Aquädukt

From BoardGameGeek:

Building houses isn't hard - but providing water is much more so. By following this ancient Roman building principle, a prosperous landscape is settled by the players. But the beautiful houses are useless without water. If a player doesn't provide water for his houses before the neighborhood is completely built up, then the inhabitants - good or bad - must move out and the house brings no victory points. He who uses tactical cunning and a little dice luck to build wells and canals at the right time and secure the best building spots will win! Contents: 1 game board, 112 building tiles (8 tiles with 1 house, 8 tiles with 2 houses, 8 tiles with 3 houses, and 4 tiles with 4 houses... in each of the four colors), 8 mountains, 5 (glass) springs, 36 (wooden) canals, 1 20-sided die.
