Sewer-TV-inspection

To prevent contaminated water from the sewage pipes from seeping into the ground and posing a risk to humans and nature, sewer systems must be regularly inspected. Sewer TV inspection has proven to be an effective way of examining the condition of sewage systems. During the inspection, a camera is used to view the sewer system in order to detect damage and, if necessary, to initiate further measures such as a leak test. Find out why sewer TV inspection is important, how it works and what other sewer inspection methods are available.

Why a sewer TV inspection?

Sewage systems are often convoluted and therefore difficult to access. Because they are underground, root ingrowth can occur, which can damage the pipe and contaminate the water. Other objects can also damage the pipe and cause blockages. To prevent this from happening, sewers must be regularly inspected and maintained. Only a professional sewer inspection can analyze the condition of the pipes and, if necessary, further measures such as a leak test or sewer rehabilitation can be initiated.

Sewer TV inspection: 
How it works

Sewer TV inspection is used to determine the condition of sewers. This is done both before and after  cleaning to assess damage and to verify the success of the measures. For the sewer inspection, cameras are used that can be easily operated even in narrow sections. They make videos of the sewer in real time.The inspection of the sewer network is carried out with various camera systems in ISYBAU format. We offer you a range of methods for inspecting sewers.

With Panoramo technology, dark shafts can be inspected quickly. Two high-resolution cameras scan the inside of the shaft in a few seconds and can detect damage in the sewer pipes. Another advantage of Panoramo technology: the 3D spherical image scanner produces a three-dimensional image of the shaft. The data collected by our state-of-the-art IBAK-PANORAMO-SI inspection vehicles can be used for subsequent measures such as sewer cleaning.

The deformation test is used during sewer TV inspection or separately to measure the diameter of a pipe. The mechanical scanning method is used to display the vertical and horizontal diameters as well as the upper and lower tolerance limits. The deformation measurement can be used in water as well as in humidity and steam. Temperature fluctuations do not affect the measurement results. 

The main areas of application for deformation measurement are determining the caliber and quality assurance for or after renovation work, as well as deformation measurement for quality assurance. The deformation test is TÜV certified and works with the DKM 150 (DN 150 to DN 400) and DKM 400 (DN 450 to DN 1200) measuring probes.

To determine whether there is any damage to the sewage pipes, incorrect connections, odour nuisance or unknown sewer lines, sewer fogging or external discharger testing is carried out. In this process, fog is introduced into the sewer system through municipal manholes. This fog escapes from faulty connections at gutters or floor drains. The external discharger check is characterized by low time and personnel requirements. The procedure is commissioned by the municipalities.
