1. Why do I have to have my stormwater treatment device maintained?

Just like any other filter, these filters clog up with oil, silt, vegetation, litter and other pollutants. Once they are blocked they will not operate as designed. This will mean dirty untreated water will enter our waterways having detrimental effects on the ecosystems and ocean life.

2. Who is responsible for maintaining these devices?

Each property has a consent holder. This may be an individual or a body corporate. It is the consent holder's responsibility to ensure the stormwater system is maintained.

3. When should these devices be maintained?

4. How do I know if I have one of these devices on my property?

This will be stipulated in your Resource Consent. If you are unsure and would like the stormwater system on your site evaluated, feel free to give us a call and we will visit your site at no cost.

5. What does it cost to have one of these devices maintained?

Unfortunately there is not a ‘blanket’ charge for cleaning these devices. The cost varies on the size of the device and the amount of material we have to remove and replace. It is however free to get one of our team out to see you to give you a no-obligation quote.

6. What are the consequences of us not having these devices maintained?

It is a legal requirement to have your stormwater system maintained. ARC compliance officers check sites to see if they are being maintained. If maintenance is not occuring, there is a possibility of a large fine.

There is the environmental impact of having untreated stormwater entering into our rivers and seas.

There is also the danger that the system will overflow and a manhole lid could shift. This can be dangerous for vehicles and pedestrians.

7. How long does it take to maintain our stormwater system

Although the time required for a service varies from site to site, a full service normally takes between two to three hours, and a general service will take between one and two hours.
