Stormwater Pipes
AS/NZS 5065:2005

Case Studies
PROJECT SUMMARYEsperance Freight needed to expand its storage yard at Glenferrie Rd, Welshpool, Western Australia which required a drainage system that could withstand heavy haulage vehicles and at the same time be cost effective. The solution was to install Enviropipes. Enviropipes comply with AS/NZS 5065 PRODUCT DETAILSENVIROPIPES (POLYPROPYLENE) DRAINAGE PIPES

Applications
Subdivision and Water Management
Enviropipes manufactures storm water pipe systems in diameters from 100mm up to 4000mm which provide outstanding storm water management capacity as well as out performing other storm water systems. High Density Polyethylene (HDPE) pipes collect storm water runoff through a surface inlet and drain it to an appropriate outlet. Storm water systems can be small and simple, such as that used for a modest housing development, to complex systems used in metropolitan areas serving a combination of residential, commercial, and industrial developments.
Parking Lot for Storm Water Drainage
Incorporating engineered pipe, catch basins, and curb inlets, a sound storm water management system will keep parking lots well drained and prolong the service life of the paved structure.

Sub Drains
A sub-drain system is an underground network of piping used to remove water from areas that collect or retain surface water or groundwater. The network can be small, such as those used to drain a limited area, or large draining a sizable number of acres.
Surface water can be collected into the sub-drain system by installing a surface inlet or catch basin. Groundwater is collected by allowing water into the pipe through perforations. Both surface water and groundwater can be discharged to an appropriate outlet.
Culverts
Enviropipes High Density Polyethylene (HDPE) Culverts are manufactured from 100mm up to 4000mm ID and can be used on any main road network such as access roads to mine sites or river crossings. Our non-corrosive culverts are also suitable for rail networks as they offer a high stiffness to weight ratio making them easy to install.

LNG, Waste Water Treatment Plants and Mine Sites
Enviropipes Stormwater Pipe can be used for site drainage and underground water storage. The use of Enviropipes Stormwater Pipe is advantageous as the rubber ring jointed pipes require no further welding or couplings. Our pipe offers high resistance to abrasion and corrosion which is important when considering installing into aggressive soils.

Jointing
Enviropipes Stormwater Pipes are rubber ring jointed and each pipe is supplied with an EPDM rubber seal.
The following procedure is recommended when jointing Enviropipes Stormwater Pipes.
Important information for rubber orientation and cutting of Enviropipes Corrugated pipe from 225-900mm (Please contact your nearest Enviropipes branch 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 before installing (this applies to sizes between 225-900mm only contact your nearest Enviropipes branch for cutting of all other sizes)
- 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
