Council concerned about contamination of stormwater systems
 

Recent pollution of urban waterways has prompted the Taranaki Regional Council to remind the public and businesses not to contaminate stormwater systems.

The only thing that should enter a stormwater drain is clean rainwater, says Council Compliance Manager Bruce Pope.

“A number of recent incidents in New Plymouth and Bell Block, for example, highlight the need for the public to be aware of the impact of discharges of contaminants into or near stormwater drains.”

The incidents included run-off from the cleaning of paint brushes and other painting equipment entering the stormwater system, along with intentional or unintentional discharges of fuels and oils.

“Care must be taken not to discharge any industrial waste into the stormwater system,” says Mr Pope.

“Any pollution will be investigated and appropriate action taken. The Taranaki Regional Council and the New Plymouth District Council are working together to spread the word on keeping contaminants out of all stormwater systems.”

The District Council uses fish symbols to mark some drains to indicate they run straight to waterways – but Mr Pope says contaminants should not go into any drain, regardless of whether or not it is so marked.

“Stormwater drains are designed to collect rainwater from open areas such as roads, roofs and car parks, and most flow directly to the nearest natural waterway,” he says

“So any contaminant that’s washed, spilled or illegally dumped down a stormwater drain may end up polluting a waterway. And any pollution entering a river, stream, lake or ocean will harm the aquatic insects, fish or plant life living there.

“Stormwater systems can be contaminated by outdoor cleaning chemicals, fuel spills, soapy water from vehicle washing or cleaning painting equipment near a stormwater drain. Wherever possible, people should make sure that contaminated waste water goes to a collection system for treatment or to a municipal wastewater treatment system.

“No one should be tipping anything down a drain or grate,” Mr Pope says.

The public can notify the Taranaki Regional Council on the Environmental Hotline, 0800 736 222, if they notice any contamination of a drain or waterway.

“We do rely on the public to report these incidents and will do everything we can to find the source of the pollution,” says Mr Pope.

“We will make sure that those responsible are made aware of the consequences of their action and if necessary the Council will take further action to get assistance with the clean-up or if necessary take enforcement action.”
