Identifying industrial drainage assets and maintenance needs
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.
Asset details: manufacturer, model, capacity and drawings, where available.
Drainage duty: the area or process served and the oil, residues, sediment or other contamination it may receive.
Maintenance history: previous emptying or inspection, reported defects and recurring problems.
Access and discharge: cover locations, connected drains, outlet arrangement and known discharge destination.
Technical sources for this library
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.
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.
Maintenance notes
Manufacturer, system model and installed inspection-channel configuration.
Channel locations, previous inspection findings and any recorded sediment build-up.
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.
Maintenance notes
As-built layout and the type and location of each access point.
Previous inspection findings, material observed and the location of any flow-control component.
Green-roof storage cells are part of the roof’s water-management design. The installed layout, outlets, overflow arrangement and manufacturer information set the maintenance context.
Maintenance notes
System manufacturer, layout, outlets and overflow arrangement.
Previous maintenance findings and any reported drainage or storage problem.
