This European Standard applies to the investigation and assessment related to the cleaning of drainage and sewer systems outside buildings and specifies a coding system for recording the extent and type of cleaning required.
It is applicable to drain and sewer systems, which operate essentially under gravity, from the point where the wastewater leaves a building or roof drainage system, or enters a road gully, to the point where it is discharged into a treatment works or receiving water. Drains and sewers below buildings are included provided that they do not form part of the drainage system of the building.
Further guidance on how to carry out cleaning in different countries should be taken from EN 14654-3 and relevant national documents. This part of the European Standard specifies a coding system for the description cleaning methods and observed conditions made inside sewers and drains, manholes and inspection chambers identified through visual inspection. Where appropriate, it can also be used for pressure and vacuum systems in accordance with the requirements of the employing authority. Visual inspection of drain and sewer systems can be carried out as part of the investigation in order to undertake the assessment.
This part of the European Standard does not generally specify requirements for carrying out inspections. Inspection will be typically carried out with the aid of cameras propelled by various means, or by personnel entering the drain system i.e. manual entry inspection.
General documentation required during cleaning and disposal activities (e.g. vehicle data or waste disposal certificates) is also recorded with the coding system.
