SewerMAX® is a cost-effective sewer pipe system suitable for gravity trunk sewer mains. Manufactured from polypropylene, SewerMAX® pipes are highly resistant to chemical attack which can be common in sewerage and industrial wastewater pipelines. The material is also resistant in aggressive ground conditions, such as acid sulphate soils or saline ground waters.
Iplex SewerMAX® pipes and fittings are suitable for installation in the following applications:
- Gravity sewers
- Industrial trunk sewers
- Rehabilitation of failed pipes with slip lining techniques
BlackMAX® SewerMAX® and SewerMAX+® Technical Guide
Throughout Australia SewerMAX® has been chosen for its unique characteristics and properties including:
|Durability||The tough, ductile nature of polypropylene enables pipes to resist impacts sustained in the course of transportation and site handling, without damage|
|Abrasion and corrosion resistant||Polypropylene is notably resistant to abrasion and has excellent resistance to corrosive drainage. The material is resistant to aggressive ground conditions, such as acid sulphate soils or saline ground waters|
|Effective rubber ring joint||Designed for ease of assembly and jointing. Pipes can be cut to length on site and rejoined|
|Low embodied energy||Environmental benefits|
|Inground performance||High tolerance to deformation and can accommodate soil movement without structural damage|
|Smooth bore for hydraulic performance||Combined with their high resistance to scale and sediment build up provides excellent hydraulic performance. This can result in reduced grades to accomplish a given flow|
|Lightweight for ease of installation||Can be easily manoeuvred in confined areas by hand or with light lifting equipment. Site handling and efficiency is therefore improved, which can result in significant savings on installation|
|High pipe stiffness||Suitable for deep installations|

Polypropylene is inherently resistant to a wide range of chemicals such as acids, alkalis, salts, wetting agents and alcohols. It is however attacked by oxidising acids such as fuming nitric acid or hot concentrated sulphuric acid, neither of which should be encountered in a drain. Polypropylene is swollen and softened by halogenated solvents (for example, trichlorethylene) and hydro-carbon solvents such as xylene and benzene. However, the effect is not immediate and the occasional contact with solvents such as petrol or diesel is acceptable for PP pipes used for drainage and sewerage applications.
SBR seals are also resistant to a wide range of chemicals such as salt solutions, alkalis, glycols and some alcohols. SBR is swollen by a number of organic solvents, however, the seals are encapsulated in the pipe profile and to a large extent, isolated from the contents of the pipe. As only a small part of the seal surface is in contact with liquid in the pipeline, any occasional spillages or illegal dumping of chemicals should have a minimal effect.
Standards and Approvals
SewerMAX® pipes and fittings are manufactured to the Australian Product Standard under third-party accredited Quality Management System (QMS) conforming to ISO 9001.
SewerMAX® pipe has ISO Type 5 third-party StandardsMark™ Certification, License number SMXXX accordance with AS/NZS 5065 “Polyethylene (PE) and polypropylene (PP) pipes and fittings for drainage and sewerage applications”.
SewerMAX® pipes and fittings have been appraised by Water Services Association of Australia (WSAA) for performance compliance with AS/NZS 5065 (WSAA Appraisal 03/05).
Iplex Pipelines has published verified Environmental Product Declaration (EPD) on our range of Polypropylene pipes. EPD’s are third party certified documents based on ISO 14025 and EN 15804 Standards that communicate transparent and comparable information about the life-cycle environmental impact of a product or service. Specifically, product declarations include information on the environmental impact of raw material acquisition, energy use and efficiency, composition of materials and chemical substances, emissions to air, soil and water and waste generation.
SewerMAX® Pipe Range and Dimensions
SewerMAX® pipes are available in diameters ranging from DN225 through to DN600 in SN10.
SewerMAX® Fittings Range
A range of standard fittings, including bends, tees, junctions, closed ends, couplings, plugs, reducers, saddles and adaptors are manufactured for use with BlackMAX® and SewerMAX® pipes. Fittings can be fabricated from BlackMAX® or SewerMAX® pipe sections, PVC pipe sections, GRP / PVC and GRP / VC composite materials.
GRP, GRP/PVC and GRP/VC composite fittings are manufactured specifically for use with SewerMAX® pipes with socketed ends for connection to SewerMAX® pipe spigots. GRP fittings are also available with PVC or VC socket or spigot ends for lateral connections to incoming PVC or VC sewer pipes. GRP SewerMAX® fittings comply with Australian Standard Revision AS3571 “Glass reinforced thermosetting plastics (GRP) pipes – Polyester based – Water supply, sewerage and drainage applications”.
BlackMAX® and SewerMAX® pipes are manufactured with a spigot and socket rubber ring jointing system. A profiled ring is located in the second trough from the spigot end and is compressed as the spigot enters the socket. This jointing system can be used after cutting the pipe anywhere along its length. Joined pipes may be deflected by up to 3 degrees off-line after assembly.
A range of stainless steel, jointing and repair clamps are available in sizes DN225, DN300, DN375, DN450, DN525 & DN600 for repairs and maintenance of SewerMAX® pipes. SewerMAX® Stainless Steel Junction with reducing DN100 and DN150 DWV branch off-takes at 45° are also available, simplifying lateral side connection to property branch sewer lines without the need of cutting-in a new junction. The stainless steel junction and clamps have been designed specifically for SewerMAX® and comply with the requirement of Australian Standards "AS4181 Stainless Steel Clamps for Water Work Purposes".
SewerMAX® Rubber Ring - Poor joint performance can lead to major problems with your asset. An inadequate joint can allow tree root intrusion, which can lead to pipe blockages and ground water infiltration. Infiltration through the pipe joint can also cause silting of the pipeline and long-term maintenance issues. For this reason, the duality of the joint is critical to the performance of any pipe system.
The SewerMAX® pipe joint has been designed to meet the performance requirement of "AS/NZS 5065 Polyethylene and Polypropylene Pipe and Fitting for Drainage and Sewerage Application". The standard specifies a pressure test of 85 KPa and a vacuum test of - 85 KPa as well as a minimum contact pressure of 0.4MPa between the rubber seal and the pipe wall over a distance of at least 4mm. These conditions have shown to provide high resistance to tree root intrusion for plastic pipes.
