UP-FLO FILTER MAINTENANCE
Up-Flo filters protect our waterways by removing pollutants from stormwater runoff. Regular maintenance of these filters is essential to the performance and long-term durability of the filter.
The Up-Flo filter is an advanced stormwater filtration device. They typically take the form of a 1200mm diameter manhole structure, but larger vault systems can be used for more substantial sites.
Each filter module has an angled screen and a support bracket, these are attached to a concrete wall. The filter module has a media pack inside it containing:
- Mathala – flow distribution layer;
- two bags filled with media – the media is specified in your resource consent;
- one more flow distribution layer on top.
The Up-Flo filter is designed to allow larger pollutants to settle in the main sump (a hollow where the liquids collect) before the water flows upward through the screens, then through the filter media and into the outlet.
Typically, Up-Flo filters require maintenance either six monthly or yearly. A recommended service frequency will be advised as part of your service report.
The frequency of maintenance services will be reviewed by Dutton Stormwater at the completion of each service and this recommendation will be included in the service report.
