Pipe Cleaning
High Pressured Water Jetting with Vacuum
Applus+ Velosi cleaning trucks are a combined high pressure water jetter with
vacuum. The jetter will remove all debris including sand, silt, roots, scale and
grease from inside the pipelines. The vacuum will lift all these debris from the
manholes into the waste tank.
Adjustable water pressures and cleaning nozzles can be used that will be suitable
for all pipes.
6 Pipeline Rehabilitation
CCTVApplus+ Velosi has a number of camera systems which range from 80 mm to 1600 mm
pipe diameters.
CCTV surveys determine the condition of the inside of the pipe, we also offer the
following:
1. Pipe deflection (Ovality)
2. Internal pipe measurements
3. Lateral pipe connection measurements
4. Tilt surveys
5. Joint gap measurements
All reports are coded to EN 13508 standard.
Our operators and reporters are certified to MSCC4 (WRC).
8 Pipeline Rehabilitation
CIPP/GRP Lining
Glass Reinforced Pipe, UV Technology
A cured-in-place pipe (CIPP) is one of several trenchless rehabilitation methods
used to repair existing pipelines. CIPP is a jointless, seamless, pipe-within-a-pipe
with the capability to rehabilitate pipes ranging in diameter from DN 100 to DN
1600. The process is carried out through the manholes, avoiding excavation and
traffic congestion.
There are several different materials and methods of curing, Applus+ Velosi are
lining with glass reinforced liners which are cured using UV technology. The majority
of pipes being rehabilitated using CIPP are sewer and drainage, these lines will have
internal failings and infiltration problems. Once lined these pipes will be good for
another 50 years.
10 Pipeline Rehabilitation
Patch Repair
Localized Structural CIPP Repair
The patch repair system provides a localized repair within an existing pipeline. It
is quick to install and offers little disruption to property, services and traffic.
The patch is installed through the manhole avoiding any excavation and
replacement costs.

Pipeline RobotsApplus+ Velosi has several robots that were designed for rehabilitation works
inside sewer pipes ranging from DN 100 to DN 1000.
Various tool attachments permit the sewer robot to perform milling, grinding,
filling and injection operations. Mainly obstacles such as misplaced pipe
connections, roots, encrustations, concrete blockages and deposits, as well as
opening laterals after patch repair and CIPP lining.

Manhole Inspection and RehabilitationManholes are becoming increasingly in need of repairs due to infiltration and traffic pounding.
Once the manhole inspection has been carried out a rehabilitation method can be chosen.
The choices are as follows:
1. Cured-in-Place Liners
2. Cementitious Coatings/Grouts
3. Polymer Modified Coatings

Pipe Bursting Pipe bursting and pipe splitting are trenchless methods used to replace existing pipelines in the
same alignment without physically removing the existing pipeline. Bursting and splitting by using
the existing alignment to replace a pipe avoids the need to secure additional right-of-way to
install the replacement pipe. Bursting and splitting can be used to upsize the pipeline, increasing
its flow capacity.
Pipe bursting was initially developed in the 1980s to replace small diameter cast iron gas
distribution lines, but has since grown in acceptance as an effective method for replacing
pipelines diverse in size, material type, and functions.
Pipe bursting is used to replace all pipes such as clay, concrete, steel and cast iron through the
application of a static or pneumatic bursting head to fragment the existing pipe. Simultaneously,
a new product pipe attached to the back of the bursting head is installed in the same alignment
as the original pipe.

Close Fit LiningClose fit lining is a term used to describe a range of techniques for renovating
pipelines, in which the cross section of the liner is temporarily deformed
before insertion into the carrier pipe. The liner is subsequently restored close
to its original diameter, forming a close fit with the original pipe.
The liner is deformed by either reducing its diameter or changing its shape. To
do this the liner can either be passed through tapered dies, through rollers or
be folded, either on site or in the factory. After insertion into the carrier pipe
the liner is reverted, either by natural relaxation or through the application of
steam or water under pressure. Each close fit lining system uses a different
combination of deformation and reversion methods.
The different types of close fit lining systems that are currently available are:
• Deformed Pipe
• Die drawing
• Rolldown
