The Marquis Group has 13 sewer vehicles specially designed for contracts in the construction, commercial, industrial, chemical and public sectors. Our vacuum and rinsing trucks are ideal for cleaning work and the subsequent removal of sludge. The different vehicles are used according to the requirements.

The decisive factors for choosing the emergency vehicle are pipe diameter, type and degree of contamination, specific requirements and of course the local conditions. Thanks to the suction hoses with long reach, the vehicles can be installed quickly. Large suction tank volumes of up to 14,000 liters also make for effective collection tours.

Suction and rinsing truck brochure

The Federal Office for the Environment (FOEN) and the Basel Land Office for Environmental Protection (AUE BL) have drawn up new guidelines for emptying road manholes. The guidelines state that no contaminated backwash water may be drained into the manholes when they are emptied. This means that the sludge collectors have to be emptied by officially approved suction recycling vehicles. As an innovative company, Rohrputz-Loriol AG started developing its own suction recycling vehicle many years ago. This vehicle, which meets the requirements of Swiss legislation, can de-water the sludge on site, recirculate the water and dispose of the sludge, which has thus been reduced in volume, in an environmentally friendly and legally compliant manner. Rohrputz-Loriol AG is currently working with several special vehicles in the field of sewer cleaning and emptying of road manholes in the service of cantons and municipalities.

Rohrputz-Loriol AG offers our customers extensive services in the field of extraction. With our special machines, we can exhaust the following areas, among others, and thus ensure more safety:

• Stormwater retention basins
• Roof water collector
• Seepage shafts and pits
• Ponds, pools, and Biotopes
• Oil and petrol separator
• Fat separator
• Septic tanks
• Mud drilling etc.

We use a wide variety of suction vehicles for the various jobs, which are optimally specialized for the individual areas.

We empty, clarify and fill industrial collectors in one operation on site. In the special vehicle, the polluted water is separated and clarified on the spot in a physical-chemical process turning it into solids and liquids. The treated water meets the discharge requirements of the Water Protection Ordinance and can therefore be returned to the system. Only the significantly smaller amount of solids has to be removed and disposed of.

Suction and flush recycling

As pioneers in the field of research and development of "mobile waste treatment plants", we use the latest recycling vehicles developed to meet the needs of the Swiss market. We offer a unique, economically and ecologically aware sewer cleaning service.

Reducing the volume of waste by de-watering and conditioning the waste mass on site. Savings in disposal and transport costs. Use of the solids to generate renewable energy. With a recycling capacity of up to 900 liters per minute, these vehicles make a valuable contribution to environmental protection in addition to their excellent cleaning properties.

Suction recycling
A chemical-physical treatment plant separates sludge from water. The clean water returns to the separator, only the sludge is disposed of.

Rinsing water recycling
One-time refueling with fresh water. The rinsing water that is sucked up is constantly being physically processed and reused.

Only high-tech equipment, professional tools and well-trained employees enable efficient and high-quality investigations and the location of shafts. Whether professional sewer TV inspection, leak tests or data transfer VSA-KEK 2008 into the GIS expert system for operators of the WebGIS platform Geoportal, the Rohrputz Loriol sewer TV department with its fully equipped digital TV buses offers all these services from a single source!

TV bus with “explosion-proof system”
This sewer TV bus is equipped for areas of application with an increased risk of ignition such as gas stations, garages, chemicals, industrial, tank farms, etc. The entire camera system, pan head camera and steerable camera trolley with tilting option, is "explosion-proof" according to the II 2 G Ex px IIB T4 Gb standard. A 300-meter-long trolley cable, swivel head camera with integrated location transmitter, a high-pressure flushing unit, various cleaning nozzles and much more enable all types of work to be carried out in one operation.

Sewer TV inspection

With today's camera systems, several branch lines can be examined via the main line. Access via downpipes, washing troughs, etc. is no longer necessary. This can be done with a pin on the head of the camera, or when examining house connections from the municipal or city sewer using a satellite camera trolley with an additional sliding unit. The recording always takes place against the direction of flow.

On the trail of leaks with high-tech techniques

A sewer TV camera only provides visual information about the tightness of a sewer. A leak test must be carried out to check whether a repair site is actually leak-tight after a renovation. Rohrputz-Loriol is recommended as an accredited, neutral and independent testing center.

Sludge transport and disposal

We also take care of the disposal of all kinds of sludge and wet waste for our customers. Thanks to our special vehicles and thanks to the experience of our employees, we can ensure that the various wet wastes are disposed of professionally and in an environmentally friendly manner and, if necessary, also clarify them on site. This is how we at Rohrputz Loriol AG avoid contamination of soil and water during all our work. Use our consulting services to contact us. As a waste disposal company, we are happy to support private individuals, companies and communities with our knowledge and experience.

Drilling mud disposal

Do you have to dispose of drilling mud from flushing or hammer drilling contaminated with bentonite, cement or other additives? We have a treatment plant for de-watering liquid drilling mud. We are your partner when it comes to professional drilling mud recycling! Ask us for prices!

During persistent good weather conditions, the ground becomes dry and therefore hard. This makes it easy to reach lines and manholes that are normally only accessible with a heavy truck suction/flushing vehicle with additional tools (hoses, special reels, etc.) or not at all. During this time, reservoir overflow lines, field drainages and field path shafts can be optimally cleaned.

Pond and natural pool cleaning

Ponds or biotopes are exposed to strongly changing conditions. This habitat therefore places very high demands on its plant and animal inhabitants. Without regular cleaning, they are deprived of their basis of life when organic components such as leaves, dead aquatic plants or fish excrement sink to the bottom and start to rot. This is because substances are formed that are hostile to plants and aquatic animals, such as methane or sulfur compounds. The winter months are ideal for cleaning, because then fauna and flora take a break. Use this period and bring your pond or biotope back into ecological balance with the specialists from Rohrputz Loriol AG.

Die VSA-Richtlinie «Unterhalt von Entwässerungsanlagen (Hauskanalisation)», empfiehlt eine Spülung der Abwasserrohre alle 3 – 5 Jahre. Gerne beraten wir Sie auch diesbezüglich, sodass die Kosten für Sie planbar sind.

House connection investigation

The house connection is the section of pipe between the building and the municipal sewage system. Or the line between the last manhole on your plot and the community sewer. Access is via an inspection opening or control shaft.
