NEVOD - the first in the world Cherenkov water detector (CWD) at the Earth’s surface equipped with a spatial lattice of quasi-spherical measuring modules for the investigations of all basic components of cosmic rays including neutrinos is considered. A large dynamic diapason and close location of quasispherical modules allows use this detector as a Cherenkov water calorimeter for cascade shower investigations and measurements of the energy deposit of muon bundles. Its further development is connected with the widening of the CWD both existing modules and new quasispherical modules consisting of 14 PMTs. Additionally, it is planned to place new optical modules of IceCube, KM3NET and GVD (Baikal) in CWD NEVOD for their common calibration. To sharply increase the accuracy of measurements of energy of various events (cascade showers, muon bundles, EAS cores. etc.) it is proposed to cover inner walls of the water reservoir with optical modules which are now used in the ANTARES experiment.
