CPV 904 – Sewage Services

What does CPV 904 cover?

CPV group 904 covers services for the conveyance, treatment, and disposal of sewage. These include the cleaning and inspection of sewerage networks, the operation and maintenance of sewage treatment works, sludge treatment and disposal, the management of combined sewer overflow events, and emergency services for sewer incidents. The creation of sewer registers, hydraulic modelling, and general drainage planning may also fall under this code.

Municipalities and municipal wastewater associations are the central contracting authorities. They procure operational services for sewage treatment works where in-house operation is not economical, and regularly award cleaning services for their sewerage networks to specialist companies. Sewer cleaning and inspection services are frequently tendered in combination: CCTV camera surveys and high-pressure jetting go hand in hand.

The EU Water Framework Directive and the Urban Wastewater Treatment Directive are shaping requirements for municipal sewage works in significant ways. Municipalities must invest substantially in the coming years in expanding sewage works capacity and in fourth-stage treatment (micropollutant removal). These investment projects give rise to extensive procurement for planning, construction, and operational services. Further information on the CPV system is available from the European Commission (SIMAP) and Regulation (EC) No 213/2008.
