The Aqua-Guardian™ can be used in most standard catch basins or storm drains, regardless of age or location. AquaShield™ can custom-fabricate the stainless steel support collar to fit nearly any size or shape of existing catch basin. The dimensions or diameter of the surface drain opening need to be accurately described on the Aqua-Guardian™ Aqua-Site worksheet.

Installation is as simple as removing the surface grate cover and lowering the Aqua-Guardian™ into the catch basin. Due to the lightweight nature of HDPE, the Aqua-Guardian™ units can be installed without the need for special lifting equipment. However, removal and handling of the storm grate cover may require lifting equipment due to its weight and size.

The stainless steel support collar on the Aqua-Guardian™ is custom sized to fit inside the surface grate's frame. The flange on the stainless steel support collar will rest on the same rim that receives the surface grate cover. Once the insert is properly seated on the metal rim, replace the grate cover.

A routine inspection and maintenance program is established for each unit based on the volume or load of the contaminants of concern, the frequency of releases of contaminants at the facility or location, and the nature of the area being drained. Typically, the Aqua-Guardian™ should be inspected quarterly or after significant storm events.

The Aqua-Guardian™ Catch Basin Insert can be visually inspected from the surface without the need to remove the catch basin grate. Simply use a tape measure to gauge the amount of sediment in the collection area. When sediment level reaches the bottom of the perimeter filter screen outlets the unit should be serviced.

The first step to maintain the Aqua-Guardian™ Insert requires the removal of the surface grate cover. A wet/dry shop-vac is often used to remove debris and sediment collected inside the chamber. The locking centerpiece assembly is removed by rotating the assembly with the T-handle on top of filter screen standpipe. Once the centerpiece assembly is removed, the filter bag will be visible so that it can simply be pulled from the Aqua-Guardian™. Cleanout any residual sediment in the filter area and place a new filter bag in the unit. Press down on all sides of the newly installed filter to ensure good contact with the outside walls.

The centerpiece assembly is replaced and rotated (or locked) under the fitted guides. The final maintenance step is to replace the surface grate cover to its normal position.
