Résumé	The problem of frozen water service lines in severe cold winter months can be costly to municipalities across Canada. During the 1993/1994 winter 2,745 water service lines were frozen in the Region of Ottawa-Carleton and the corresponding cost of thawing was approximately $2.2 million or $800 per service line. The Region has since implemented a procedure to minimize the number of frozen services and corresponding costs in the subsequent winters by sending alert notices to the residents advising them to let water run from a faucet. The procedure is based on frost depth prediction using Brown's formula and daily mean air temperature forecast. Moderate correlation between the number of frozen services and freezing index was found using the region's statistics of frozen services.
