We will briefly review the current experimental status and discuss the sensitivity of the future proton decay detectors, and we specifically present a possibility of a scalable multi-megaton water Cherenkov detector immersed in the shallow water.10 pages, 5 figures, Talk presented at the international workshop on Neutrino Oscillations and their Origins, December, 2000 in Tokyo, Japan; also presented at the Baksan School, April, 2001 in Baksan Valley, RussiaHigh Energy Physics - Experimenttext
