Many of the curious thermodynamic properties of water can be traced back to the unique patterns of Hydrogen bonding, which lead to the formation of a percolating H-bond network even in the liquid phase. We develop and study a semi-empirical lattice model for this H-bond network, and study it on an infinite-dimensional lattice. We show that the model gives accurate predictions for the network correlations even at normal temperatures and pressures. We also study the phase diagram, leading to a new hypothesis for the origin of the anomalous properties of water.
