Due to the scarcity of water (reducing water supplies and increasing water restrictions), the use of recycled water and rainwater have become more prevalent in Australian society, with local councils encouraging these practices.

Amongst some of these initiatives is the use of colour-coded pipe for connecting to the outdoor hose supply, the toilets and the rainwater tank, so as to avoid cross-connection with potable (drinkable) water supply.
 

Polyethylene  (PE) Recycled Water & Rainwater Systems

Pipe

Buteline Polyethylene Recycled Water pipe is a solid dark lilac colour and Buteline Polyethylene Rainwater pipe is solid emerald green, to make it visually clear to installers that the usage of these pipes are different to that of potable water.
Available in both lengths and coils, the below logos are also featured on our packaging:

Lilac (recycled water) & green (rainwater) pipe


These coloured pipes are manufactured from Polyethylene in accordance to AS/NZS 4130 and are made on a single extrusion process. 

To protect against any possible installer error, our Recycled Water and Rainwater pipes and fittings are all 20mm size so it is physically impossible to accidentally connect to grey Polybutene-1 pipe (used for potable water supply).
