Summary of Article: Washing Cars & Waterway Pollution in New Zealand
This article from RNZ (Radio New Zealand) details the regulations and concerns surrounding washing cars and other cleaning activities that can contribute to pollution in New Zealand’s waterways. Here’s a breakdown of the key points:
The Issue:
* Discharging contaminants (detergents, sediment, hydrocarbons, heavy metals) into stormwater drains can harm aquatic ecosystems. Even “biodegradable” products can be problematic.
* Stormwater drains only drain rainwater – anything else is pollution.
Regulations & Enforcement:
* The 1991 Resource Management Act applies nationwide, but specific rules vary by council.
* Councils generally take an “education first” approach,issuing fines only for significant environmental risks or after complaints.
* Fines have recently increased (from $750) to be a more effective deterrent.
* It’s illegal to discharge contaminants into water without consent.
What You Can & Can’t Do:
* Washing Cars: Washing on unsealed ground or grass is better as it provides some filtration, but still isn’t ideal.Washing on hard surfaces that drain directly into stormwater is discouraged.
* House/Roof Washing: Prevent runoff by diverting water to unsealed ground or blocking drains.
* Driveway Cleaning: Using products like Spray & Walk Away, Wet & Forget, and 30 Seconds is technically a violation.
* boat Cleaning: Must be done at dedicated facilities, not on the foreshore.
* Septic Tanks: Must meet local discharge requirements.
Council Initiatives:
* Tauranga City Council: Water education programs for schools.
* Otago Regional Council: “only Drain Rain” and “Adopt a Drain” programs.
* Hamilton City Council: promotes washing cars on grass for filtration.
* Many councils are raising awareness through public campaigns.
Key Takeaway:
Be mindful of where water runoff from cleaning activities goes. The best practice is to prevent contaminants from entering the stormwater system. Check your local council’s regulations for specific rules in your area. “Only drain rain” is the guiding principle.
