The extremely low weight of EnviroSewer® pipes 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.
Cost Effective Solutions
Storm water applications demand high performance and minimised cost. EnviroSewer® pipe is a competitively priced solution compared to alternate systems. Installation costs of High Density Polyethylene (HDPE) systems are generally lower than other pipe materials, due to its light weight and jointing systems. Fast installation minimises traffic disruption and other nuisance factors associated with underground installations.
HDPE (PE100) pipes have proven reliability across a range of applications of around 50 years. The Water Services Association of Australia (WSAA) Polyethylene Pipeline Code predicts a life in excess of 100 years before major rehabilitation is required.
EnviroSewer® Pipes are all rubber ring jointed which results in faster installation.
The installation time is shorter than other materials as the standard pipe lengths are between 5.5 to 6 meters long. Fewer lifts mean unloading and loading the pipes into position saves even more time.
Chemical Corrosion Resistance
EnviroSewer® Pipes manufactured from HDPE (PE100) have excellent resistance internally and externally to protect against aggressive soils, chemicals and corrosion.
Due to its low roughness as shown in the graph above there is almost no accumulation on the pipe bottom 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. EnviroSewer® pipes convey flows up to 17% greater than concrete pipes, and up to 60%better than corrugated steel pipes.
Polyethylene pipes are among the most abrasion resistant pipes. This has been tested in the Darmstadt procedure and the results are shown in the diagram above and support 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. 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.
