The KM3NeT collaboration is constructing new-generation neutrino detectors in the Mediterranean Sea. The main goals are the study of the high-energy neutrino flux (KM3NeT/ARCA, off-shore Capo-Passero, Italy) and the determination of the neutrino mass ordering (KM3NeT/ORCA, off-shore Toulon, France). This contribution describes the system to collect, transfer and process the data, which consists of time and intensity measurements of photons recorded by photo-multiplier tubes resulting from charged products from neutrino interactions, together with data from the acoustic position system. The trigger and data-acquisition system faces the challenge of transporting up to 30 Gbps of data to shore and filtering the neutrino signal from an overwhelming (O(107)) background due to photons from ambient 40K and bioluminescence.
