Oil is a common cause of water pollution and even a small amount has a significant negative effect on plants and animals. It can also make water unfit for drinking or irrigation.
Even a very small quantity of a pollutant, or just one accidental discharge, can drastically alter the quality of a stream. Fish, insects and plants can be killed and habitats destroyed. A waterway can take years to recover.
Filter and reuse oil where possible.
R.O.S.E. (Recovering Oil Saves the Environment) is a scheme set up with the purpose to manage and contract the collection of use (waste) oil to be reused as an alternative fuel source to diesel, light fuel oil (LFO), and gas. R.O.S.E promotes reusing the used oil to assist in minimising the potential for illegal discharges to the environment and to provide a sustainable end use for waste oil products.
Take to the Whanganui Resource Recovery Centre which has a R.O.S.E. container for waste oil (fees apply). Customers must take their used containers away.
Always dispose of waste oil conscientiously.
