What does CAEN 37 mean?
CAEN division 37 (rev. 2) is “Sewerage”, with one activity class, in section E — Water supply; sewerage, waste management and remediation activities. Eligibility is checked against the exact class (4 digits) in the programme's list.
How many active companies are there in sewerage and wastewater treatment?
384 active companies have their main CAEN code in division 37; 258 had employees in their latest financial statements and 30 were established in the last two years. Most are in Ilfov (48), Bucharest (46) and Timiș (24).
Does it matter whether the CAEN code is primary or secondary?
It depends on the guide: some programmes require the funded activity to be the main code, while others accept a secondary code authorised at the investment location. Companies now hold codes under CAEN revision 2 or 3; the lists here include the equivalences between the two revisions.
