Oil separators, silt traps, catchpits and attenuation systems do different jobs. The maintenance approach depends on the asset installed, what drains to it and where the system discharges.
The references below support the drainage, product and pollution-control information used in these guides. Manufacturer literature is specific to the product or system named and is not a specification for an unidentified installation. Regulatory guidance should be read within the jurisdiction and scope stated by the source.

Stormwater systems
Inspection channels are product-specific access routes within some attenuation systems. Their position and size govern which parts of the storage system can be viewed or reached.
Stormwater systems
Attenuation-system access points should be identified from the as-built layout and manufacturer information. Their position defines where inspection or sediment removal can be attempted.
Drainage equipment
Drainage access covers protect openings while allowing access to the chamber or asset below. Safe opening depends on the cover condition, its lifting arrangement and the loading or traffic around it.
Underground drainage
Inspection chamber bases bring drainage branches through a defined channel layout. The branch arrangement is important when tracing restricted flow or sediment within the chamber.
Underground drainage
Rodding points give purpose-made access to a drain run. Their usefulness depends on their position, the direction of the pipe and the section of drain they can reach.
