Sewer cleaning

If there are branches, roots or other debris in the sewer, they must be cleaned to ensure proper functioning. If there is debris in the pipes, it can cause blockages and damage the sewer system. After a thorough inspection, contaminated sewers should therefore be cleaned. The Nordsee nozzle is suitable for this, for example, or the root cutter for large amounts of root growth.

Why clean the sewer?

Since sewer systems are difficult to see into, it is all the more important to check them regularly and clean them if necessary. Roots or other debris such as leaves or rubbish can damage sewage pipes or cause them to slowly become blocked. This endangers the functioning of the sewage system and poses a hygiene risk to humans and the environment. To prevent this from happening, sewer cleaning is often used as a preventive measure to avoid damage to the pipes and blockages.

How does sewer cleaning work?

Sewer cleaning is always preceded by a sewer inspection. This provides you with information about the condition of the sewage and sewer systems. If deposits are found in the pipes, sewer cleaning is recommended. This carefully removes leaves, branches and other materials so that the sewers function properly again and damage and blockages do not occur. Only then can further measures such as sewer rehabilitation or leak testing be initiated. Various techniques are used for cleaning:

The Seeing North Sea nozzle has proven itself for cleaning sewers. A camera is used here that documents the cleaning in the form of a video. Due to the real-time camera, this technology is also referred to as a “seeing North Sea nozzle”. The nozzle can be used flexibly and quickly, as the camera enables parallel work and visual observation. Even house connection pipes can be cleaned from the main sewer without entering the property. If damage is detected in the video recordings, inspection and flushing can begin immediately.

If there are large roots of trees or shrubs in the channels, the nozzle technology is usually too weak to remove them completely. However, ingrown roots can cause leaks and cracks in the pipe and must therefore be removed immediately. This is where the root cutter comes into play. The cutter removes all roots in the pipe completely, so that they can no longer cause damage. It also dissolves concrete, limestone and other stubborn deposits. First, the pipe section is inspected and any deposits are removed. Then either the electromechanical or high-pressure milling machine is used to remove the roots.

Storm water retention ponds can absorb large amounts of precipitation. To ensure that these basins can fully perform their function, they must be regularly inspected and maintained. This is because sludge and other materials affect the absorption capacity of the basin. The same applies to fire extinguishing basins if they are not covered and leaves or similar materials get into the water. Such basins are particularly important at recycling centers to extinguish highly flammable materials in an emergency.
 

Nehlsen undertakes the professional desludging of rainwater retention basins and fire extinguishing basins in this area, as well as the disposal of the sludge. The desludging of sediments from ponds, iron manganese sludge from drinking water treatment, sand trap residues and other industrial sludges are also part of our portfolio.

Nehlsen not only disposes of sludge from canals and rainwater retention or fire extinguishing basins, but also faecal sludge from small sewage treatment plants, sealed collection pits, from ships and from temporary containers of all kinds. This is because faecal sludge may no longer be disposed of in landfills, but must be disposed of properly. How exactly the sludge is disposed of must be discussed with a hazardous materials officer, if necessary, or determined by laboratory analysis.

After the analysis, we offer you a number of disposal options for sewage sludge and wastewater that meet all legal requirements. These include drying, mechanical dewatering and energy recovery. We are also happy to take over the delivery of activated sludge for you.

Difference between sewer and pipe cleaning

Unlike sewers, pipes are often connected to the floor, ceiling or walls. They are usually found in residential buildings and are cylindrical in shape. By contrast, sewers are wider in diameter than pipes and come in a variety of shapes, such as oval or rectangular. The water from residential buildings usually flows through the narrower pipes to larger sewers and then to sewage treatment plants. So when we clean pipes, we only clean the narrower pipes, and when we clean sewers, we clean the wider sewers.
