Plastic Water Pipes

The plastic water pipes manufactured by Peak Pipe Systems offer excellent quality pipe delivered to your project with rapid turnaround times. We work with contractors and building companies across the country to supply our potable and non-potable water service pipes, which supply schools, homes, offices and other developments across the country.

Potable Water Pipe

Our polyethylene pipes for drinking water applications are available in a wide range of sizes to suit all manner of projects. From 20mm through to 630mm OD, we can supply pipes to suit a maximum operating pressure of 16bar and are compliant to EN 12201 and WRAS approvals.

Polyethylene boast several material property benefits which mean it is a highly flexible, robust and sustainable materials to install on our clean water networks. Our water pipes can withstand high pressure applications and are therefore suitable for a variety of industries. Whatever your project’s requirements are, we can help.

Service Pipe

Our PE80 blue potable water service pipe is available in 20mm – 63mm and is identified by a light blue colour. Typically supplied in coils up to 200mtrs, this is a lightweight solution for supplying water service lines up to and into the home.

Mains Pipe

Our mains pipe is available in sizes from 90mm 630mm and made with black core high density PE100 with co-extruded dark blue PE100 skin. Used in buried potable systems up to 16 bar maximum operating pressure.

Straight sticks

We offer straight polyethylene sticks in PE100 (HDPE) in various standard lengths (6mtr, 12mtr and 13.5mtr) which can be joined with electrofusion, butt fusion or mechanical methods.


Preferred method for installers due to a reduction in joints throughout the system. All coils are capped and carefully banded to allow safe transportation, storage and handling on site. Sizes 20mm to 180mm are available and offer many logistical benefits on site and can be installed in a smaller physical footprint area.


Peak offer a full range of butt-welded fabricated fittings from 90mm to 630mm (various SDR). Enabling designers and network operators to service and maintain intricate and complicated networks. Fabricated fittings offer full pressure rated transitions, reduction and diversions within the pipe network which are critical to negotiate around existing infrastructure.

All fabrications come complete with pupped outlets which mean they are suitable for butt fusion, electrofusion or mechanical jointing methods.

  • Mitred bends (various angles)
  • Equal/Reduced Tees
  • Stub flange assemblies
  • Concentric reducers
  • Elbows

Non-Potable Water

PE100 High Density Polyethylene (HDPE) pipe – For potable water above ground, pumped & pressurised gravity sewer systems.

Manufactured from virgin PE100 (HDPE) material, our solid wall polyethylene black pipes are ideal for potable and non-potable water applications. Typically used for pumped and gravity sewer systems, bulk water transfer and raw water extraction. PE100 pipes offer flexibility with high operating pressure capabilities.

We offer non-potable service and mains pipe along with pressure rated fabrications to suit various applications

Benefits of polyethylene pipe

Specifically design to least a targeted 100 years in operation, polyethylene pipelines are favoured by water companies for the delivery of the clear drinking water to millions of homes across the country and for the distribution and removal of wastewater into water treatment facilities.

Polyethylene boast material properties that outperform metallic alternatives and minimise costly maintenance and rehabilitation processes.

  • High flexibility and lightweight
  • Low friction and high flow rate
  • Resistance to corrosion
  • Suitable for various installation methods
  • Cost saving in transportation and installation

Polyethylene has the ability to expand and contract with continuous fluctuating operating system pressures, this continual flexibility whilst maintaining structural strength means the network remains leak free and suitable for continual use in a variety of ground conditions.

Developed due to its ability to be connected via 2 homogenous welding methods, HDPE pipelines can be installed quickly and consistently in cold and warm weather.
