Installation
1. Refer to approved plans for location and installation details. If there are questions or problems with the location, dimensions, or method of installation, contact the engineer or responsible on-site officer for assistance.
2. Ensure that the installation of the sediment trap will not cause undesirable safety or flooding issues.
3. Install sediment trap in accordance with standard drawing supplied with the approved plan, or as directed by the site supervisor.
4. Ensure the sediment trap fully encloses the kerb inlet. Use appropriate spacers to ensure the sediment trap does not block the side-entry inlet.
5. If necessary, install additional 'on-grade kerb inlet sediment traps' up-slope of the sag inlet to adequately retain the expected quantity of sediment runoff.
6. Take all necessary measure to minimise the safety risk caused by the structure.

Maintenance
1. Inspect all sediment traps daily and immediately after runoff-producing rainfall. Make repairs as needed.
2. Remove collected sediment and dispose of in a suitable manner that will not cause an erosion or pollution hazard.
3. Ensure sediment does not enter the stormwater drain during de-silting operations and maintenance of the trap.
4. Sediment on the road shall be removed immediately if it represents a safety hazard.

Removal
1. When the up-slope drainage area has been stabilised, remove all materials included deposited sediment and dispose of in a suitable manner that will not cause an erosion or pollution hazard.
