EnviroStorm HDPE Perforated Pipe: The Solution for Effective Stormwater Management

Convic Australia offers EnviroStorm HDPE Perforated Pipe 450mm, a cutting-edge solution for managing stormwater effectively. With its advanced design and performance, this pipe provides long-term cost-effectiveness and improved stormwater management. Explore the benefits and applications of EnviroStorm HDPE Perforated Pipe below.

Benefits of EnviroStorm HDPE Perforated Pipe
  • Superior Durability and Performance: The co-extruded twin-wall manufacturing process ensures a high stiffness to weight ratio, making it ideal for non-pressure applications. It resists corrosion and abrasion, providing long-term reliability.
  • Easy Installation and Transportation: Lightweight construction allows for effortless handling and transportation. Quick and secure joint connections ensure a watertight seal, reducing the risk of leaks and infrastructure damage.
  • Resistance to Harsh Environments: EnviroStorm HDPE Perforated Pipe is ideal for use in harsh environments due to its exceptional resistance to corrosion and abrasion.
Infiltration Applications

EnviroStorm HDPE Perforated Pipe 450mm supports stormwater infiltration, mitigating the effects of urbanization and promoting groundwater recharge. It helps address the following issues:

  • Urbanization Effects: Urban development reduces groundwater recharge due to decreased infiltration. EnviroStorm HDPE Perforated Pipe allows for controlled infiltration, replenishing aquifers and managing surface runoff.
  • Groundwater Management: Supports groundwater recharge and prevents issues associated with reduced infiltration, ensuring long-term water availability.

Filter Sock and Compliance: In situations with fine sand and coarse silt soils, EnviroStorm HDPE Perforated Pipe utilizes a filter sock to prevent sediment entry. The filter sock stabilizes soil around pipe corrugations and restricts sediment from entering the drain line. EnviroStorm HDPE Perforated Pipe is manufactured in compliance with AS2439, meeting industry standards for quality and performance.

Enviropipes perforated pipe systems are designed for both subsoil drainage and infiltration of stormwater runoff to help prevent ground water issues.


Sub-soil drainage sytems use a flexible corrugated drainage pipe to maintain a designated water table level based on design requirements , It is ideal for landscape and lawn drainage, and for drainage in areas that are prone to flooding. It can also be utilised in the following applications;

  • Roads and highways
  • Sand and heap leaching for mines
  • Sporting ovals
  • Golf courses
  • Parks and gardens
  • Salinity
  • High rainfall

In situations where there is fine sand and coarse silt soils, a filter sock is used to prevent fine grains from entering the slotted pipe. It also restricts the sediment from entering the drain line by stabilising the soil around the pipe corrugations.

Filter wrap can be supplied separately or fitted onto the coil.


Change in groundwater recharge is one of the many effects of urbanisation. As urban development increases, ground water recharge will decrease due to of reduced infiltration. More surface runoff, less water infiltration into the soil, and less water recharge to aquifers are often a consequence. Enviropipes has developed a flexible corrugated pipe that can recharge and prevent ground water issues.


High Crush Resistance

Enviropipes Perforated pipe is manufactured from high-density polyethylene material with a corrugated profile wall to give high crush resistance, flexibility and lightness.

Enviropipes Perforated pipe is designed for the economic removal of excess ground water in pastures, croplands, orchards, playing fields, roads and construction work. It can also be used in effluent soakage fields, retaining wall drainage and storm water diversion.

Enviropipes Perforated Pipe with Filter Wrap

The thermal bonded filter sock provides the combined functions of filtration and separation which prevent excess particles in the water entering the pipeline.

Features and benefits are

  • Exceptional dimensional stability
  • High tear strength, high tensile strength
  • High resistance to most chemicals
  • Resistant to mildew, moisture and rotting
  • Low pore site to prevent root fibre penetration
  • High permeability to air and water
  • Lightweight and high bulk, specific gravity 0.91
  • Non fray
Pipe Weight

The extremely low weight of Enviropipes Perfrorated Pipe allows simpler and faster installation. Most cases no heavy machinery is necessary for the installation and handling of the pipes. Most of the handling can be done by an excavator on site or even by hand.

Chemical and Corrosion Resistance 

Enviropipes Perforated pipe is manufactured from High Density Polyethylene (HDPE) and has excellent resistance both internally and externally to protect against aggressive soils and chemicals.

Effective Roughness

Due to its low roughness as shown in the graph below there is almost no accumulation on the pipe bottom, Enviropipes Stormwater Pipes and EnviroSewer® pipes have the ability to self purify. Low roughness has an important economic advantage as maintenance expenditure is kept to a minimum. Due to the low roughness the hydraulic properties are improved and smaller diameters are required compared to conventional pipe materials with the same flow rate. Enviropipes Stormwater Pipes and EnviroSewer® pipes convey flows up to 17% greater than concrete pipes, and up to 60% greater than corrugated steel pipes.



Abrasion Resistance

Polyethylene pipes are among the most abrasion resistant pipes in the world. This has been tested in the Darmstadt procedure and the results are shown in the diagram to the left and supports the quality of polyethylene pipes.





Commonly most natural materials and other plastics are degraded by weathering effects, particularly by the combined impact of short-wave ultraviolet radiation in sunlight and atmospheric oxygen. Black polyethylene pipes are permanently resistant to atmospheric corrosion and UV radiation, as the polyethylene used contains carbon black which acts as both a pigment and an ultra violet stabiliser. Thus the pipes can be used and stored outside without the pipe material being damaged.

Resistance to Micro Organisms

Polyethylene is not nutrient media for bacteria, fungi and spores, so that the material is resistant to all forms of microbial attack as well as both sulphurous acid and sulphates


The following step by step procedure is recommended when joining corrugated pipes.



Important information for rubber orientation and cutting of Enviropipes Corrugated pipe from 225-750mm (Please make contact for cutting of all other sizes)

• During installation if the pipes need to be cut to special lengths make sure cuts are made to the centre of the valley only, also make sure to seal the airways when required before installing the last length of pipe (this applies to sizes between 225-750mm only).
• Install rubber in the correct orientation (as per below picture) in the last valley of the pipe and make sure surfaces are clean and lubricated with approved Enviropipes lubricant.
• Rubber notches should be installed in line with the airway of the pipe to avoid any leaks after compressing the rubber
into the socket.
