include regularly flushing grease or wet wipes. A camera inspection can help determine the cause.
How often should the sewer system in a Homeowners' Association (VvE) complex be cleaned?
A good guideline is once every two to three years for the stack pipes and the main sewer. For older complexes or those with known issues, annual cleaning may be advisable.
What does sewer maintenance cost for a Homeowners' Association (VvE)?
That depends on the size of the complex and the type of maintenance. Preventive cleaning of stack pipes is significantly cheaper than an emergency repair for water damage. At RBNL, we work with fixed rates and provide a quote beforehand so you know exactly what to expect. Call us at 085 303 9999 for a no-obligation consultation.
Should sewer maintenance be included in the Multi-Year Maintenance Plan (MJOP)?
It is highly recommended. By including sewer maintenance and potential replacement in the multi-year maintenance plan, you allocate budget in time. This prevents the Homeowners' Association (VvE) from facing an unexpected large expense. In our next article, we will delve deeper into how to set up an MJOP for the sewer system.
