Recently, the writers proposed a new method for optimal design of diameters and slopes of pipes of storm sewer networks. Uncertainties from various sources are considered and a tradeoff is made between potential rainstorm flood damages and the coast of installation of the sewers. One key step in the proposed method is the establishment of the risk-safety factor relationship. Through a numerical example, this paper presents the details of procedure to establish the risk-safety factor relationship. The usefulness of the relationship so established is neither restricted to the optimal design method proposed.
