Sewer and Pipe Services

This method uses electrically powered spiral machines. Various attachments are used depending on pipe diameter and level of contamination to achieve optimal results. This approach is suitable where water-based cleaning is not an option or in tight, complex interior pipe systems. It is also used for individual pipes in kitchens, showers, or toilets.

Often a prerequisite and preparatory step for further work, this method uses pressurized water to flush out pipes and channels. It’s predominantly used for buried infrastructure and can include high-pressure techniques to remove debris and even roots.

The water used in hydromechanical cleaning must be extracted afterwards. Depending on the pipe or channel profile, various technologies are used. In large-diameter pipes, high-pressure flushing and vacuum vehicles are deployed.

Similar to water, all materials flushed from the sewer – such as sludge, sand, concrete, or roots – must be collected and disposed of, sometimes as hazardous waste. Most sewer companies offer this as part of their cleaning services.

Grease and oil separators or light liquid separators (e.g., for fuel) must be regularly maintained. This includes scheduled emptying, cleaning, and proper disposal of the collected substances.

If soakaways are blocked, they can no longer absorb rainwater, resulting in flooding. Regular maintenance and desilting prevent such issues.

Special remote-controlled camera systems are used to inspect non-accessible pipes and channels, assessing their condition and function. Some systems include locating transmitters and laser technology for enhanced analysis.

TV inspections can include measuring and documenting pipe runs, lengths, and connections. This information is used to create detailed layouts or even 3D models of the system – an essential step especially for in-house rehabilitation projects.

A method that uses visible signal smoke to locate incorrect connections between stormwater and wastewater systems. It helps detect whether and where rainwater is misdirected into sewage systems and vice versa.

Leak tests detect otherwise invisible damage or verify the integrity of previous rehabilitation work (e.g., installed liners). Water or air is typically used to test pipes, joints, lengths, manholes, or entire systems.

This test focuses specifically on the transitions between two pipe sections to check for watertightness and durability.

After heavy rainfall or blockages, wastewater can back up into a building’s drainage system, potentially flooding rooms via floor drains. Installing a backwater valve at the drain or inspection shaft can prevent this.

To block off sections of a sewer or pipe system, including manholes or inlets submerged underwater, special technology is required. In extreme cases, divers may be necessary to install closures safely.
