PRO Manholes and Inspection Chambers

Faster installation with lower rollout costs and longer service life

Pipelife's Manhole and Inspection Chamber Systems are designed to provide access to sewer or stormwater systems for inspection, maintenance, cleaning and sampling. Pipelife Chambers and Manholes are available in the dimensions 315 to 1000 mm.

Pipelife PRO chambers are engineered with polypropylene thermoplastic to meet tough strength and utility requirements. They provide the ideal solution for sewage and stormwater applications in various ground and water conditions. They connect easily to our Pipelife Pragma® and smooth pipes and are an important part of the Raineo® rainwater management solution. 

Take a look at our Composite Covers and Grates to complete your PRO System with equivalent high quality and a 400 to 800% longer service life than traditional materials.

Common applications include:

  • CCTV inspection points
  • Cleanout access
  • Intermediate access points in long pipe sections
  • Monitoring and effluent sampling points

PRO benefits at a glance

  • Developed from system-wide thinking

    The Pipelife PRO inspection chamber and manhole series is the latest and most innovative iteration of our continuous development process. Through talking with customers, learning from experience and monitoring climate, urbanisation and other trends, we're continually advancing the design of our chamber systems from construction, inspection and cleaning perspectives. We are also always looking for ways to speed up installation and improve overall integration across the entire pipeline system.

  • Lightweight and long-lasting

    Pipelife PRO inspection chambers and manholes are available in dimensions of 630 mm, 800 mm and 1000 mm. We make them from 100% virgin polypropylene (PP), a lightweight yet tough material that guarantees high durability and a long working life of over 50 years. Being virgin material, we can colour our components red-brown, which is better for visual inspection than low-contrast black, a by-product of using recycled materials.



  • Chemical resistant pipes

    Schiphol Trade Park, near Amsterdam Schiphol Airport, has been developed to be the most sustainable industrial park in Europe. With this challenge in mind, our customer proposed Pipelife PP pipes and connection pieces, and Pipelife Renoflow inspection chambers. PP offers better chemical resistance than PVC (including against kerosene, a key calamity-planning issue near an airport), shows higher impact resistance and is 100% recyclable.

  • Smaller crews and faster installation

    The result is what you should expect of a modern manhole solution: easier and so faster installation, using smaller crews that reduce overall project costs. Pipelife PRO chambers are ideal for use as TV inspection access points, line clean-out access, interim access points in long pipe sections, effluent sampling stations and monitoring pits.

21st century design

Every element of the PRO manhole system has been designed from the customer point of view. Our goal is to add value by focusing on overall system and project cost, ease of installation and operation, and long-term life expectancy and sustainability.

  • Built to resist

    Every PRO manhole is strong enough to withstand heavy traffic (Class D, 400kN), earth loads and 5 meters of groundwater pressure. Our chambers also withstand high temperatures, are 100% water resistant, provide excellent chemical resistance in aggressive environments, and they don't crack in the face of demanding freezethaw cycles.

  • Built to adapt

    The telescopic riser and cover allows flexibility during warm and cold months, which helps to reduce road deformation and cracking. Inherently, this solution can decrease maintenance costs and ensure a longer roadway lifespan. Via the support ring the weight on the cover is also transmitted into the ground, rather than onto the manhole, while the ribbing on the outside of the chamber fills with soil, ensuring it stays in place regardless of soil movement or rising groundwater pressure.

  • Built to flow

    Our PRO chambers have excellent flow characteristics, featuring high flow-profile walls and smooth internal surfaces for optimal hydraulic behaviour. This guarantees excellent flow characteristics in both normal conditions and, crucially, during the kind of sudden, torrential downpours that are expected to become increasingly common due to climate change.

  • Built to last

    PRO inspection chambers and manholes are the long-lasting solution, providing at least 50 years of reliable service. They fulfill all the requirements set out in the applicable European standards.

Standard and custom chambers and manholes

The PRO manholes offer a huge range of connections to the base and riser rings. In practice, with PRO, engineers can design their ideal manhole without being constrained by standard inlet-angle configurations. We also offer flexible sockets which, if needed, allow for a ± 7.5° correction of the inlet angle. Further informations and specifications can be found in the brochure.

Pipelife PRO manholes are an ideal alternative to concrete and are widely used for:

  • Sewerage revision and inspection
  • Connecting sewerage on different levels
  • Changing the direction of the sewerage path (horizontally and vertically)
  • Changing the slope and vertical section of a sewer pipe
  • Draw tanks for PROFOS sewerage pumping stations
  • Tanks for stormwater
  • Energy reducing
  • Water meter manholes
  • Revision and inspection of telecommunication and power networks
  • Industry-specific needs

More ways to have it your way

The PRO inspection chambers and manholes can be tailored to specific needs. As well as inlet angles and risers, other options include sand and leaf traps, pumping stations and oil separators. The chambers can also be used to reduce the speed at which water flows down steep inclines in mountain and hillside pipeline networks.

A fast and flexible infrastructure solution

A German housebuilding company needed inspection chambers and manholes that could connect with any dimension of standard pipe. The answer: custom-made Pipelife PRO. Pipelife Germany worked out a phased, just-in-time delivery schedule for 50 PRO MH1000 for the main connections, and 94 PRO IC630 for the house connections. And with plug and play connectivity to the standard pipes, all the customer had to do was couple the components at the moment they chose.

Tech insight

Pipelife PRO chambers come with a choice of standard-angle pipe inlets or custom design to meet the need of specific installation sites. The ribbed outer wall that gives the PRO system its lightweight strength also doubles as a locking system: soil fills the gaps and holds the chamber in place should groundwater levels rise.

PRO inspection chambers and manholes are flexible, strong, don't collapse under pressure the way concrete does, don't corrode, and they have a smooth surface for low stickiness. Installation can be performed with smaller and less costly cranes, and smaller crews – crucial benefits given that people and equipment account for the vast majority of the cost of a project.
