Cesspits made of glass-fibre reinforced plastic (GFRP)

Cesspits are watertight tanks for domestic waste water containing faecal matter (sewage). Given that cesspits are not connected to the sewer system, professional emptying and disposal must be carried out at regular intervals.

European Technical Assessment (ETA)

To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
