What does sewer replacement mean and when is it necessary?
Sewer replacement involves completely replacing existing sewer pipes and connections in your home or business. Sewer systems become worn over decades due to age, corrosion, root growth, or subsidence. This causes leaks, unpleasant odors, and can even damage the foundation. The risk of defects is particularly high in older neighborhoods where stoneware or lead pipes were used. Repair is sometimes possible, but in the case of structural defects or severe subsidence, replacing the entire sewer system is the only sustainable solution. We at Ontstoppen.nl For every sewer replacement project, ensure that the system meets current building standards and the requirements of the Building Decree. Municipalities such as Amsterdam, Rotterdam, and Utrecht have imposed strict requirements on sewer connections through Environmental Services and Waternet, specifically to prevent environmental problems and health risks.
How does the sewer replacement process work?
The process we use to replace a sewer system consists of several structured steps. This allows us to expertly tackle any type of sewer problem, whether you live in a terraced house, an apartment, or a detached house. We first thoroughly examine the existing pipe system. Using modern sewer cameras, we visualize the condition from the inside, pinpointing the exact location of the problems. You'll then receive a customized quote, detailing exactly which pipes, downpipes, or connections will be replaced.
- Inspection with camera: We identify hidden problems and prevent unnecessary demolition work.
- Quotation and planning: Transparent costs upfront, so you know exactly what to expect. No surprises.
- Demolition and replacement: Old pipes are removed, modern (PVC) pipes are installed and everything is professionally connected.
- Testing and delivery: The new system is extensively tested for leaks and then functions without any problems.
We also collaborate with suppliers like Wavin, DYKA, and Pipelife, meaning we only use high-quality sewer materials that come with long-term warranties. Our team always works quickly, efficiently, and with minimal disruption.

Types of sewer replacement and techniques used
There are several types of sewer systems that can be replaced. The most common types are off-site sewer systems, internal sewer systems, and combined systems, each with their own considerations.
- Replacing site sewerage: Underground pipes outside the house, often made of stoneware or concrete, are replaced with modern, root-resistant PVC or PP pipes.
- Replacing internal sewerage: Pipes in crawl spaces and wall penetrations. PVC is the new standard material due to its durability and ease of installation.
- Rainwater drainage sewerage: Additional adjustments are possible for separate discharges, in accordance with the requirements of Water Boards and municipalities.
We use specific techniques for each method:
- Open excavation: Suitable for sagging pipes. Groundwork with a mini-excavator, after which the old pipes are completely removed.
- Relining: Possible for slightly damaged pipes. We pull a plastic sleeve through the existing sewer, making the inside as good as new.
- Sewer replacement for private and business use: We choose the best method depending on your location and the type of problem.
Common causes for sewer line replacement
Reasons for completely replacing the sewer system vary. The architectural layout, building materials used, or external influences all create a variety of problems.
- Aging of materials: Stoneware, cast iron and lead can no longer meet modern water usage and are easily damaged.
- Root Growth: Tree roots enter pipes, causing cracks and blockages.
- Ground subsidence: Especially in peat and clay areas it occurs that sewer systems subside, resulting in leaks.
- Construction errors: During renovations or poor installation, kinks or subsidence can occur in the system.
Using smart inspection techniques like sewer cameras and smoke tests, we always pinpoint the problem to within a meter. This saves you unnecessary costs and labor.
