Abstract: This report presents the concept and results of simulation of a system of underground water Cherenkov detectors, which is planned to be added to the TAIGA astrophysical complex for joint operation with the TAIGA-HiSCORE Cherenkov array. It is shown that this system, by registering the muon component of extensive air showers, will make it possible to more accurately measure the mass composition of cosmic rays and effectively separate cosmic gamma rays from the background of charged cosmic rays with energies above 1 PeV.

Keywords: Taiga gamma observatory, cosmic rays, extensive air showers, corsika, water Cherekov detectors.
